Opis:

In this paper a theoretical analysis of load cases will be constructed, which are the most difficult to be determined during numerical simulations. The development of the design principles and methods are significantly influenced by technology development. Inappropriate design procedures and incomplete knowledge of the loads presents a significant risk factor. A strong emphasis should be put on determining the applicable conditions of coating layered optical photostress investigations for simplification of product validation. Future research should be focused on the views of industry representatives. Particular attention should be paid to the further clarification of the used 3D printing material properties and characteristics because these determine the conditions and limits of applicability. This would be a new application field of 3D printing.

Opis:

The spatial FDM Technology printing enables illustrating a great number of technical issues by creating a model of the analyzed object e.g. directly, during didactic classes. A three-dimensional printer may be used in any field of knowledge, from biology, where the printer can be employed for printing the models of organs (printing of the organs themselves is also possible following the modification of the printer - when printing with TAULMAN Nylon filament, we can print e.g. the elements of bones or cartilages which may be implanted into a living organism) to printing spare parts and prototype elements for equipment, in architecture for printing complex scale models etc. The printer itself is a fantastic device, interesting for many fields of study. The 3D printer will enable students to learn how to program the processors based on ATMega, may prepare new software controlling the printer, design 3D graphics on computers, edit “scans” and files downloaded from the Internet, use the CAD software in practice and print the results acquired on the sets of printers. Moreover, each printer may be freely modified according to our own needs - from the change or transfer of the drive to replaceable extruders - the mechanisms forcing materials. The printer may also be changed into a laser plotter or even a milling machine following a slight modification of the extruder’s carriage or changing force belts into ball screws [1-4].

This chapter describes the methodology of obtaining polylactide (PLA) biocomposites with the TiO2 modified by organosilicon compounds: disiloxane and functionalized octaspherosilicate designed for use in additive technologies. The paper presents general information about polylactide, titanium dioxide and the used organosilicon modifiers (silsesqioxanes and polysiloxanes). In the paper the authors compare the effect of two types of TiO2 from different manufacturers on the properties of polymer biocomposites, which can be used in biomedical applications. The properties of the obtained composites with the use of additive FDM technology were characterized mechanically (tensile strength, flexural strength, impact strength), and the particle size of the TiO2 pigment nanofillers used was measured. All the composites were pretreated using a plastic processing technique with two different mass ratios of TiO2 filler content (1.5%; 0.5%). The properties of PLA/TiO2 composites depend on the filler concentration. The applied fillers had a positive effect on the improvement of the mechanical properties of the produced polymer composites. This effect was additionally intensified by the introduction of organosilicon modifiers.

Opis:

The NMC (New Media Consortium) Horizon Report in 2014 listed 3D printing as a technology that is two to three years from widespread adoption. In this report, 3D printing was also classified as a disruptive technology especially for the manufacturing sector. A review of the current literature ranging from journal publications to news reports of how 3D printing technologies are changing the way teachers teach and students learn is the focus of this report. 3D printing technologies include 3D printers, 3D scanners and the recently introduced 3Doodler pen. The widespread rise in popularity of 3D printing technologies is directly correlated with their availability at a lower cost in the consumer market. 3D printing technologies are causing educators to refocus attention from the digital or virtual environment to the real world, where 3D printed objects can be touched and felt. The stl (stereolithography) file is the common file type used for 3D printing and although CAD (computer-aided design) software is the ideal software for making stl files, there are other software choices for producing CAD-free stl files like PhotoToMesh and 123D Catch. How 3D printing technologies are currently being used across the curriculum by teachers as well as students demonstrates the increasing interest in and success with its usage in the learning environment. The growing interest in making and using 3D printed tactile learning objects by the blind or visually impaired points to a future where image-intensive courses and textbooks will have available 3D prints when touch is the primary method for learning. 3D printing and related technologies appear poised to become even more significant as it becomes clearer from the work of early adopters how best these technologies can be employed for teaching and learning.

Opis:

The paper deals with 3D printing of technical objects at 3D printer GERMAN RepRap X400. This printer is designed for large format industrial 3D printing. The paper focuses on technology of 3D printing, preparing of geometrical 3D model for printing with use freeware Repetier Host and commercial software Simplify, comparing these programs, setting the parameters for 3D printing from the perspective of quality of printed objects and 3D printer control from afar with using software Repetier Server or other freeware. It is possible printing with different materials, not only standard ABS and PLA. The printer has DD3 Dual extruder. The extruders can be heated to 290°C. Maximum temperature of heated bed is 120°C. Printing Plate Carbon is used for 3D printing or other preparing pad. This paper also includes verification of correct temperature distribution of heated bed by thermal imaging camera. On the basic experiments by thermal imaging camera, it was found the fact that the temperature difference of actual and set temperatures of a heated bed are increasing with increasing temperature. If the bed temperature is to be at real 60°C, then setting must be approx. 6°C higher, so the set temperature must be 66°C. In contrast, the control of the extruder nozzles confirmed that the actual temperature is nearly such as the set temperature.
Artykuł dotyczy druku 3D obiektów technicznych w drukarce 3D GERMAN RepRap X400. Ta drukarka jest przeznaczona do przemysłowego druku 3D w dużym formacie. Artykuł koncentruje się na technologii druku 3D, przygotowaniu geometrycznego modelu 3D do druku z wykorzystaniem darmowego oprogramowania Repecier Host i komercyjnego oprogramowania Simplify, porównując te programy, ustawiając parametry druku 3D z perspektywy jakości drukowanych obiektów i sterowania drukarką 3D z daleka przy użyciu oprogramowania Repetier Server lub innego bezpłatnego oprogramowania. Możliwe jest drukowanie przy użyciu różnych materiałów, nie tylko standardowych ABS i PLA. Drukarka ma podwójną wytłaczarkę DD3. Wytłaczarki można ogrzać do 290°C. Maksymalna temperatura podgrzewanego złoża wynosi 120°C. Printing Plate Carbon służy do drukowania 3D lub innych podkładek przygotowawczych. Artykuł zawiera również weryfikację prawidłowego rozkładu temperatury ogrzewanego złoża za pomocą kamery termowizyjnej. Na podstawie podstawowych eksperymentów przeprowadzonych za pomocą kamery termowizyjnej stwierdzono, że wraz ze wzrostem temperatury wzrasta różnica temperatury rzeczywistych i ustawionych temperatur podgrzewanego złoża. Jeżeli temperatura złoża ma wynosić rzeczywiście 60°C, ustawienie musi wynosić ok. 6°C wyżej, więc ustawiona temperatura musi wynosić 66°C. Natomiast sterowanie dyszami wytłaczarki potwierdziło, że rzeczywista temperatura jest prawie taka jak temperatura zadana.

Opis:

Rapid prototyping (RP) is being recognised as a significant technology for future product development. One of the most effective RP technologies is 3D printing. A three dimensional object is created by layering and connecting successive cross sections of material. Therefore this new RP methodology is generally faster, more affordable and easier to use than any other additive fabrication technologies. This paper analyses performance of RP methods and compares these based on use-cases. Prototypes of casing type details have been created using different RP technologies. Productivity of product development process and 3D printing has been investigated. A problem in differences between physical prototypes compared to existing computer model (digital prototype) can be diminished by using comparative pre-testing. Case studies of increasing innovation capacity in development of casing type details have been analysed. In addition, suggestions for increasing innovation capacity and performance of rapid manufacturing have been made.

Opis:

Purpose: Thermoplastic polyurethanes (TPU) found application in mining. Due to the excellent processing properties, thermoplastic polyurethanes can be also use to make elements that would facilitate miner's work. These elements, however, differ in dimensions depending on the person who is going to use them, that is why they should be personalized. In case of all the above studies, the elements or stuffs were made by means of the injection method. This method limits the possibility of producing mining’s stuff only to models that have a mould. The 3D printing technology developing rapidly throughout the recent years allows for high-precision, personalized elements’ printing, made of thermoplastic materials. Design/methodology/approach: The samples from thermoplastic polyurethanes were made using 3D printing and then subjected to the aging process at intervals of 2, 7 and 30 days. The samples were then subjected to a static tensile tests, hardness tests and FT-IR spectroscopy. Findings: The obtained results of mechanical tests and IR analyses show that the aging process in mine water does not affect the mechanical properties of the samples regardless of the aging time. IR spectral analysis showed no changes in the structure of the main and side polyurethane chains. Both mechanical and spectral tests prove that polyurethanes processed using 3D printing technology can be widely used in mining. Research limitations/implications: Only one type of TPU was processed in this work. Further work should show that synthetic mine water does not degrade the mechanical properties of other commercially available TPUs. Practical implications: The additive technology allows getting elements of mining clothing, ortheses, insoles or exoskeleton elements adapted to one miner. Originality/value: The conducted tests allowed to determine no deterioration of the mechanical properties of samples aged in synthetic mine water. TPU processing using 3D printing technology can be used in mining.

