Although the widespread use of titanium alloys is constrained by high costs, powder metallurgy techniques such as additive manufacturing (AM) represent an economical approach to fabricating titanium components. Various approaches to AM, along with examples of components made by different AM processes, are presented. The microstructures and mechanical properties of Ti-6Al-4V produced by AM are also discussed and compared with cast and wrought products. Finally, the economic advantages of AM compared to conventional processing are presented.
