Extrusion-Based 3D Printing of Biodegradable, Osteogenic, Paramagnetic, and Porous FeMn-Akermanite Bone Substitutes

The authors developed inks containing Fe, 35 wt% Mn, and 20 or 30 vol% akermanite powder mixtures. 3D printing was optimized together with the debinding and sintering steps to obtain scaffolds with interconnected porosity of 69%.