Opis:

Transition of the real world into the virtual world has been ongoing in online and on-ground classrooms and labs for many years. But the more the world goes virtual, the more difficult it becomes for those who are blind or visually impaired to participate fully in the learning process. The main thrust of this report is to explore how 3D printing and the use of conductive filament can begin to reverse that process by making 3D printed talking tactile learning objects that can generate audio when touched after being placed on the surface of an iPad or other tablet computer. Examples of talking tactile learning objects from STEAM (Science, Technology, Engineering, Arts and Math) disciplines will be presented with a focus on how the design of 3D printed STEAM learning objects can lead to a common learning object template model. The template can be designed to serve as a learning tool not only for a blind or visually impaired student but also can work as well for a sighted student or a teacher, aide or parent demonstrating how universal design principles can drive the learning object production process.

Background: For about 20 years we have been observing the development of three-dimensional (3D) printing. The aim of this study was to systematize the current knowledge on the use of 3D printing technology in neurosurgery and to aetmpt an outline the future paths of its development. Material and methods: The analysis was based on English-language literature from 2017-2021 indexed in the Mendeley and Scopus databases. Results: The application of 3D printing in neurosurgery concerns: 1) teaching students, 2) training of residents neurosurgeons, 3) individualized surgery planning, 4) dedicated cranial and spinal implants, 5) the future of 3D printing in neurosurgical implantology. There were 5 main neurosurgery subtopics in which 3D printing was used: “vascular neurosurgery” (31%), “skull, cranial neurosurgery” (22.4%), “neuro-oncology” (19.3%), “spine” (14.3%) and “others” (13%). The number of published articles has been steadily increasing by 11-33% annually. Conclusion: 3D printing has an enormous potential for clinical use and in the we will continue to observe its dynamic development. In neurosurgery 3D prints are currently most commonly used for didactic purposes as detailed anatomical models, for training residents and young surgeons and by specialists for the simulation of complex or innovative surgeries. The future of the use of additive 3D printing in neurosurgery lies in the biological 3D printing, the creation of artifcial organs and the development of biological implants in tissue engineering.

Opis:

Purpose: Many printers are tempting at low prices, but later their accuracy turns out to be insufficient. The study has included checking the accuracy of printing and reproducing details of 3D printers used in dental technology and dentistry such as MultiJet Printing (ProJet MP3000, 3D Systems) and Fused Deposition Modelling (Inspire S2000, Tiertime). Design/methodology/approach: The 3D prints were created from scans of the maxillary gypsum model with the loss of left premolar. In the test, objects were set to the X and Y-axis. In order to check the dimensional differences after printing, scans of the printed models were superimposed on scans of the plaster model in the GOM Inspect V8 SR1 (Braunschweig, Germany). The focus was on the distance of scans from each other and a deviation map was created for each object. Findings: The average absolute value of deviations for each of models were equalled: FDM- for X-axis 0.06 ± 0.04 mm, for Y-axis 0.07 ± 0.04 mm; MJP- for X-axis- 0.04 ± 0.02 mm, for Y-axis- 0.06 ± 0.02 mm. A chart of arithmetic averages calculated for each tooth for the best printouts in each series show that higher deviation values exist in case of FDM printout. The models printed in the X-axis have smaller values of deviations from those printed in the Y-axis. Practical implications: MultiJet Printing technology can be used to create more precise models than the FDM, but these printouts meet the requirements of dimensional accuracy too. Originality/value: CAD / CAM technology in the future will exist in every dental technology laboratory so it is important to be aware of the way the 3D printers works. By paying attention to the quality of detail reproduction, a Dental Technician is able to choose the best 3D printer for them.

Opis:

Purpose This study focuses on determining the best possible structure of the orthosis made with FDM 3D printing technology. To produce the samples, a thermoplastic PLA material was selected that met the conditions of biodegradability, biocompatibility and non-toxicity. The samples produced were subjected to a tensile strength test and corrosion resistance. Design/methodology/approach Studies based on FEM analysis were carried out using the advanced engineering software CAE - Inventor. The samples were designed in the CAD system, while the G-Code path was generated using the PrusaSlicer 2.5.0 program dedicated to the Prusa i3 MK3S+ printer, which was used to create the models. Surface morphology observations of PLA were carried out with a Zeiss SUPRA 35 scanning electron microscope (SEM). The static tensile test was performed on the Zwick/Roell z100 device based on the PN-EN ISO 527:1 standard. Electrochemical corrosion tests were carried out using the Autolab PGSTAT302N Multi BA potentiostat in Ringer solution at a temperature of 37ºC. Findings The research allowed the appropriate structure of the orthosis made of PLA polymer material using 3D FDM printing technology. The static tensile test, SEM and corrosion tests confirmed the correct application of this material for the selected purpose. It was possible to determine that samples with holes of 10 mm had the highest strength properties. Due to the tensile tests, the average tensile strength of those samples was around 61 MPa. The corrosion parameters of PLA were determined using Tafel analysis. Research limitations/implications The research methodology proposed in work can be used to study other biomedical materials. The results presented can be the basis for further tests in order to search for the best orthopaedic stabiliser. Originality/value The innovative part of the article are three different versions of structures intended for making orthoses used in medicine.

Opis:

The paper presents an innovative method of creating the layered castings. The innovation relies on application the 3D printing insert obtaining in SLM (selective laser melting) method. This type of scaffold insert made from pure Ti powder, was placed into mould cavity directly before pouring by grey cast iron. In result of used method was obtained grey cast iron casting with surface layer reinforced by titanium carbides. In range of studies were carried out metallographic researches using light microscope and scanning electron microscope, microhardness measurements and abrasive wear resistance. On the basis of obtaining results was stated that there is a possibility of reinforcing surface layer of the grey cast iron casting by using 3D printing scaffold insert in the method of mould cavity preparation. Moreover there was a local increase in hardness and abrasive wear resistance in spite of the precipitation of titanium carbides in surface layer of grey cast iron. While the usable properties of composite surface layer obtained in result of use of the method presented in the paper, strongly depend of dimensions of scaffold insert, mainly parameters Re and Ri.

This paper presents the use of 3D printing and discusses two types of materials used in 3D printing, i.e. ABS (Acrylonitrile Butadiene Styrene) and PLA (Polylactide). Next, it presents the thermovisual measurementscarried out on 3D printed samples (FDM method - fused deposition modelling) of these materials. The temperature zones that occurred during printing were determined. The geometrical dimensions of samples from the same material that were printed under different conditions were compared. The height of the printed object has a large influence on temperature distribution on its surface and the printing time does not differ significantly when printing with PLA or ABS.

Computational intelligence (CI) can adopt/optimize important principles in the workflow of 3D printing. This article aims to examine to what extent the current possibilities for using CI in the development of 3D printing and reverse engineering are being used, and where there are still reserves in this area. Methodology: A literature review is followed by own research on CI-based solutions. Results: Two ANNs solving the most common problems are presented. Conclusions: CI can effectively support 3D printing and reverse engineering especially during the transition to Industry 4.0. Wider implementation of CI solutions can accelerate and integrate the development of innovative technologies based on 3D scanning, 3D printing, and reverse engineering. Analyzing data, gathering experience, and transforming it into knowledge can be done faster and more efficiently, but requires a conscious application and proper targeting.

However, this requires knowledge of the geometrical relationships of a threaded itself and the strength of materials from which the screw-threaded joint is made. Thanks to the development of research models and conducting tests related to dimensional accuracy and surface roughness, it was possible to test the models made by MEX process of ABS-M30, PLA, ABS, PETG materials, and PolyJet process from RGD720 polymer material.In the case of measurements carried out on the MarSurf XC20 system, the internal and external thread profile was obtained.Measurements of the surface roughness of the printed models were made using the Taylor Hobson TalyScan 150 profilometer. Based on the obtained surface, following the ISO 25178-2 standard, selected parameters were determined.

The study aimed to develop a system supporting technological process planning for machining and 3D printing. Such a system should function similarly to the way human experts act in their fields of expertise and should be capable of gathering the necessary knowledge, analysing data, and drawing conclusions to solve problems. This could be done by utilising artificial intelligence (AI) methods available within such systems. The study proved the usefulness of AI methods and their significant effectiveness in supporting technological process planning. The purpose of this article is to show an intelligent system that includes knowledge, models, and procedures supporting the company’s employees as part of machining and 3D printing. Few works are combining these two types of processing. Nowadays, however, these two types of processing overlap each other into a common concept of hybrid processing. Therefore, in the opinion of the authors, such a comprehensive system is necessary. The system-embedded knowledge takes the form of neural networks, decision trees, and facts. The system is presented using the example of a real enterprise. The intelligent expert system is intended for process engineers who have not yet gathered sufficient experience in technological-process planning, or who have just begun their work in a given production enterprise and are not very familiar with its machinery and other means of production.

Opis:

The paper presents a synthetic characterization of modern methods of manufacturing or regenerating machine elements. Considered methods are machining and additive methods, in particular 3D printing in the FDM/FFF technique. For the study, the authors made samples of the holder bracket using selected methods. Samples made by machining operations, 3D printing with various filling were tested. The paper contains a technical and economic analysis of the production of a holder bracket using the discussed methods. The dynamics of steel and FDM/FFF printed samples were also assessed by determining their resonance curves. The vibration magnification fac-tors were analyzed - the quotient of the vibration amplitudes in the resonance to the static deformations that occurred under the influence of the constant force and the location of the vibration resonances - the natural frequencies for individual vibration modes. The study's main objective is to assess the possibility of emergency changing the manufacturing technology of selected machine components. The authors were interested in partially replacing costly and not environmentally friendly milling with 3D printing. Machine elements can be manufactured by printing in classical machine building and emergency conditions to replace a damaged component temporarily (e.g., on a ship, for the time of arrival at a port or shipyard). The main assumption guiding the authors during the preparation of this publication was the analysis of the possibility of using the production of "ad hoc" prepared spare parts and their use in the event of a lack of access to parts made of the intended materials.

