Sažetak
In the paper, a tensile test was performed on in- house made tensile test machine. Test specimens are 3D printed and made according to the ISO 527-2 standard. The specimens are made of HI-PLA (High Impact Polylactide) polymer material with pronounced resistance to impact toughness which is closer, according to its characteristics, to ABS material properties. The test specimens were printed by FDM additive technology with different layer thickness and material infill percentage, and a central composite design (CCD) was conducted. The conducted experiment resulted in force-elongation diagrams for 11 states of the test specimens, on the basis of which the tensile strength of the HI-PLA material was calculated. The obtained values were compared with the tensile strength values for ABS material.
