Abstract

Tridimenzijsko (3D) tiskanje je vedno bolj priljubljeno tako kot orodje za hitro prototipiranje kot za tiskanje doma. Za tiskanje kakovostnih izdelkov je potrebno nastaviti ustrezne izdelovalne parametre. Izbrani materiali so bili akrilonitril butadien stiren (ABS), polilaurillaktam (PA12), polietilen tereftalat glikol (PETG), polilaktična kislina (PLA) in termoplastični poliuretan (TPU), saj spadajo med najpogostejše skupine polimernih materialov, ki se uporabljajo za 3D tisk. Zaključna naloga obsega proučevanje vpliva temperature na viskoznost izbranih polimernih materialov za 3D tisk. Viskoznost smo proučili z rotacijskim reometrom znotraj temperaturnega območja, ki ga predpisuje proizvajalec za določen material ter primerjali viskoznost vseh materialov pri isti temperaturi. Ugotovili smo, da temperatura različno vpliva na posamezen material, viskoznost posameznega materiala je bistveno drugačna. Prav tako se razlikuje viskoelastičen odziv.

Secondary title:	The influence of temperature and comparison of viscosity of materials for 3D printing
Secondary abstract:	Threedimensional (3D) printing is becoming increasingly popular as a tool for rapid prototyping as well as home printing. To print products of high quality, correct manufacturing parameters need to be set. Selected in the present study acrylonitrile butadiene styrene (ABS), polyurylactamate (PA12), polyethylene terephthalate glycol (PETG), polylactic acid (PLA) and thermoplastic polyurethane (TPU) were selected, as they belong to the most popular groups of polymeric 3D printing materials. In this study we studied the effect of temperature on the viscosity of selected materials. Viscosity was measured with a rotational rheometer within the temperature range specified by the manufacturer for a given material. Viscosities of all materials compared at a selected temperature. The results showed that the temperature has a different effect on each material, ergo the viscosity of each material is significantly different. The viscoelastic response also differed.