The aim of the work was to develop a computer program that allows identification of polymer materials that are used in 3D printing technology. The computer program was made using the algorithm that concerns the method of thermal polymer degradation. Filament samples were prepared for this purpose and then set on fire. The collected data on the flammability of polymers was used in an algorithm that can make a decision to identify the name of the polymer. The software can be used to identify polymer prints used for 3D printing technology. The computer program supports the process of recycling plastics and supports ecological work.

Opis:

The application of 3D printers significantly improves the process of producing foundry patterns in comparison to traditional methods of their production. It should be noted that the quality of the surface texture of the foundry pattern is crucial because it affects the quality of the casting mold and eventually the finished casting. In most studies, the surface texture is examined by analyzing the 2D or 3D roughness parameters. This is a certain limitation because, in the case of 3D printing, the influence of technological parameters is more visible for irregularities of a longer range, such as surface waviness. In the paper, the influence of the 3D printing layer thickness on the formation of waviness of the surface of casting patterns was analyzed. Three 3D printers, differing in terms of printing technology and printing material, were tested: PJM (PolyJet Matrix), FDM (fused deposition modeling) and SLS (selective laser sintering). In addition, the surface waviness of patterns manufactured with traditional methods was analyzed. Surface waviness has been measured using the Form Talysurf PGI 1200 measuring system. Preliminary results of the research showed that the layer thickness significantly influences the values of waviness parameters of the surface in the casting patterns made with FDM, PJM and SLS additive technologies. The research results indicated that the smallest surface waviness as defined by parameters Wa, Wq and Wt was obtained for patterns printed using the PJM technology, while the highest was noted when using the FDM technology.

Opis:

Technologia drukowania przestrzennego FDM umożliwia zobrazowanie wielu zagadnień technicznych przez wytworzenie modelu analizowanego obiektu bezpośrednio na zajęciach dydaktycznych. Drukarkę trójwymiarową może wykorzystać każda dziedzina wiedzy: od biologii (drukowanie modeli narządów), po architekturę (tworzenie skomplikowanych makiet). Już sama drukarka jest świetnym narzędziem, które samo w sobie jest ciekawe dla wielu kierunków. Studenci mogą nauczyć się dzięki niej programowania procesorów opartych na ATMEDZE, mogą przygotowywać nowe programy sterujące drukarką, projektować grafikę 3D na komputerach a uzyskane rezultaty drukować na zestawach drukarek. Ponadto każdą drukarkę można dowolnie ulepszać wg. własnych potrzeb - od zmiany czy przeniesienia napędu po wymienne ekstrudery - mechanizmy tłoczące tworzywa [1, 4].
An interesting example of a student's project was presented. Printing technology spatial FDM laboratory classes allows imaging of many technical issues by producing a model of the analyzed object directly in the classroom teaching. Three-dimensional printer can use virtually every branch of science: biology (print models of organs), and architecture (the creation of complex mock-ups). Even the printer is a great tool, which in itself is interesting for a number of directions.

Opis:

The article deals with the problem of designing conical gears with a curved line contour. The contour of the tooth flank is described by means of a helix and involutions. In the work, a conical gear designed to drive of the lower limb rehabilitation exoskeleton has analysed. Parameters of the conical gearbox have been adapted to design requirements of the exoskeleton. Gear wheels were made with ABS material using 3D printing technique. The article presents the results of strength calculations obtained using the method classical design of the gear wheals described in the norm ISO 6336-1996. In the strength calculations, bending and contact stresses were taken into account. Creating the contour of gears was aided through the gearbox wizard available in Inventor program. The work contains the results of a static tensile test of the material from which the gear wheels were made. In experimental and numerical studies, the orthotropy of the material used was taken into account. The orthogonal values of the Young’s modulus, the Poisson’s ratio and the Kirchhoff’s modulus were determined. The publication also includes partial results of fatigue tests in the area of normal stresses. In the research used to finite element method (FEM), determine of internal loads in the gear. A structure of the FEM model is described in detail. Maximum values of contact pressures determined by use to FEM models have been compared with the results obtained on the basis of Hertz’s formulas. The article presents basic geometrical and strength parameters of the designed gear. The work demonstrates the validity of the material models used. Limitations in the application of the classic method of calculating conical gears made of orthotropic materials have been indicated. The results of analytical and numerical calculations are presented in tabular and graphical form.

Opis:

Purpose: Analysis and the review of 3D scanning methods, methods of combining 3D scans and tables available on the market (rotary, tilt and turn) as non-destructive testing systems of polymer materials. As the problem of deformation testing of elements produced by 3D printing is relatively novel, so far a small number of publications on this subject have been observed in terms of current solutions in the area of methodology and devices. Design/methodology/approach: 3D print samples have been prepared using MultiJet Printing (MJP), also called PolyJet Printing. The first sample was left in a UV oven and the second one in a dark cabinet, without access to sunlight (standard conditions 23/50 as described in ISO 554:1976). Non-contact structured blue light 3D metrology grade scanner was used to capture the entire part geometry for inspection. A comparison of subsequent scans after postcuring with reference scans after printing can indicate dimensional changes. The resulting scans are detailed enough to monitor shape and size changes over time. Findings: Universal 3D printing model beneficial in distortion analysis has been proposed. The method of evaluating 3D print distortions was verified using a metrology class 3D scanner. The results of this study show that deformations are declining through time to near the same values, the only difference is the rate of change of dimensions. Practical implications: Due to popularity and lower cost of polymer 3D printing, in comparison to metal 3D printing, an initial attempt to analyse the distortion of the locally melted substrate was done using MultiJet 3D printing with photopolymer material. The universal 3D print test part was proposed for verification of 3D printing deformations. Finally, the framework for the determination of 3D printing distortions is presented, taking into account the influence of UV postcuring. Originality/value: Analysis of a method to measure 3D printing distortions using a metrology grade 3D scanner is presented in the paper. Recently, this matter is becoming more and more important because many prototypes are increasingly produced by 3D printing and 3D printing distortions may cause many difficulties during the manufacturing and assembly process.

Opis:

A successful approach widely used in materials science to adapt approved materials to specific applications is to design their surface properties. A main challenge in this area is the development of processing routes enabling for a simple but efficient surface design of complex shaped geometries. Against this background, this work aimed at the implementation of self-assembly principles for surface functionalization of 3D-printed poly(lactic-co-glycolic acid) (PLGA)-based constructs with macro- and microporous geometries via precision extruding deposition. Methods: Three-component melts from PLGA, CaCO3 and amphiphilic polymers (poly(2-oxazoline) block copolymer) were printed and their bulk and surface properties were studied. Results: Melts with up to 30 mass % of CaCO3 could be successfully printed with homogeneously distributed mineral particles. PLGA degradation during the printing process was temperature and time dependent: the molecular weight reached 10 to 15% of the initial values after ca. 120 min of heat exposure. Filament surfaces from melts containing CaCO3 show an increasing microroughness along with increasing CaCO3 content. Surface roughness and amphiphilic polymer content improve scaffold wettability with both factors showing synergistic effects. The CaCO3 content of the melts affected the inner filament structure during in vitro degradation in PBS, resulting in a homogeneous mineral particle-associated microporosity for mineral contents of 20 mass % and above. Conclusions: These results provide novel insights into the behavior of three-component melts from PLGA, CaCO3 and amphiphilic polymers during precision extruding deposition and show for the first time that self-assembly processes can be used to tailor scaffolds surface properties under such processing conditions.

Opis:

Selective laser sintering (SLS) is a type of laminating sintering technique, using CO₂ laser with (metal, polymer, and ceramic) powders. In this result, the flake SUS 316L was used to achieve a high porous product, and compare to spherical type. After SLS, the porosity of flake-type sample with 34% was quite higher than that of the spherical-type one that had only 11%. The surface roughness of the flake SLS sample were also investigated in both inner and surface parts. The results show that the deviation of the roughness of the surface part is about 64.40μm, while that of the internal one was about 117.65μm, which presents the containing of high porosity in the uneven surfaces. With the process using spherical powder, the sample was quite dense, however, some initial particles still remained as a result of less energy received at the beneath of the processing layer.

