Analysis of the mechanical properties of plastic materials for 3D printing
Jelínek, Jan ; Bártková, Denisa (referee) ; Koutný, Daniel (advisor)
This work will solve the mechanical properties of materials used in the FDM technology.Thetensile and flexuralmechanical properties depending on theprintingparameterswillbetested. Fortestingare used three types of sampleswithdifferentrastersforeachof the tests. The first type of raster is characterized by a fundamentalparameter, whichisoffered by themanufacturer. The second type of raster is characterized by a high number of thin-fiber material and a higherconcentrationof air gaps. The third type of rasterischaracterized by minimalnumberof air gaps and a minimum number of thick-fibers in thecross-sectionalofsample. These typesofsamples will be tested on selected materials. The results of individual tests willbecomparedamongselectedmaterials and types of samples. The aim of this work is to show the dependence of mechanical properties on the type ofprintingstrategy.

Comparison of tensile properties of polymeric samples produced by extrusion based 3D printing
Krajcar, Ivo ; Vespalec, Arnošt (referee) ; Škaroupka, David (advisor)
The subject of this work is a summary of the contemporary knowledge about 3D printing and mechanical properties of a prototype manufactured this way. Main goal is to compare the frequently used FDM method with the innovative APF method of 3D printing from the Arburg company. ASA and CPE materials were chosen for researching this method. On these materials, tensile strength was measured. Aditionally, for comparison between the two methods, referential samples manufactured by injection moulding were made. A percentual difference in strength of each sample was compared against these. 60 samples in total were made for this comparison. After evaluation of the results, it was found that in the tensile strength the samples made by the APF method are approximately 30 % less strong than the referential sample. The samples made by the FDM method are approximately of the same strength as the referential sample.
