Analysis of Dimensional Accuracy and Mechanical Properties of Plastic Components Made by 3D Printing
Horák, Ondřej ; Joska, Zdeněk (referee) ; Sedlák, Josef (advisor)
The Master's thesis deals with the determination of mechanical properties of materials used for 3D printing by ALPS ELECTRIC CZECH, s.r.o. (PETG, PLA, ABS, PLA ESD), extended of new materials (ASA, PC / ABS). The prepared test samples, produced by 3D printing technology Fused Deposition Modeling, were analyzed using mechanical tests (tensile test and two hardness tests), surface roughness and dimensional accuracy. Statistical evaluation was performed for individual materials of selected parameters (tensile strength, modulus of elasticity in tension, elongation, Shore hardness, hardness of ball indentation). The conclusion of the thesis is devoted to the comparison of materials by selected parameters and production costs. The additive material PLA Filament Plasty Mladeč proved to be the best with its properties and the second lowest price.