Opis:

Purpose In the Fused Filament Fabrication (FFF/FDM) technology, the multi-material manufacturing additive method is achieved by a single nozzle or multiple nozzles working simultaneously with different materials. However, the adhesion between different materials at the boundary interface in FDM multi-material printing is a limiting factor. These studies are concerned with improving and study the adhesion between two polymers. Design/methodology/approach Due to the numerous applications and possibilities of 3D printed objects, combining different materials has become a subject of interest. PLA is an alternative to the use of petrochemical-based polymers. Thermoplastic Polyurethane is a flexible material that can achieve different characteristics when combined with a rigid filament, such as PLA. To improve the adhesion between PLA and TPU in multi-material FFF/FDM, we propose the comparison of different processes: post-processing with acetone immersion, surface activation during printing with Acetone, surface activation during printing with tetrahydrofuran, post-processing annealing, and connection of printed parts with tetrahydrofuran. Findings Modifying the 3D printing process improved the quality of the adhesive bond between the two different polymers. Activation of the surface with THF is the treatment method recommended by the authors due to the low impact on the deformation/degradation of the object. Research limitations/implications In the study, adhesion was considered in relation to the circular pattern of surface development. Further analysis should include other surface development patterns and changes in printing parameters, e.g. process temperatures and layer application speed. Practical implications 3D printing with multi-materials, such as PLA biopolymer and thermoplastic polyurethane, allows for the creation of flexible connections. The strengthening of the biopolymer broadens the possibilities of using polylactide. Examples of applications include: automotive (elements, where flexible TPU absorbs vibrations and protects PLA from cracking), medicine (prostheses with flexible elements ensuring mobility in the joints). Originality/value Multi-material printing is a new trend in 3D printing research, and this research is aimed at promoting the use and expanding the possibilities of using PLA biopolymer.

Opis:

Nowadays, the optimization of energy consumption and resources is one of the most urgent topics in worldwide industry. The energy consumption monitoring and control in various multiphase flow industrial applications, where a proper flow characteristic and an optimal phase mixture control is crucial, is hard to perform due to the physical and chemical complexity of the processes. The Electrical Capacitance Tomography (ECT) is one of the relatively cheap non-invasive measurement methods that can help in the monitoring and control of optimal energy and resources dozing in industrial processes. ECT diagnostics systems use unique sensors that can non-intrusively detect spatial capacitance changes caused by spatial changes in the electrical permittivity of industrial process components. One of the latest ECT extensions is a three-dimensional measurement strategy that uses a multilayer structure of the capacitance sensor. In this paper, the authors propose a novel approach to the 3D ECT sensors fabrication process that uses 3D computer modelling and 3D printing to easily get any sensor shape, electrode layout, scale and shielding strategy. This study compares the measurement abilities of a 3D ECT sensor fabricated using a traditional hand-made technique with the 3D printed device. The results have proven the potential of the new 3D print-based sensor regarding its significant fabrication time reduction as well as the improvement of the overall 3D ECT sensor measurement accuracy and stability.

Opis:

The manufacturing of machine parts with additive methods (AM) is of significant importance in modern industry. The development of 3D printers and all 3D printing technology is impressive. The ability to make parts quickly and relatively cheaply with AM gives excellent opportunities in terms of e.g., shortening the production preparation time. Proper selection of printing parameters allows for a significant reduction of printing time and production costs. Unfortunately, this has different consequences. Due to the course of the printing process and the parameters that can be set, the same product produced with different parameters has different mechanical properties - mainly different strength. This paper presents the impact of 3D printing parameters on the strength of manufactured parts. Strength tests were carried out on samples made in accordance with DIN EN ISO 527-1:2019. The samples were printed in technology FDM from three different materials, i.e. PLA (completely biodegradable), PETG (recycled material), and Smart ABS (material with minimal shrinkage). The tested samples were made in three levels of print filling - 10%, 30%, and 60% and with different types of filling - line, mesh, and honeycomb. A series of static tensile tests were carried out to determine the strength of the samples produced with different printing parameters. Thanks to the obtained test results, it is possible to select the optimal printing parameters depending on the forecast load of the manufactured parts.

Opis:

The article presents the results of tests of 17-4PH steel fabricated by means of the method consisting in laser additive manufacturing (LAM) – direct metal laser sintering (DMLS). This grade of steel is characterized by excellent stress corrosion resistance in the first place and is applied as construction material in chemical, aircraft, medical or mould making industry. 3D metal printing is a relatively new method enabling significant change of structural properties of these materials at printing parameters predetermined by printers manufacturer for ”offline” printing mode. In order to achieve this goal, the authors have carried out the analysis of chemical composition, SEM tests and the tests of products surface rough-ness. Furthermore the products have been subjected to X-ray analysis by means of computed tomography (X-ray CT). Structural discontinuities have been found in upper layer and inside printouts subjected to tests.

Opis:

A short literature review was undertaken in terms of the structure, properties and applications of polymers, including those commonly used in 3D printing. The research part included the structural and thermal analysis of polylactide (PLA), which is an example of an extensively used polymer in the developing 3D technology. Special attention was paid to the comparison of structure and thermal stability of two different (from various producers) polylactide samples. The research, involving such analytical methods as infrared spectroscopy (FTIR) and diffuse reflectance infrared spectroscopy (DRIFT), allowed the comparison of the structure of the two PLA samples considered. The determination of the temperature range in which changes related to PLA thermodestruction occur was a result of the performed thermoanalytical research (DRIFT, TG-DTG). Thermal studies also allowed to establish the temperature range in which the material does not yet degrade, which is important in the context of future planned research work on polylactide modification to obtain the improvement of the thermal and mechanical properties of PLA-based materials. This research area will be described in the second part of the publication.

Opis:

The application of 3D printing technology has been relatively slow in the fashion industry. Both in the fashion industry and in 3D printing, the material used plays a very important role. In this direction, thermoplastic polyurethane (TPU) is one material that has started to grab the attention of researchers, producers, and customers. While many have studied 3D printing technology using thermoplastic polyurethane material in the fashion industry from different perspectives, fewer researchers have addressed the actual adoption of thermoplastic polyurethane based 3D printing in the fashion industry. Thus, the present research has been focused to propose an adoption model for thermoplastic polyurethane based 3D-printed fashion clothes. Factor analysis was conducted to find and analyse the most relevant factors. Further exploratory factor analysis was conducted to test the proposed model. The study proposed a model for adoption based on four factors: motivation to buy, customer attitude, and the challenges and benefits associated with the adoption of thermoplastic polyurethane based 3-D printed fashion clothes.

The Fourth Industrial Revolution, also known as Industry 4.0, is about connecting the physical world with the virtual world in real-time. With the advent of the Fourth Industrial Revolution, manufacturing companies are introducing a number of solutions that increase productivity and personalize finished products in line with the idea of Industry 4.0. The application of, among others, the following: 3D printing, the Internet of Things, Big Data, cyber-physical systems, computing clouds, robots (collaborating and mobile), Radio-frequency identification systems, and also quality control and reverse engineering systems, is becoming popular. There are still not enough studies and analyses connected with the Polish 3D printing market, and also attempt to determine the attitude of those studies and analyses to the implementation of the Industry 4.0 conception. In connection with what is stated above, the principal objective of this paper is to determine the directions of the 3D printing industry development. In this publication, it is as well the survey respondents’ opinions relevant to opportunities and threats connected with the implementation of the Industry 4.0 conception in an enterprise are presented. The survey was conducted on a group of 100 enterprises and scientific research institutes in Poland, offering and/or applying additive technologies.

Opis:

The densification behavior of H13 tool steel powder by dual speed laser scanning strategy have been characterized for selective laser melting process, one of powder bed fusion based metal 3d printing. Under limited given laser power, the laser re-melting increases the relative density and hardness of H13 tool steel with closing pores. The single melt-pool analysis shows that the pores are located on top area of melt pool when the scanning speed is over 400 mm/s while the low scanning speed of 200 mm/s generates pores beneath the melt pool in the form of keyhole mode with the high energy input from the laser. With the second laser scanning, the pores on top area of melt pools are efficiently closed with proper dual combination of scan speed. However pores located beneath the melt pools could not be removed by second laser scanning. When each layer of 3d printing are re-melted, the relative density and hardness are improved for most dual combination of scanning. Among the scan speed combination, the 600 mm/s by 400 mm/s leads to the highest relative density, 99.94% with hardness of 53.5 HRC. This densification characterization with H13 tool steel laser re-melting can be efficiently applied for tool steel component manufacturing via metal 3d printing.

Opis:

Incremental sheet forming is used to form metal sheets on massive dies. However, the waste and time lost due to the machining of dies can be a problem for both companies and the environment. Additive manufacturing is thus a potential alternative to classical machining of dies, but these complex geometries could be challenging for classical layer-by-layer 3D printing techniques. This paper will present an innovative process based on a 3D printing technology using 3-axis systems and a pellet extruder combined with the generation of non-planar trajectories in order to achieve good surface quality. PLA-based parts were realised to evaluate surface quality and mechanical properties. With such a technique, the obtained 3D printed parts were closer to the expected CAD geometries and smoother top surfaces were obtained. These improvements have been made possible through the development of specific post-processors and printing strategies in order to replicate the behaviour of a 3D printer at a larger scale, which is a current challenge in robotic 3D printing.

The aim of the present article is the assessment of technical shear resistance (technological shear) of orthopedic screw made of titanium alloy Ti6Al4V, produced using incremental technology in the process of 3D printing process. The first part of the work presents incremental techniques in production engineering. The second part of the present work contains a specification of the 3D printing process of samples as well as the description of the used material. The fundamental part of the article is composed out of endurance tests for orthopaedic screws as well as the analysis of the obtained results and conclusions. The method of incremental production SLM using SLM 280HL metal printer was used during the technological process. The resistance tests were performed using ZWICK/ROELL Z150 machines. Identical endurance trials were performed for monolithic bars made of titanium alloys (of bar core size ) made on a wire electric discharge machine Sodick SL600Q for comparative purposes. The obtained test results enabled comparative assessment of the value of shear resistance Rt in the conditions of technological shear. According to the performed tests, the shear resistance Rt of orthopaedic screws is nearly 33% lower than of monolithic bars of the same core size.

