Opis:
The article focuses on the subject of 3D printing. 3D printing technology and currently used solutions are described. The materials used in printing with the use of a filament printer and a resin printer are discussed. The fused deposiotion modeling technique and the LCD-based stereolithography. Printing technology were presented. Samples were prepared using 3D modeling software. The software used to make the models is discussed. The designed models were printed on two types of printers, using different model orientations. Printouts were measured several times. The obtained data was analyzed and the conclusions, proposed solutions and possible improvements to 3D printing were presented at the end. The article deals with the subject of the possibility of accelerating 3D prints due to their location, but also the influence of warming up the printer during subsequent prints was checked.

Opis:
Modified LCD-based method was used to print three-dimensional (3D) elements. This innovative method combines printing the external shell and filling, thus obtaining mould by casting resin. In order to compare the properties of prints obtained with this method with the ones fabricated in a standard procedure, we conducted bending tests of vertically/horizontally printed and shell-printed cast specimens. The shell-cast samples showed higher flexural strength and larger values of apparent Young’s modulus. The presented results also concern the kinetics of curing samples obtained with different fabrication routes.

Opis:
This paper shows the results of studying the technology of manufacturing cortical electrode-instruments (EI) with the use of indirect methods of the Rapid Prototyping technology. Functional EI prototypes were made by layered synthesis of the photopolymer material with the use of the stereolithography technology (SLA - Stereo Lithography Apparatus). The article is focused on two methods of indirect EI manufacturing. One of the EI prototypes was used for making a molded wax model for hot investment casting, followed by applying copper coating. The second prototype was used for applying copper plating to a prepared current-conductive layer. As a result of EDMing a steel workpiece, both EIs reached the desired depth, which is 1 mm. The copper plating applied to the EI preserves its integrity. Through the use of the casting technology, there is a possibility to cut the economic costs by 35%. Using a prototype with preliminarily applie conductive coating makes it possible to make geometrically-complex EIs.

Opis:
The presented research deals with the development of the numerical model for resins used for stereolithography (SLA) rapid prototyping. SLA is an additive method of production of models, prototypes, elements or parts of constructions with the use of 3D printing that covers photochemical processes by which light causes chemical monomers to link together to form polymers. Such method is very useful in design visualization, but also can be applied in numerical modelling for the purpose of validation and verifi-cation. In this application the resin strength parameters must be described and on the base of them the numerical material model is developed and validated. Such a study for SLA resins was presented in the paper.

Opis:
In this study we demonstrate an overview about possibilities in using additive manufacturing for tissue engineering and orthopedic prosthesis. We show the possibilities to produce scaffolds by using a low cost commercial stereolithography system under the use of biocompatible hydrogels like Poly(ethylene glycol) diacrylate. We also demonstrate that it is possible to use a low cost selective laser sintering system to produce individual prostheses to support the healing process in many orthopedic issues.

Opis:
The aim of this case study is to generate several poly(ethylene glycol) diacrylate-based hydrogels using additive manufacturing processes. The interest here is in determining different material properties. The test specimens are produced using a commercial stereolithography system. For this purpose, three formulations are prepared. The basis in each case is PEGDA with average molecular weights of 700 Mn, 575 Mn and 250 Mn. A photoinitiator and a UV absorber are added to ensure spatial and temporal cross-linking. Furthermore, the formulations are tested for their material properties according to ISO standards using tensile, compression and hardness tests. An equivalence can be found in the tensile and compression tests. The results with the molecular weights of 700 Mn and 575 Mn show values close to each other. However, the results of the material tests with the molecular weight of 250 Mn are ten times higher. The Shore A hardness values also correlate with the previous tests. These results between molecular weight and material property are particularly striking. A novel aspect of this method could be that the properties determined of these tailor-made high-performance polymers can be applied to different areas of application in an organism.

Opis:
The method of determining the accuracy of polymer molds in plaster forms has been discussed. Distortion of the surface of molds and plaster molds has been assessed. It has been found that the presence of monolithic and porous structure in the samples does not change the accuracy of the surfaces when forms are prepared for removing the material of the model. It has been found that in case of full-mold casting it is more expedient to form the mold cavity with cellular adjustable structures of molding prototypes.

Opis:
This paper investigates the effect of additive manufacturing parameters on the manufacturing quality of selected gear mechanism components. Three input variables, and two output variables were determined. The result was the determination of the most optimal combination of key parameters and the determination of regression equations. The concept of manufacturing objects of a very complex shape, by any person, under various conditions through the use of a low-cost device became the basis for this thesis topic. Curing time, layer thickness, and lift speed are among the basic parameters, with a large range of manipulation. A hypothesis was formulated that these three parameters are crucial to produce a part with the smallest possible deviations from the computer model. A handheld scanner was used to scan the samples and compare them with the CAD model. Based on the study, optimal parameters for layer thickness, curing time and lift speed were proposed.
