%X Biomaterial powders are in high development due to
expansion of additive manufacturing (AM) processes. Selective laser melting
(SLM) is a particular AM technology, which completely melts a powder bed layer
by laser beam. Investigations of appropriated physical properties of feedstock
(powder alloy) were the aim of this study. Cobalt-chromium-molybdenum
(Co-Cr-Mo) alloy was used to overview of gas-atomized powder properties in
different granulometric ranges (D1 12 - 19 ¦Ìm, D2 20 - 46 ¦Ìm and D3 76 - 106
¦Ìm), as their: physical, chemical properties and thermal analysis. SLM
manufactured standard tensile specimens of usually granulometric range powder
size provided mechanical, chemical and thermal properties of biocompatible
Co-Cr-Mo alloy. The physical properties showed that powders in the range of 20
to 50 ¦Ìm provide a better flow ability and packed density, which are relevant characteristics
to SLM processing. Manufacturing by SLM process provided suitable mechanical
properties in the health area, as well as, maintained the biocompatible
properties of the Co-Cr-Mo alloy.
