3D PRINTED PATTERNS FOR METAL CASTING

U radu je opisano korištenje aditivnih tehnologija za izradu modela, prvenstveno izrada modela za kalupe pomoću 3D ispisa. Uz općenit opis samih modela za kalupe, obrađeni su pojedinačni aditivni postupci poput stereolitografije, PolyJet, taložnog očvršćivanja te selektivnog lasersko srašćivanje. Na kraju rada opisani su voštani modeli te postupak njihovog dobivanja kao i njihova primjena.In the paper, use of additive techonologies is explained as a purpose for making models, primarly for making models for molds using 3D printing. With the general description of models for molds, there is an individual explanation for some additive techonologies such as stereolithography, PolyJet, Fused Deposition Modeling and Selective Laser Sintering. At the end of the paper, wax models are explained and the way of making them aswell as their application
