| Abstract Scope |
Binder jet 3D-printing (BJ3DP) is a solid-state powder bed additive manufacturing process. Powder bed additive manufacturing in general has seen remarkable growth in recent years due to its ability to produce metal components with complex geometries and feature with minimal lead time and waste material. The aim of this research is to investigate the relation between process parameters in BJ3DP and the properties of coupons with the same geometry. Binder saturation was determined as the most important factor affecting green density out of five printing parameters, including oscillation speed, recoat speed, roller traverse speed, and roller rotation speed for water atomized Inconel 625 alloy through fractional factorial design of experiment. Detailed examination of the effect of binder saturation was performed on both irregular water atomized and spherical gas atomized powders. The green density, dimensional accuracy, sintered density, shrinkage and mechanical properties was investigated. |
