Abstract

Na področju 3D-tiska obstaja veliko uporabnih tehnologij. V zaključni nalogi smo izbrali metodo ciljnega nalaganja (FDM). Predstavljen je postopek izbire parametrov tiskanja materiala PLA in ABS. Vse vzorce smo testirali na tritočkovnem upogibnem preizkuševališču. Ugotovili smo, da se upogibna napetost in sila s stopnjo zapolnitve preizkušancev zvišujeta. Največjo silo in upogibno napetost zdržijo preizkušanci iz PLA in s 100 % zapolnjenostjo. Preizkušance iz ABS, ki imajo 100 % zapolnjenost, bi lahko nadomestili s preizkušancem iz PLA in 30 % zapolnjenostjo, če bi bila notranja struktura trikotne oblike.

Secondary title: Bending strenght PLA and ABS parts manufactured by fused deposition modelling
Secondary abstract: In area of 3D-printing is a lot of usefull tehnologies. In this final task we used technology with fused deposition modelling. It presents the process of selecting the best parameters for printing PLA and ABS. All samples were tested in three-point bending test. We found that the bending tension and force increace with the filling level of test specimens. The maximum force and bending tension is sustained by PLA specimens which are filled 100 %. ABS specimens with 100 % infill could be replaced with PLA specimens which are filled only 30 %, if the internal structure were in a triangular shape.
