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

This thesis presents a series of research publications leveraging the extrusion-based additive manufacturing (AM) technique to fabricate multi-functional porous iron (Fe) scaffolds for bone substitution.

We developed porous scaffolds composed of Fe, in situ alloyed with manganese (Mn), and reinforced with akermanite bioceramics.

The FeMn-akermanite scaffolds were paramagnetic and biodegradable in simulated body fluid, had mechanical properties similar to trabecular bone, and demonstrated osteogenic potential for bone tissue repair.
