Development of Alloy Powders for Biomedical Additive Manufacturing

Abstract

Abstract Additive manufacturing (AM) techniques include powder-bed fusion (PBF), directed-energy deposition, binder jetting (BJ), extrusion-based desktop, vat photopolymerization, material jetting, and sheet lamination. The development of suitable powders for AM is a challenging task because of critical design parameters including chemical composition, flowability of powders, and melt surface tension. This article explains the fabrication methods of metal and novel alloy powders for medical applications. The development of zirconium alloy powder for laser-PBF is introduced as a case study.
