Abstract
The purpose of this research was to study tensile properties of 3D printing ABS material with axial and lateral direction. The specimen was printed according to ASTM D 632-02 by layer thickess variations around 0.1 mm, 0.2 mm and 0.3 mm. Moreover, three specimens was made for each printing direction. Tensile test was performed using Zwick Roell Series Z 021 machine. Then, the fracture surface was studied with scanning electron microscope (SEM). Based on the research from 6 variations layer of 3D printing, the optimal result was found on the axial direction of 0,3 mm thickness layer with tensile strength 30,6 MPa and ultimate tensile strength 550,81 N. The voids were seen at the fracture surface.
