Abstract

V diplomski nalogi sem raziskovala kako različni parametri pri 3D tisku vplivajo na končne mehanske lastnosti izmerjene v standardnem nateznem testu. Zanimalo me je, kako stopnja prekrivanja notranjih slojev vpliva na končne mehanske lastnosti, pri tem sem upoštevala 30 % in 70 % stopnjo prekrivanja. Primerjala sem pet različnih smeri tiska in temperature tiskanja 210, 230 in 250 °C. Raziskovala sem tudi razlike med materialoma PETG in PLA-CF. Za vsak parameter, ki me je zanimal, sem natisnila serijo z dvema vzorcema. Vsaka serija je bila izvedena v A in B verziji, kjer je A imela 30 % prekrivanje notranjih slojev in B 70 % prekrivanje. Material PLA-CF ima višji modul elastičnosti kot PETG, vendar ima PLA-CF nižjo nosilnost kot PETG. Rezultati so pokazali, da je vpliv nekaterih parametrov na nosilnost jasen, pri nekateri parametrih pa bi bilo potrebno izvesti več preiskav.

Secondary title: Mechanical properties of 3D printed elements
Secondary abstract: The goal of the thesis was to compare how different settings in 3D printing influence the mechanical properties obtained from a standard tensile test. The goal was to find out how the overlap of the inner layer affects the end result, whether a higher overlap results in better mechanical properties or not. Different directions of printing the inner layers and different printing temperatures were researched. Two materials, namely PETG and PLA-CF were considered. A series with two samples was printed for every parameter under consideration. Each series had two versions, where version A had a 30 % overlap of the inner layers and version B had a 70% overlap. The results show that the effect of some parameters on the ultimate strength is clear, while some of the parameters require further testing.
