Abstract

Selective Laser Melting (SLM), an additive manufacturing technology, shows a high potential for preparation of biomedical implants, especially from reason of its capability to achieve geometrically complex shapes. Therefore, a preliminary research was done in order to characterize microstructure and mechanical properties of titanium alloy Ti-6Al-4V, one of the most frequently used materials for orthopaedic implants. As results show, SLM yields comparable strength properties as the wrought material, thus makes it an appropriate manufacturing alternative. Only drawback is represented by reduced elongation associated with defect porosity, which can be, however, optimized by an ideal combination of process parameters. In conclusion, SLM has a good outlook for the preparation of customized medical devices exactly reproducing the patient’s defect being treated and porous implants with properties corresponding to human bone enhancing biological and mechanical fixation.
