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:
Dynamic development of 3D printing technology contributes to its wide applicability. FDM (Fused Deposition Method) is the most known and popular 3D printing method due to its availability and affordability. It is also usable in design of technical objects – to verify design concepts with use of 3D printed prototypes. The prototypes are produced at lower cost and shorter time comparing to other manufacturing methods and might be used for a number of purposes depending on designed object’s features they reflect. In the article, usability of 3D printing method FDM for designing of technical objects is verified based on sample functional prototypes. Methodology applied to develop these prototypes and their stand tests are covered. General conclusion is that 3D printed prototypes manufactured with FDM method proved to be useful for verifying new concepts within design processes carried out in KOMAG.

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].

Opis:
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.
