Direct Metal Laser Sintering (DMLS) is an advanced manufacturing technology based on layer-by-layer deposition for the production of complex functional mechanical parts. In the DMLS technology, a solid-state laser controlled by a scanning system sinters successive layers of a metal powder in accordance to the previously realized CAD/CAM model. In the biomedical field, DMLS is a promising technology for prosthetic applications where complex geometries, low volumes and strong individualization are required. Co- and Ti-based alloys are extensively used in biomedical applications due to their mechanical properties and biocompatibiliy. In this study, a Co-Cr-Mo composition suitable for biomedical applications and a Ti-6Al-4V alloy were produced by the DMLS technology. In order to study the structure stability of the alloys, samples were submitted to thermal treatments.