Opis:

This article presents a comparison of test results from two models of anti-vibration systems (I and II) made employing MJF 3D printing technology and two different materials. The research included laboratory tests and numerical simulations, assuming a linear nature of the mechanical properties for the materials and models of structures. The aim of this research was to assess the consistency between laboratory test and numerical simulation results. In addition, evaluation of the suitability of using MJF technology to produce antivibration systems was conducted. During the laboratory tests, the response of the two models of structures to vibrations generated by an exciter was recorded using a high-speed camera. Subsequent image analysis was performed using the MOVIAS Neo software. The obtained values of vibration displacements and resonant frequencies were used to validate the numerical model created in the Simcenter Femap software. Relative differences between the values of resonant frequencies obtained experimentally and through simulations were determined. In the case of the structural model I, creating its numerical model without considering the nonlinearity of mechanical parameters was found to be unjustified. The comparison of the displacements determined during numerical simulations showed relative differences of less than 16% for both models in relation to the laboratory test results. This comparison result indicates a satisfactory accuracy in simulating this parameter. An assessment of the quality and accuracy of MJF technology-produced prints, led to the conclusion that due to the formation of internal stresses during the print creation, the use of “soft” materials in this technology is problematic.

Opis:

This paper concerns the problem of intellectual property law in the context of 3D printing technology, that becomes more popular. In the age of universal digital communication and constant growth of importance of digital information goods, intellectual property is becoming a cause of dispute between different social groups. This is partly because of the impact of informal institutions formed during development of the Internet and social movements postulating free access to information (including the digital information goods). Other important issue is also the problem of public copyright infringement in order to achieve private benefits. Conflicts concerning enforcement of the intellectual property right are related to substantially all of the digitized content: written word, music, movies and software. On one hand the decrease of the costs of copying equipment, allows an average consumer to buy such a printer. On the other hand the increase of the Internet bandwidth makes this phenomenon more significant. 3D printing technology is the next stage of self-production process. This technology goes beyond the abstract world of information to a real world of physical goods. Thus, the violation of property rights refers now not only to information goods, but also to physical products. The authors put the thesis that the development of 3D printing technology will intensify the conflicts and will increase the number of abuses in area of intellectual property law. In this article the authors discuss the development of 3D printing technology, which originally was connected only with so-called rapid prototyping in the product development process. However, with cheaper equipment, this technology became available to a larger number of users who have used it to make the final products. This process was simultaneous to research projects conducted by academic institutions such as RepRap and Fab@Home. The main goal of RepRap project was to create self-replicating machine. The RepRap 3D printer allows to print more 3D printing devices. This project is regulated by copyleft licenses allowing to manipulate within the files with a legal authors permission. Extending the reflections on copyright issue the authors focused on the licenses that allow to share the projects files required for the creation of physical objects. Copyleft licenses are sometimes given illegally. Some of the project files contain elements that are under copyright restriction. This situation was discovered during the analysis of the content shared between users of 3D printers portals. This situation creates a great threat to the enterprises engaged in luxury goods because in this business the main value is the idea – the design. Easy replication provided by 3D printing technology enforces more effective copyright regulations or even modification of the form of distribution of items protected by law. The development of 3D printing technology will inevitably increase the number of conflicts and abu

Opis:

Opracowania dwuwymiarowe przedstawiające ukształtowanie terenu (np. w postaci mapy) nie oddają w całości charakteru obrazowanego obszaru. Przedsięwzięcia związane z planowaniem czy projektowaniem zdecydowanie korzystniej jest przedstawiać w przestrzeni trójwymiarowej. Wykorzystywane niegdyś stoły plastyczne, popularne zwłaszcza w zastosowaniach militarnych, są drogie i niewygodne do stosowania ze względu na duże rozmiary. Ponadto, są one modyfikowalne tylko w niewielkim stopniu i nie zapewniają takiej szczegółowości jak klasyczne mapy. Wraz z rozwojem nowoczesnych technik wytwarzania map plastycznych zwiększyło się spektrum możliwości opracowywania personalizowanych modeli przestrzennych otaczającej nas rzeczywistości, odwzorowanych w odpowiedniej skali w przestrzeni trójwymiarowej. Celem artykułu jest przedstawienie możliwości wykorzystania druku 3D do wizualizacji obszarów górskich. W ramach badań, na podstawie numerycznego modelu terenu (DTED 2 - digital terrain elevation data, którego dokładność szacowana jest na ± 30 m w płaszczyźnie poziomej i ± 20 m w płaszczyźnie pionowej), opracowano model fragmentu Tatr. Model ten opracowano w programach Global Mapper i Rhino 3D. Następnie został on wydrukowany na drukarce 3D z wykorzystaniem technologii FDM (Fused Deposition Modeling). Artykuł opisuje zasady opracowania takiego modelu oraz wady i zalety zaproponowanego rozwiązania.
Flat studies showing terrain (e.g. in form of maps) do not fully reflect its nature. Planning or design projects are definitely better represented in three-dimensional space. Previously used “sand tables”, especially popular in military applications, are expensive and uncomfortable to use due to their large size. In addition, they are modifiable only to a small extent and do not provide such accuracy as traditional maps. With the development of modern model relief techniques, a spectrum of the possibilities for development of customized spatial models (defined as models of the surrounding reality, mapped in the appropriate scale in three dimensions), has increased. The aim of this article is to present the possibilities of using 3D printing for the visualization of a mountain. Based on the digital terrain model (DTM), a model of a part of the Tatra Mountains was developed. It was established by DTM data processing and printing on a 3D printer using the FDM (Fused Deposition Modeling) technology. This article describes the principles for developing such a model and the advantages and disadvantages of the proposed solution.

Opis:

In recent years, a rapid increase in the use of three-dimensional (3D) printing technologies in medicine, especially in the manufacturing of the diagnostic models, can be observed. In some cases, there is a need to fabricate transparent models that allow visualization of internal structures of the object. Unfortunately, techniques used to manufacture such models are often very expensive and time-consuming. The above-mentioned issues were the motivation for developing a new method of fabrication transparent models for visualization of internal structures for planning surgical treatments. This paper presents the process of making transparent models using the newly developed method – the stacked layers method. In order to compare this new method and one of the most common 3D printing technologies – fused deposition modeling (FDM) – the models for two medical cases using both of these methods were fabricated. As a result of this work, it can be concluded that the stacked layers method provides faster and cheaper way of making transparent medical models. The main features of fabrication process that have a huge impact on quality of the models made by new method were pointed. The results of this study suggest that models fabricated with the use of this method can be useful as a diagnostic tool in medical applications for planning surgical treatments.

Opis:

This article analyzes the influence of layer height on the tensile strength of PLA specimens printed in the Fused Deposition Modeling (FDM) technology. The maximum breaking force of specimens with 30% and 100% infill density was determined at layer height of 0.05 mm, 0.1 mm, 0.2 mm and 0.3 mm. In the case of 30% infill, the highest value of the force was obtained for a layer with a height of 0.05 mm (which corresponds to 22.7 MPa), and for a 100% infill for a layer of 0.2 (which corresponds to 40 MPa). Over this layer height of 0.2 mm is the most poly-optimal due to the time prints and strength (which corresponds to 19.7 MPa).

Opis:

The article presents the results of tensile strength tests taking into account the influence of the printing nozzle diameter. The 3D printing method in FDM technology is described. The aim of the research was to investigate the effect of the printing nozzle diameter installed in the head. Samples printed with two types of filling were tested. The obtained results were summarized and compared. The printing time of the samples was compared with a diameter of each nozzle. Based on the strength tests, it can be concluded that the tensile strength of the samples made with the FDM printing technology is proportional to the used printing nozzle diameter.
W artykule przedstawiono wyniki badań wytrzymałościowych na rozciąganie z uwzględnieniem wpływu średnicy dyszy drukującej. Opisano metodę druku 3D w technologii FDM. Celem badań było zbadanie wpływu średnicy dyszy drukującej zainstalowanej w głowicy. Wykonano badania próbek wydrukowanych przy dwóch rodzajach wypełnienia. Otrzymane wyniki zostały zestawione i porównane. Porównany został czas wydruku próbek poszczególną średnicą dyszy. Na podstawie prób wytrzymałościowych można stwierdzić, że wytrzymałość na rozciąganie próbek wykonanych w technologii druku FDM jest proporcjonalna do zastosowanej średnicy dyszy drukującej.

