| Abstract Scope |
Biodegradable magnesium (Mg) scaffolds have garnered increasing attention for potential use as temporary implants in orthopedic applications due to their favorable mechanical, electrochemical, and biological properties. Nevertheless, Mg scaffolds continue to present certain challenges, including as high degradation rate, low mechanical properties, and difficult fabrication methods. Although additive manufacturing (AM) offers unique opportunities for fabricating porous Mg scaffolds, current attempts to apply the AM approach to Mg scaffolds have encountered significant challenges, particularly in terms of safety and composition control. This study presents Mg-Zn-Mn-Sr scaffolds fabricated by material extrusion-based AM for biodegradable implants. The fabrication process comprises three steps: (i) preparation of a Mg powder-loaded ink with the desired rheological properties, (ii) 3D printing of the ink to form scaffolds, and (iii) debinding and sintering to remove the binder in the ink and then bond Mg powder particles by applying a liquid-phase sintering approach. |
