| Abstract Scope |
Binder jet powder-based 3D printing is a multistep additive manufacturing technology compatible with various metals and ceramics. The absence of high temperature during the printing process can reduce the probable thermal distortion and defects such as residual stress and cracking. However, the lack of an in-depth understanding of physical properties such as geometry and mechanical characteristics limits its wider adoption. This study aims to investigate the binder jetting 3D printing of 17-4 PH stainless steel parts with the comprehensive characterization of part dimensional and mechanical properties. The cuboid and dog bone-shaped samples were printed in four different lengths to assess the effect of size on part densification and distortions. The anisotropic shrinkage was examined for different sizes and buildup directions, and its influence on the part sintering. Additionally, by using metallurgical optical and electron microscopy, the correlation between microstructures, geometrical precision and mechanical properties were investigated. |
