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:

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:

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:

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 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:

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:

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.

Opis:

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.

Additive processes allow for almost any manufacturing of screw-threaded joint elements. 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.
