20.500.12556/RUL-141208 Mehanske lastnosti 3D natisnjenih elementov diplomska naloga št.: 434/B-GR Mechanical properties of 3D printed elements graduation thesis no.: 434/B-GR 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. 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. gradbeništvo diplomske naloge UNI GR B-GR 3D tisk preizkušanje 3D natisnjenih vzorcev natezni preizkus mehanske lastnosti graduation thesis civil engineering 3D printing testing of 3D printed elements tensile testing mechanical properties true false false [K.