Opis:

Despite the very rapid technological development, the general concept of mechanical devices has not changed. Still, the most common element of these devices are gears, whose range of use is very wide. There are both technological and historical considerations for the reconstruction of gears and other elements. In particular, this applies to spare parts for technical facilities that are not available on the market or service costs are too high. Contemporary reconstruction is called Reverse Engineering, which offers tools that allow transformation of an existing object through a virtual model into the final real product. Modern production engineering is based on innovative CAD – Computer Aided Designed design methods and computer-aided manufacturing technologies, CAM – Computer Aided Manufacturing. The rapid development of 3D CAD systems has led to the development of solutions to obtain the designed object, already at the development stage. Such a solution is the Rapid Prototyping method, designed for fast, precise and repeatable production of machine components. Widespread use and growing interest in the use of additive printing influenced the development of this technology. The purpose of the article is to present the practical application of the Reverse Engineering method and 3D printing in the reconstruction of gears. The object of research is the real gear, which has been reconstructed using Reverse Engineering and 3D printing. The article presents the basic assumptions of the methods used and the methodology for conducting reconstruction work. FDM (Fused Deposition Modeling) technology was used for the research. The results obtained are a real example of the practical application of the presented methods. At the same time, they create great opportunities for their wider use.

The article presents the results of static tests performed on the primary support structures of a TWISST-ter unmanned aircraft constructed using additive manufacturing techniques commonly known as 3D printing. The primary goal of the experiment was determining the material effort of the structure in order to assess the feasibility of such an engineering solution in terms of material mechanics. Considering the fact that the properties of 3D printed elements are not widely known, both destructive experimental methods and finite element methods were used. During the experimental trails, the ARAMIS deformation measurement system, based on digital three-dimensional image correlation, was used. The results of this experiment allowed for the calibration of the numerical model as achieving convergence with experimentally determined strain fields. This approach ensured the correctness of the numerical determined stress state. Based on the results of the study, the necessary design improvements were implemented and a general conclusion was formed regarding of the numerical analysis of structures made through 3D printing.

Opis:

In recent years, FDM technology (Fused Deposition Modelling) has become one of the most widely-used rapid prototyping methods for various applications. This method is based on fused fibre material deposition on a drop-down platform, which offers the opportunity to design and introduce new materials, including composites. The material most commonly used in FDM is ABS, followed by PC, PLA, PPSF, ULTEM9085 and mixtures thereof. Recently, work has been done on the possibility of applying ABS blends: steel powders, aluminium, or even wood ash. Unfortunately, most modern commercial systems are closed, preventing the use of any materials other than those of the manufacturer. For this reason, the Department of Manufacturing Systems (KSW) of AGH University of Science and Technology, Faculty of Mechanical Engineering And Robotics purchased a 3D printer with feeding material from trays reel, which allows for the use of other materials. In addition, a feedstock production system for the 3D printer has been developed and work has started on the creation of new composite materials utilising ceramics.
W ostatnich latach technologia FDM (Fused Deposition Modelling) stała się jedną z najszerzej i najczęściej stosowanych metod szybkiego prototypowania, stosowanych w różnych aplikacjach. Jest to metoda oparta na osadzaniu topionego włókna materiału na opuszczanej platformie, oferującej możliwość opracowywania i wprowadzania nowych materiałów, również kompozytowych. Materiałem najczęściej stosowanym w tej technologii jest ABS. jak również PC. PLA. PPSF. ULTEM9085 oraz ich mieszanki. W ostatnich latach pojawiły się prace nad możliwością zastosowania również mieszanek ABS - proszki stali, aluminium czy też np. pyłu drewnianego. Niestety większość nowoczesnych komercyjnych systemów jest zamkniętych, blokujących możliwość zastosowania innych materiałów niż producenta. Z tego powodu, w Katedrze Systemów Wytwarzania AGH, została zakupiona drukarka przestrzenna z podawaniem materiału z zasobników szpulowych, co umożliwia zastosowanie również innych materiałów. Dodatkowo, w ramach prac KSW, został opracowany system wytwarzania materiału wsadowego dla drukarki oraz rozpoczęto prace nad wytworzeniem nowych materiałów kompozytowych z wykorzystaniem ceramiki.

Opis:

Polymers are compounds that play a key role in the development of many fields of science, including emergency medicine. Currently, there are increasing requirements for biomedical polymers in terms of producing lighter and more ecological equipment. To meet these requirements, a composite material was developed: polylactide (PLA) with the addition of modifiers - basalt and silicon dioxide (SiO2). PLA was chosen as a biodegradable polymer that naturally decomposes in the environment. This is very important, regarding a large number of single-use materials made of microplastics polluting the environment. The samples were made by additive 3D printing and then immersed in swimming pool water, chlorine solution, and distilled water. FTIR analysis showed the influence of the environment on the intensity and shift of PLA absorption bands. Microscopic analysis provided information on surface morphology, roughness, and potential defects. Tribological and micromechanical tests showed that the additions of basalt and silica to the PLA material influenced the morphological structure and the average area of the wear trace, volumetric wear, and average coefficient of friction. In the presence of chlorine solution, distilled water, and pool water under real conditions, the SiO2 addition made the PLA material more resistant to abrasion, as compared to the basalt addition. However, additives did not significantly affect the PLA material hardness, and the samples with basalt turned out to be more resistant to deformation.

Risk analysis of personalized medical devices, such as prostheses, is a challenging task due to the complexity of technological and geometrical issues. The paper undertakes a process of risk analysis for upper limb prostheses for adult patients, individualized by 3D scanning and produced by additive manufacturing. The analysis was performed to systematize the process and its steps, as well as diagnose certain problems, in order to achieve future devices with correct fit and function, produced in as few iterations as possible. The Failure Mode and Effect Analysis of Process (PFMEA) method was used. In the results, main process risks were identified: the problems are mostly caused in stages, where operator’s decision or activity is to be performed, regarding socket length, offset and suitable lining. The main prevention activities were determined – human involvement in the decision process should be minimal and the intelligent models should be adjustable to as many patient cases as possible. In consequence, future steps for process optimization were determined – larger base of patient cases is necessary to acquire and study, to gather data for model and process improvement.

Purpose: The aim of the work is to execute measurements of digital dental models taken by scanning prosthetic impressions using the engineering CAD software and finding dimensional differences and scale factor for precise reproduction of patient tooth dimensions. Design/methodology/approach: Tests were carried out involving the execution of 3 series of impressions for selected impression materials, which were then scanned using two types of prosthetic scanners. Gypsum models based on mentioned impressions were scanned and dimensionally compared with impression-based digital models. Benchmark impressions were also performed in order to verify the obtained results and determine the correction factor for dimensions. The dimensional differences between impression groups were calculated by using Engineering CAD software. Findings: It was found, that compared to the base model, the digital model has a smaller volume than the object being mapped, the digital models based directly on the impression should be 0.09 - 0.12% rescaled to match the dimensions of the base model. Research limitations/implications: It is necessary to perform a practical verification of the results achieved and apply the determined coefficient in practice by creating working models using precise devices such as a 3D SLA printer and verify their results with intraoral scanner based models. Practical implications: This test will allow making precise working models using a 3D printer, allowing finally to perform, for example, implant-based bridges directly from the level of implants, using the masses described in the study. Originality/value: The comparative studies of polyvinyl siloxane and alignate impression materials were carried out in order to measure dimensional differences between working models made directly from the impression and gypsum models and compared with pattern, which allowed to determine the expansion coefficient, which will allow to work in 3D printing technology with close representation of real situation in the patient's oral cavity, which is particularly important when performing full arch bridges and extensive work on implants, including direct implants. The work has practical applications for both dental engineers and dentists performing advanced prosthetic work.

Opis:

Celem przeglądu literatury jest wyznaczenie zakresu zastosowań wydruków 3D uzyskiwanych w technologii druku przyrostowego CJP oraz 3DP w obrębie nauk przyrodniczych, ze szczególnym naciskiem na wykorzystanie ich do planowania zabiegów ortopedycznych o wysokim stopniu komplikacji. Badania nad stosowaną metodą będą związane w ścisłej korelacji z aspektem finansowym. Badacze przyjmują za aksjomat fakt, iż głównym nabywcą będzie jednostka poddana leczeniu (pacjent), odbiorcą natomiast podmiot lub osoba udzielająca jej pomocy (lekarz). Przy wykorzystaniu dostępnych otwarto-źródłowych rozwiązań programowych oraz odpowiedniej metodzie obróbki wyników badań CT, bazującej na algorytmie filtrów dla plików RAW, udało się uzyskać pierwsze relatywnie satysfakcjonujące efekty. Pozwalają one na prawie całkowite wykluczenie ludzkiej pracy z jednego z najtrudniejszych i najbardziej czasochłonnych procesów – jaki wpisz. Koszt całkowity (brutto) komercyjnego wydruku 3D, z uwzględnieniem wszystkich procesów produkcyjnych oraz poprodukcyjnych, jest średnio do 50% niższy od stawek komercyjnych dla modelu (os coxae) miednicy wraz z „os femoris” kością udową nieprzekraczającą długości 20 cm. Jest to efekt ”względnie pozytywny”. Mimo niewątpliwego sukcesu w zakresie kosztów druku 3D, będzie się dążyć do zmniejszenia kosztu wydruku o kolejne 30% (liczone od kwoty bazowej) poprzez wprowadzanie maszynowej obróbki oraz automatyzacji zadań oraz stosowanie innych metod druku. Zastosowanie wydruków 3D przy szeroko pojętym planowaniu zabiegów ortopedycznych, pozwala na znaczące zmniejszenie użycia instrumentarium oraz czasu zabiegu, w odniesieniu do przeprowadzonych podobnych działań, nieuwzględniających w swoim zakresie wydruku 3D.
The purpose of the literature review is to determine the scope of 3D printing, also known as RP (Rapid Prototyping) applications in manufacturing medical model based on CJP (Collor Jet Printing) technology, with emphasis on the use in orthopedic surgery planning. The research of the presented method will be focused on the financial aspect. Researchers accept as axiomatic fact that the main buyer of the MRP (Medical Rapid Prototyping) structure will be the patient while the recipient will be the doctor or surgeon that provides the operation. Using available open-source software solutions and suitable method for the treatment of CT (Computed Tomography) scans based on filtering RAW files managed we to get the best or relatively good results allowing to exclude a human work from one of the most difficult and time-consuming processes. Total cost of 3D printings including all production processes and post-productions are about 50% lower than commercial rates (on free market) for the model of: “oscoxae” including "osfemoris" (femur length not exceeding 20 cm). In our opinion it’s "relatively positive" effect. Despite the success in the field of lowering the cost of 3D prints our work is still focused on reducing it (at least up to another 30%) by using automated-machine processing and tasks automation, as well as using another printing methods. Using 3D printings as a tools to help plan complex orthopedic surgeries make possible to extremely reduce the time of using instrumentation and the treatment time (comparing to similar surgeries carried out without using 3D printings).

