Abstract
Zaključna naloga zajema načine gradnje izdelkov z DLP (direct light processing) 3D-tiskalnikom, pri katerem izdelki nastanejo kot posledica direktnega projiciranja svetlobe na tekoč fotopolimer. Prav tako obravnava posodobitve v DLP-stereolitografiji, ki so omogočile hitrejšo in enostavnejšo izgradnjo izdelkov v omenjenem načinu 3D-tiskanja. V grobem je obravnavan vpliv kisika na proces fotopolimerizacije, na katerem temelji DLP-stereolitografija. Naloga prav tako predstavi vpliv kisika na debelino strnjenega sloja in posebej na moč vezave med dvema strnjenima slojema. Obravnavan je postopek kontinuiranega tiskanja CLIP (continuous liquid interface production), katerega ključ je t. i. mrtva cona, ki prepreči proces fotopolimerizacije zaradi prisotnosti kisika.

Title:Principles of building product by DLP stereolitography
Abstract:
The thesis encompasses the ways of building products with DLP (direct light processing) 3D printer, in which the products are made as an effect of direct light projecting on a liquid fotopolymer. It also deals with the updates in DLP stereolithography, which enabled faster and more simple development of products in this kind of 3d printing. The thesis also treats briefly with the impact of the oxygen that it has on the process of photopolymerization, on which the whole DLP stereolithography is based on. The assignment presents the impact of the oxygen on the thickness of tightened layer and especially on the strength between the two layer that are tightened together. The thesis deals with the continuous method of printing CLIP (continuous liquid interface production), where the key is the so-called dead zone, which prevents the process of photopolymerization due to the presence of the oxygen.

Keywords:stereolithography, DLP, 3D-printing, oxygen, CLIP, passive knife, active knife, additive technologies, photopolymer
