Abstract
The selective laser sintering is a technique used to quickly fabricate a scale model of a physical part or assembly using three-dimensional computer aided design CAD data. This technique is used to obtain complex pieces in different domains like machine building industry, automotive industry, foundry and medicine. The selective laser sintering process is used to obtain different prototypes, medical instruments or personalized implants in medicine. The powders used to obtain the medical instruments and for implants must to be very resistant to corrosion, non-toxic and present good fatigue resistance. The powders used are in generally, stainless steel, alloy titan TA6V, alloy Co-Cr and different polyamides.
