Abstract

Tehnologija ciljnega nalaganja je ena najbolj razširjenih tehnologij v svetu 3D-tiskanja polimerov. Uporabljamo jo za 3D-tisk termoplastov, med drugim tudi za tisk izdelkov iz polivnil alkohola. Izkazalo se je, da imajo ti po izdelavi z uporabo procesnih parametrov, priporočenih s strani proizvajalca filamenta, zelo slabe trdnostne lastnosti, saj je pri majhnih obremenitvah prečno na plasti izdelka prišlo do delaminacije. V našem delu smo raziskovali vpliv izbire procesnih parametrov 3D-tiskanja za izboljšanje sprijetosti plasti izdelka. Osredotočili smo se na vpliv temperature okolice. To smo nadzorovali in spreminjali s pomočjo silikonskega grelca, ki smo ga vgradili pod glavo 3D-tiskalnika. Z nateznim preizkusom smo ugotovili, da povišana temperatura okolice pozitivno vpliva na sprijetost plasti izdelka.

Secondary title: Parameters of fused deposition modeling for improved polyvinyl alcohol product properties
Secondary abstract: Fused deposition modeling or Fused filament fabrication is one of the most commonly used technologies in the world of 3D printing. It is used to 3D print thermoplastics, including products made from polyvinyl alcohol polymer. These have been shown to have very poor strength properties after production using the process parameters recommended by the filament manufacturer, with delamination occurring at low loads across the product layers. In our work, we investigated the influence of the choice of 3D printing process parameters to improve the adhesion of the product layers. We focused on the influence of ambient temperature. This was controlled and varied using a silicone heater that was mounted under the 3D printer head. By tensile testing, we found that an increase in ambient temperature has a positive effect on the adhesion of the product layers.
