Abstract
Porous metallic components are known for their multifunctions in a variety of industries. However, the fabrication of porous metal parts via the conventional manufacturing processes, such as metal injection molding and metal sintering, is largely constrained due to their dependency on templates or supports. Additive manufacturing techniques have no such limitations. Binder jetting is a powder-bed-based additive manufacturing technique, and it has the inherent advantages in fabricating high porous components through the pores-by-process approach. In this work, the manufacturing process of porous CoCrFeMnNi high entropy alloy using binder jetting was investigated. Part porosities in the range of 35 %
