The aim of the study was to understand the influence of the technological parameters of 3D printing in FDM (Fused Deposition Modeling) technology on the mechanical properties of MABS and PET material. Samples for static tensile tests were printed in accordance with PN-EN ISO 527: 1998. Plastics. Determination of mechanical properties under static stretching. The print parameters for each sample, regardless of the type of filament used, were the same. Only the filling parameter was modified by changing the density (20, 40, 80%) and the filling pattern (line pattern and honeycomb). Laboratory tests were carried out with the use of a universal testing machine. PET showed higher tensile strength values than MABS at different sample filling densities.
