Laser additive manufacturing technology in titanium 64 implant of microstructure fabrication and analysis

Laser additive manufacturing technology is very attractive for industry applications due to the characterizations of rapid manufacture, flexible parameters select, customize, and complex 3D object fabricate. In this article, an EOS M-type direct metal laser sintering (DMLS) system was used to manufacture for customized hip implant with an IPG fiber laser. The part building process takes place inside an enclosed chamber filled with argon gas to minimize oxidation powdered material. We are successful design and producing an implant of imitation bone microstructure in titanium alloy. From the SEM analysis image, an approximately 100% dense surface has be observed. The mainly composition of selective laser additive manufacturing product are acicular structure of alpha-phase titanium. X-ray diffraction patterns also are observed the alpha-phase and beta-phase mixture. This customized hip implant is used to clinical application for replacement the golden retriever's femoral head, and it get good results. Imitation bone structure can promote the biocompatible of titanium material and bone.
