3D printing known as additive manufacturing has been widely used in academics and industries to make various 3D objects for various applications. The strength of the 3D printing parts is different from its original material strength due to this additive manufacturing technique. The 3D printing parts should be treated as anisotropic materials. However, the information of mechanical property such as the ultimate strength of 3D printing parts is very limited. There is little information about the mechanical property of 3D printing parts at different print angles. This research was focused on exploring the mechanical properties of 3D printing objects. The tensile test specimen of two different materials: acrylonitrile butadiene styrene-electrostatic dissipative (ABS-ESD) and Nylon 12 were printed at the 5 different print angles through the Fortus 450mc 3D printer. Tensile test results, data analysis, detailed discussion and the empirical formula of the tensile strength of 3D printing objects vs different print angles will be presented.
