Abstract
Široko področje 3D-tiskanja zajema različne tehnologije katerih uporabnost se je izkazala na mnogih področjih. Zaključna naloga obravnava konkretno metodo ciljnega nalaganja (FDM). Predstavljen je potek izdelave preizkušancev iz poliamida 6 za Charpyjev udarni in tritočkovni upogibni preizkus s spreminjanjem parametrov oblike strukture in odstotka zapolnjenosti. Ugotovili smo, da se udarna žilavost preizkušancev z višanjem odstotka zapolnjenosti manjša, upogibna trdnost pa povečuje. Maksimalno silo in upogibno napetost prenesejo preizkušanci s 100 % zapolnjenostjo, medtem ko maksimalno udarno žilavost dosegajo preizkušanci z 0 % zapolnjenostjo.

Title:Influence of 3D FDM printing parameters on mechanical properties of polyamide parts
Abstract:
3D-printing covers a wide range of different technologies whose usefulness has proven in many areas. The final task deals with a fused deposition modelling (FDM) technology. Presented is the process of producing specimens of polyamide 6 for Charpy impact and three-point flexural test, where the parameters of the infill structure and the percentage of the infill is changing. We discovered that the impact strength of the test specimens falls with rising percentages of infill, while the flexural strength increases. The maximum force and flexural strength are achieved in specimens with a 100 % infill, while the maximum impact strength is achieved by the specimens with a 0 % infill.

Keywords:3D-printing, FDM, polyamide, infill rate, Charpy test, flexural test
