Resumo
The aim of this study is the consolidation of Cobalt-Chromium (CoCr) alloy powder, using the additive rapid prototyping technique by selective laser sintering (SLS) and the conventional technique casting. The research of this study have been applied for this biomaterial to the development of prosthesis and dental implants. The gas atomized powder was analyzed by their physical and chemical properties. The mechanical properties as uniaxial tensile, three point bending and micro hardness were evaluated of standard samples manufactured by SLS and casting technique. The microstructural characterization were examined using optical microscope (OM) and SEM-EDS. The micrographs revealed a characteristic morphology of layer used in the SLS technique and the dendrites in the casting technique.
