Hočevar, Filip (author), Valentinčič, Joško (mentor), Lebar, Andrej (co-mentor)

V zaključni nalogi so na osnovi pregleda literature predstavljene informacije o stereolitografiji in fotopolimerizaciji. Na podlagi fotopolimerizacije s prostimi radikali in kationsko iniciirano fotopolimerizacijo je narejena primerjava med posameznimi fotopolimernimi smolami za stereolitografijo. Predstavljeni so tako načini inhibicije kisika kot tudi načini za zmanjšanje njegove inhibicije pri fotopolimerizaciji. Na podlagi dveh modelov za prikaz inhibicije kisika pri fotopolimerizaciji je narejena primerjava med vplivnimi parametri.

Abstract

In this thesis, information based on a literature review about stereolithography and polymerization is presented. Based on free radical and cationic photopolymerization the comparison between different photopolymer resins for stereolithography was made. In addition to oxygen inhibition pathways, strategies to reduce oxygen inhibition was presented. Then the thesis deals with comparison between variables of two models, which demonstrated the impact of oxygen inhibition during photopolymerization.
