LAYER THICKNESS INFLUENCE OF MACRO- AND MICROSTRUCTURE QUALITY OF 3D PRINTED PARTS

In this paper will be analyzed the influence of the layer thickness on the micro and macro structure of the parts obtained by 3D printing, i.e. fused filament fabrication (FFF) technology. Specimens for analysis will be printed on the 3D printer Zotrax M 200, and the macro and microstructure will be done on the VHX 6000 microscope. It will be shown in the paper that by increasing the thickness of the layer, the time required for the production of the part will be significantly reduced, but also the quality of the surface is also significantly affected.
