Influence of position in 3D printing process on mechanical properties of metal prints

This paper researches the influence of the placement during the 3D printing process on the quality of the final product. The tensile tests were carried out on standard dog-bone specimens, which were printed both horizontally or vertically with three orientation angles 0°, 45°, 90° to the main direction of the plate. The main goal of the measurements was to determine the influence of the printing orientation and placement of the specimens on the mechanical properties. Obtained data were evaluated and used for the determination of the best printing orientation.
