Abstract

Selective laser melting (SLM) allows the direct fabrication of metal functional parts with complex shapes from digital models. In particular, metallic scaffolds with lattice structures and controlled porosity for orthopedic applications have recently gained interest, exploiting SLM manufacturing technique. In this review, the current developments in SLM for metallic scaffolds fabrication has been highlighted. The paper focuses on the manufacturability of metallic scaffolds by SLM and their mechanical properties. This paper will serve as a guidance for implementing SLM for manufacturing medical devices.
