Abstract: The aim of this work is to analyze and optimize the 3D printing
process, focusing on the influence of printing parameters on the accuracy of
printed parts. Experiments were carried out with the Creality Ender 3 V2 Neo
printer, using various settings optimized by the RSM Design Expert software.
Two types of materials were used, PLA and PETG. The printed parts were
measured with a digital caliper and the deviations were calculated to determine
the best combinations of parameters. The size deviations of PLA parts were
smaller compared to PETG, printing nozzle size of 0.4 mm and a printing speed
of 30 mm/s produced the best results, fill degree of 90% was found to be optimal
for reducing deviations.
