Direct Fabrication of Metal Orthopedic Implants Using Electron Beam Melting Technology

Metal orthopedic implants have been used for many decades with great success. Replacement joints and plates for bone fractures are usually made from titanium, cobaltchromium or stainless steel. Through recent advancements in biomodeling, custom orthopedic implants can be designed. However, fabrication of these custom implants can be prohibitively expensive with traditional processes. With the introduction of Electron Beam Melting (EBM), direct fabrication of fully dense metal components is possible. In this paper, the development of titanium for the EBM-process will be discussed, and direct fabrication of custom designed orthopedic implants made out of steel and titanium will be demonstrated.
