摘要：Nowadays, it is very desirable to obtain the low cost polymeric material with the best material properties. For the best modification of the commodity and construction polymeric materials it is firstly necessary to know the basic material properties. In this study the bending and Charpy impact test specimens were fabricated via a professional FDM 3D printer Fortus 900mc, from company Stratasys, processing ABS-M30 in three build orientation XY, XZ-H and XZ-V. The 3D printed test specimens were examined to compare the effect of layer thickness and building orientation. Tensile test machine Zwick 1456 and impact pendulum Zwick HIT50P were used for bending and Charpy impact tests. Optical microscopy was utilized to perform fractography on impact test specimens to explore the effect of the layer thickness and building orientation on the fracture surface morphology of the failed specimens. This study demonstrates the need for material testing for specific processing as additive manufacturing technologies.
