Abstract: Selective Laser Sintering, SLS, is a rapid prototyping technique, based on additive manufacturing. It enables fast, flexible, and efficient manufacturing of complex parts, customized according to the requirements of users. Research results on SLS additive manufacturing technique and its specific materials, like Ti alloy powders (Ti-6Al-4V) for hip implants are presented in this paper. The research is on various parameters values for the SLS process (laser power, focal diameter of the laser beam, number and direction of laser beam passes) and their influence on mechanical characteristics (strength resistance and fracture surface) of the sintered samples. Some metallographic tests and the electron microscopy evidence the influence of laser spot direction on the sintering process of Ti alloy powders. The scope of this paper is to study the various mechanical and morphological characteristics of Ti-6Al-4V selective laser sintered material used for hip implant. There is the need for this research to avoid accidentally break of implants and mixing the powders with human tissues.
