Abstract

This study analyzes the mechanical and physical characteristics of a metal plate manufactured by 3D printing and machining. We performed static and dynamic three-point bending tests, measured the surface roughness and hardness, and determined the presence of internals defect through computed tomography. The results of static and dynamic three-point bending tests showed good and poor performance of the plate manufactured by 3D printing, respectively. In conclusion, although good results were obtained in terms of static hardness of the plate manufactured by 3D printing, a weaker result was obtained under the condition of repeated loading. Thus, it is considered that heat treatment is needed for the plate design to be compatible with 3D printing-manufacturing with sufficient endurance for repeated loading.
