ABSTRACT
Magnesium alloys are attractive as potential biomedical implants due to their degradability, and excellent biological and mechanical compatibility. Several attempts are made to manufacture relatively degradable medical devices. In this chapter, the manufacturing process including casting, extrusion, drawing, powder metallurgy, laser cutting, etc. of various bioabsorbable Mg alloys implants (i.e., cardiovascular stents, screws, wires, and so on) are summarized; the affecting factors on the forming process (i.e., material, like composition, grain structure; parameters, like temperature, strain rate, lubrication, and so on) are discussed. The appropriate range of various parameters is propounded based on the optimization formability and service property. In particular, the concept of forming at low temperatures to prevent grain coarsening is suggested to obtain enhanced service performance. The development process of Mg degradable biomedical implants by additive manufacturing (3D printing) is also introduced. Lastly, the future trend in Mg-based implant manufacturing is proposed.
