BIOMATERIALS PROCESSING BY RP TECHNOLOGIES (RAPID PROTOTYPING) USED IN THE IMPLANTS MANUFACTURING

Biomaterials used to selective laser sintering process are made by powders of stainless steel, titanium powders and composite powders titan-hydroxyapathite. The titan alloy TA6V is used frequently in ortopaedic prothesis because presents a good resistance to corrosion due to the titanium oxide layer on the surface of the metal who prevents the achievement of reactions between titanium and surrounding environment and it's not toxic for human body. The hydroxyapathite contains collagen like the structure of bone and can be more easy to integrate the implantsto human body.
