Direct metal laser sintering or selective laser sintering is a rapid prototyping technique that consolidates, layer by layer, parts with complex shape from powders of a wide range of metallic materials. It has been used for fabrication of patient specific net-shaped parts of dense and porous titanium and its alloys for use as implants. But depending on the laser parameters, the powder can be fully melted during its consolidation. In this case, selective laser melting seems to be a more appropriate process denomination than selective laser sintering. In this work we use selective laser sintering/melting to consolidate Ti6Al4V porous parts from prealloyed powders in order to investigate the laser process parameters on the microstructure and mechanical properties of the parts. The consolidated samples were characterized by optical and scanning electron microscopy and compressive tests. The results showed a straight relationship between laser energy and mechanical properties.
