Advances in processes using the powder metallurgy techniques are making this technology competitive compared to the other traditional manufacturing processes, especially in medicine area. The additive manufacturing technique ??? selective laser melting (SLM) was applied in a biomaterial of CoCrMo alloy (ASTMF75), to study the mechanical properties and microstructural characterization in comparison between the conventional technique ??? lost wax casting. Yet there is an important knowledge of performance properties, dimensional, mechanical and microstructural of this sintered alloy compared to casting, as reported recently (MERGULH??O et al., 2015a, 2015b; PODEST?? et al., 2015). The aim of this study is to demonstrate the mechanical properties and microstructures of specimens manufactured by powder metallurgy techniques using the SLM, using the Co-Cr-Mo alloy in the form of particulate matter.
