Sažetak
The main objective of research was to determine the impact of sample’s structure and building orientation on the tensile strength of 3D printed samples and thus to determine the combination that provides the highest strength. Test samples were prepared on a Z Corporation’s 3D printer model Z310, with variations of internal geometrical structure, variations of longitudinal orientation and also variations of base alignment. Results of tensile test revealed that the honeycomb structured samples built by orienting along axis Y and aligned over their thinner bases inside the printer building box exhibit the highest strength. Moreover, analysis of variance revealed that only individual main factors (structure, orientation and base) and the interaction of all three of them are significant, as well. All experiment combinations revealed applicable strength when compared to full-bodied samples