Opis:

Nowadays, it is necessary to develop a conceptual framework for analysing the relationship between the implementation of Additive Manufacturing (AM) and Supply Chain Management (SCM). In this context, a gap in the research has been observed in the new approach to designing the importance of AM in SCM. The main contribution of this paper, therefore, is a new framework to formulate the role in adopting AM in SCM. The research methodology is based on detailed literature studies of AM in relation to the SCM process within a manufacturing company, as well on a case study, namely the COWAN GmbH manufacturing company who specialise in producing homewares for motorhome enthusiasts. As highlighted in the state-of-the-art analysis, no work, currently available, supports all the features presented.

Opis:

Additive manufacturing in recent years has become one of the fastest growing technologies. The increasing availability of 3D printing devices means that every year more and more devices of this type are found in the homes of ordinary people. Unfortunately, air pollution is formed during the process. Their main types include Ultra Fine Particles (UFP) and Volatile Compounds (VOC). In the event of air flow restriction, these substances can accumulate in the room and then enter the organisms of people staying there. The article presents the main substances that have been identified in various studies available in literature. Health aspects and potential threats related to inhalation of substances contained in dusts and gases generated during the process are shown, taking into account the division into individual types of printing materials. The article also presents the differences between the research results for 3d printing from individual plastics among different authors and describes possible causes of discrepancies.

Introduction: Conjoined twins are identical twins with fused bodies, joined in utero. They are rare complications of monochorionic twinning. The purpose of this study is to describe the various types of conjoined twins, the role of imaging and recent advances aiding in their management. Material and methods: This was a twin institutional study involving 3 cases of conjoined twins diagnosed over a period of 6 years from 2010 to 2015. All the 3 cases were identified antenatally by ultrasound. Only one case was further evaluated by MRI. Results: Three cases of conjoined twins (cephalopagus, thoracopagus and omphalopagus) were accurately diagnosed on antenatal ultrasound. After detailed counseling of the parents and obtaining written consent, all the three cases of pregnancy were terminated. Delivery of the viable conjoined twins was achieved without any complications to the mothers, and all the three conjoined twins died after a few minutes. Conclusion: Ultrasound enables an early and accurate diagnosis of conjoined twins, which is vital for obstetric management. MRI is reserved for better tissue characterization. Termination of pregnancy when opted, should be done at an early stage as later stages are fraught with problems. Recent advances, such as 3D printing, may aid in surgical pre-planning, thereby enabling successful surgical separation of conjoined twins.
Wstęp: Bliźnięta nierozdzielone to bliźnięta jednojajowe zrośnięte ze sobą w życiu płodowym. Jest to rzadkie powikłanie wśród bliźniąt jednokosmówkowych. Celem niniejszej pracy było przedstawienie różnych rodzajów bliźniąt nierozdzielonych, a także omówienie roli badań obrazowych oraz nowych technologii usprawniających postępowanie w takich przypadkach. Materiał i metody: Badaniem, przeprowadzonym w dwóch ośrodkach, objęto trzy przypadki bliźniąt nierozdzielonych, zdiagnozowane w okresie 6 lat – od 2010 do 2015 roku. W każdym przypadku rozpoznanie ustalono w prenatalnym badaniu ultrasonograficznym. W jednym przypadku w toku dalszej diagnostyki przeprowadzono badanie metodą rezonansu magnetycznego. Wyniki: Prezentowane trzy przypadki bliźniąt nierozdzielonych (cephalopagus, thoracopagus i omphalopagus) zostały prawidłowo zidentyfikowane w prenatalnym badaniu ultrasonograficznym. Po szczegółowym omówieniu rozpoznania z rodzicami oraz otrzymaniu pisemnej zgody wszystkie ciąże terminowano. Poród żywych bliźniąt był niepowikłany dla matek i we wszystkich przypadkach dzieci zmarły kilka minut po urodzeniu. Wnioski: Badanie ultrasonograficzne umożliwia wczesne i trafne rozpoznanie bliźniąt nierozdzielonych, co jest kluczowe w położnictwie. Rezonans magnetyczny stosuje się w celu bardziej szczegółowego scharakteryzowania tkanek. W przypadku decyzji o terminacji ciąży odpowiednie postępowanie należy wdrożyć jak najwcześniej, ze względu na problemy, jakie mogą się pojawić w późniejszych etapach ciąży. Nowe technologie, jak druk trójwymiarowy, mogą być pomocne w planowaniu zabiegów chirurgicznych i umożliwiają tym samym skuteczne rozdzielenie bliźniąt.

Opis:

W pracy analizowano przydatność technologii druku 3D do konstrukcji podłoży antenowych o zadanej przenikalności elektrycznej. Parametr ten, jak wiadomo, ma silny wpływ na parametry anten planarnych. Zastosowanie druku 3D pozwala na dość swobodny dobór wartości przenikalności elektrycznej w granicach pomiędzy wartością dla powietrza i materiału litego. Dobór taki można realizować poprzez zmianę tworzywa wykorzystywanego do druku 3D oraz sposób wypełniania objętości podłoża. Wyniki symulacji i wstępnych pomiarów wskazują, że idea druku podłoży antenowych może być interesująca z konstrukcyjnego punktu widzenia. Przedmiotem opisanej w artykule pracy było wykonanie symulacji wybranych własności anten planarnych na podłożach drukowanych, a następnie realizacja pomiarów z wykorzystaniem wykonanych modeli laboratoryjnych. Porównanie otrzymanych wyników numerycznych z wartościami uzyskanymi w trakcie pomiarów jest źródłem informacji o stosowalności standardowych technik symulacyjnych w odniesieniu do podłoży drukowanych o dość skomplikowanej ażurowej strukturze.
The applicability of 3D print technologies for manufacturing of planar antenna substrates having tailored permittivity was considered in the work. The permittivity is known as a parameter that has strong influence on the planar antennae key parameters. The application of 3D print gives the possibility of changing this parameter in the range between its value for air up to the value for homogeneous solid material. The change can be achieved through the change of the filament material and the way of 3D print pattern. The preliminary results of simulations and measurements show that the idea of printing of planar antennae substrate may be interesting alternative from a design engineering point of view.

Opis:

Due to limited production numbers, using additive manufacturing for the production of railway components, is proving more economical. Furthermore, strict requirements regarding flammability properties, standardised in EN 45545-2, are applied on trains. This work focuses on the production of transparent components made of Polycarbonate via 3D-printing. The polymer was modified using different flame retardant agents and the influence of the printing parameters, especially the print density, was determined. Polylactic Acid was examined for comparison reasons only. The printed and modified polymers were tested exposing the samples to heat radiation, according to ISO 5660-1 using a Cone Calorimeter, and to a direct flame, according to UL 94. Processing and printing of the polymer causes thermal stress to the molecules. This may lead to a worsening of the flammability causing a decline of the properties compared to the native Polycarbonate. This was confirmed through both testing methods. Moreover, the additive and the print density both influence the flammability properties depending on the polymer type. In summary print parameters and additivation have to be carefully considered when it comes to the flammability properties of polymers.

Opis:

In the field of numerical research there are various approaches and methods for structures of porous materials modeling. The solution is the use of fractal models to develop the porous structure. In the case of modeling the geometry of natural (random) materials, there is a problem of compatibility of the FE model geometry and real one. This is a source of differences between the results of calculations and experimental ones. Application of 3D printing technology will allow to receive a real structure in a controlled manner, which exactly reflects the designed structure and is consistent with the geometry of the numerical model. An experimental research on the standard samples made of photopolymer resin using 3D printing technique was presented in the paper. The aim of the research was to determine the base material properties and, consequently, to select the constitutive model, which is necessary to carry out numerical analyses.

