| Abstract Scope |
Additive manufacturing (AM) and biomedical devices appear as a natural match for enabling new functional devices with enhanced biological performance, customized to patient specifications. Concerning biodegradable metals, SLM allows for accurate control over the implant geometries and indirectly control over the mechanical properties and degradation behavior. This work focuses on SLM of biodegradable metals and alloys, such as Mg, Fe, Zn and Fe35Mn, and presents a comprehensive overview of the current research on this technology. In particular, SLM of pure Fe and Fe35Mn alloy for orthopedic applications is assessed. Initially, the processability of these materials for high density bulk components as well as thin struts is investigated. Material properties are characterized in terms of microstructure, strength and corrosion behavior. Then, porous bone scaffolds are manufactured and biological performance via in vitro and in vivo testing is presented. |
