Extrusion-based 3D printing of biodegradable porous iron for bone substitution

The treatment of large bone injuries continues to be challenging partially due to the limited quantity and quality of bone-replacing materials. Iron (Fe) and its alloys have been developed as a group of load-bearing biomaterials. Recent advances in additive manufacturing (AM) have enhanced the potential of Fe-based biomaterials as biodegradable...