Opis:

In this study the scaffolds for nasal cartilages replacement were designed using a software called Rhino 3D v5.0. The software parameters considered for the design of scaffolds were chosen and the scaffolds were fabricated using Fused Deposition Modeling (FDM), a rapid prototyping technology, using poly(L-lactic acid) (PLLA) filament. The topographical properties of the scaffolds were calculated through 3D model simulation. The morphology of obtained scaffold was observed by Scanning Electron Microscopy (SEM). The biological properties, i.e. bioactivity of the scaffolds, were assessed in Simulated Body Fluid. On the basis of natural cartilages images the external shape of the scaffold was designed using the 3D modeling software. The FDM is a useful method in fabrication of 3D bioactive implants for cartilage tissue engineering. Thanks to the use of 3D modeling software, it is possible to prepare and manufacture artificial cartilage in a controlled manner. Artificial scaffold made of PLLA polymeric matrix may mimic natural one by shape, topography, geometry, pore size, and their distribution. In addition, it is possible to guarantee appropriately selected biological properties such as biocompatibility and high bioactivity of scaffolds, which was proved using scanning electron microscopy (SEM) analysis. The surface observation of the 3D printed scaffolds showed in vitro formation of apatite after immersion in the SBF. What is more, it is possible to match the scaffold not only to the large cavity but also individually to each patient.

This paper presents the results of experiments on metallization of plastic elements produced using 3D printing technology from the light-hardened resins. The obtained coatings were bimetallic (Cu/Ni). The first step of metallization was the electroless deposition of copper. The second one was electrodeposition of nickel on the previously prepared copper substrate. The parameters of 3D prints preparation and metallization processes were deeply investigated. The etching of plastics substrates and duration of electroless metallization of 3D prints by copper were analyzed. In the next step the influence of nickel electrodeposition time was investigated. The coating were analyzed by XRD method and morphology of surface was analyzed by scanning electron microscopy (SEM). The thickness of coatings was calculated based on mass differences and measured by using optical microscopy method. The optimal parameters for both processes were specified.

Opis:

Counteracting the social and educational exclusion of visually impaired people is an important issue in the area of knowledge transfer, also in the area of cultural heritage. Visually impaired people get to know the world in an organoleptic way, where the leading cognitive factor is touch. This type of cognitive method cannot be used in museology and historical architecture. Current attempts to solve this problem lead to the use of additive technology understood as 3D printing. The paper presents a modified procedure for obtaining digital 3D models with the use of Autodesk Inventor version 2021, dedicated to creating scalable replicas of architectural objects using additive technology. The applied procedure uses the decomposition of the object into its components and the acquisition of data from terrestrial 3D laser scanning (FARO Focus 3D scanner, Faro Scene software). Printing in the Fused Filament Fabrication technology of a designed minaret representing the architecture of the Timuridian period (minaret of the Ulugh Beg Madrasa in Samarkand, Uzbekistan), originating from the Silk Road area, was carried out due to the size of the facility, divided into several parts. The obtained replica of the minaret was presented to people with simulated pattern dysfunction and tested in a pilot test. The obtained results confirmed that the decomposition of the object for the purposes of 3D modelling, the diversified scaling of individual elements to make real 3D replicas of the digital model facilitated the kinesthetic recognition of the relevant architectural object for the respondents.

Opis:

This study examines the possibility of implementing intelligent artificial limbs for patients after injuries or amputations. Brain-computer technology allows signals to be acquired and sent between the brain and an external device. Upper limb prostheses, however, are quite a complicated tool, because the hand itself has a very complex structure and consists of several joints. The most complicated joint is undoubtedly the saddle joint, which is located at the base of the thumb. You need to demonstrate adequate anatomical knowledge to construct a prosthesis that will be easy to use and resemble a human hand as much as possible. It is also important to create the right control system with the right software that will easily work together with the brain-computer interface. Therefore, the proposed solution in this work consists of three parts, which are: the Emotiv EPOC + Neuroheadsets, a control system made of a servo and an Arduino UNO board (with dedicated software), and a hand prosthesis model made in the three-dimensional graphic program Blender and printed using a 3D printer. Such a hand prosthesis controlled by a signal from the brain could help people with disabilities after amputations and people who have damaged innervation at the stump site.

Opis:

New materials and filaments dedicated to 3D printing were obtained using the fused deposition modeling method, and the properties of the produced materials were investigated. Polylactide was used as a polymer base for the assays because of the desired properties of the polymer, mainly biodegradability, and the matrix was refilled by the addition of metallic nanofillers, such as bronze, copper, brass, and steel. For the composites obtained, mechanical properties were investigated to determine the dependence of the obtained results on the content and type of filler used and on the method of fabrication of the fittings. It was found that the additives present in the polymer matrix increased the fluidity of the material. The best results were obtained for the compositions with bronze and steel in which the mass flow rate was 72.97 and 79.99 g/10 min, respectively. The filled material that had lower hardness was measured by Rockwell and the impact strength was measured by Charpy. In addition, it was found that injection-molded parts obtained much better mechanical properties than those obtained by 3D printing.

Opis:

The paper provides an overview on the materials used in the 3D printing technology (the Polish and foreign market) with a particular focus on flexible filaments and their possible application in the industry. There are described the techniques of 3D printing and modern filaments available on the market. There is observed the increase of interest in the production of products from filaments based on thermoplastic elastomers (TPE), including the applications in the electronics and medicine, especially in tissue engineering. Ability to modify the physical and mechanical properties of thermoplastic elastomers, combined with their unique elastic and processability properties, opens new possibilities for engineers, designers and bio-engineers. The possibility to use new materials in 3D printing can contribute to faster development of research and accelerates implementation of innovative products.
Praca stanowi przegląd dostępnych na rynku krajowym i zagranicznym materiałów używanych w technologii druku 3D. Szczególną uwagę poświęcono elastycznym włóknom (ang. flexible filaments) oraz ich potencjalnemu zastosowaniu w przemyśle. Przedstawiono i oceniono stosowane technologie druku 3D. Scharakteryzowano nowoczesne włókna kompozytowe, ich właściwości i zastosowanie. Opisano także najnowsze doniesienia literaturowe związane z otrzymywaniem nowoczesnych termoplastycznych elastomerów (TPE) do wykorzystania w technologii druku 3D. Na podstawie przeanalizowanych publikacji zauważono ogromny wzrost zainteresowania wykorzystaniem termoplastycznych poliuretanów (TPU) w przemyśle elektronicznym, medycznym oraz obuwniczym. Dostępne na rynku nowoczesne produkty wykonane przy użyciu drukarek 3D z wykorzystaniem TPU, potwierdzają te doniesienia. Interesujące jest wykorzystanie wodnych dyspersji TPU z możliwą kontrolą bioaktywności do zastosowań w inżynierii tkankowej. Dodatek do wodnych dyspersji TPU, biopolimerów lub poli(tlenku etylenu) (PEO) powoduje znaczny wzrost ich lepkości. Pozwala to na użycie tego materiału w drukarkach 3D w technologii niskotemperaturowego drukowania (LFDM). Możliwość kontrolowanej zmiany właściwości fizycznych i mechanicznych, wyjątkowa elastyczność, trwałość oraz łatwość przetwórstwa termoplastycznych elastomerów otwierają nowe możliwości wykorzystania druku 3D. Dzięki temu technologia ta przestaje być narzędziem jedynie do prototypowania – umożliwia ona drukowanie materiałów gotowych do użytku na skalę przemysłową.

Opis:

Technological advancement, availability and common use of diagnostic imaging slowly but consistently leads to a change in its nature from being additional studies to becoming the basis for diagnostic process and treatment planning especially in complex cases that require surgical treatment. CT angiography study presentation using the illusion called “Pepper’s Ghost” in comparison to a three-dimensional printout and regular CT scan has been made to point out the relevance of research and implementation of new technologies in the diagnosis and surgical planning. Our image, despite being far from ideal and being just an illusion of a hologram, was more appealing and detailed to surgeons in comparison to a printed 3D model and standard CT angiography displayed with Osirix software. In order to change the existing methods of presenting imaging studies, it is advisable to use latest technologies, and among those currently available, ones based on virtual or mixed reality deserve special attention.

Opis:

Purpose: This article focuses on a comparative analysis of the technology of additive shaping and multi-axis CNC machining. The authors examine the impact of 3D printing assumptions and CNC machining conditions on the strength of the selected PET material used to produce machine elements on the example of a shaft-type element. The purpose of the study is to identify a better production method. Design/methodology/approach: The analysis was carried out by producing six samples of different diameters and lengths from the same thermoplastic material (ethylene terephthalate) by both 3D printing (FDM) and CNC machining. The resulting samples were subjected to a static compression test, for which a universal testing machine by Zwick & Roell 100 kN was used. The following factors during the production of elements were compared: the difficulty of preparing the project, the time of execution, the cost of execution, the accuracy of the execution and the properties of the elements made. Findings: Elements made by CNC machining have higher compressive strength and yield strength, as well as lower relative expansion and relative shortening. Those produced by CNC machining are created as a monolith (semi-finished product), and the printed elements are incrementally shaped layer by layer. During the strength test, the spaces between the layers decrease, which in turn causes an increase in relative shortening and a decrease in strength properties. Research limitations/implications: Further research is planned on the analysis of manufacturing technology using incremental shaping technology (e.g. change of filling density, change of filling type, change of material) compared to CNC machining. Practical implications: In the conducted tests, a universal method was used, which can be translated into a comparative study of elements made of other materials. Originality/value: The research carried out allowed for the initial assessment of the use of PET material for the production of machine elements through 3D printing and CNC machining.
