Abstract Scope Additive manufacturing (AM) has received widespread attention for generating 3D biodegradable scaffolds for tissue engineering comprising biodegradable metals. However, the highly reactive oxide layer present on the surface of the biodegradable magnesium pose many challenges resulting in 3D printed constructs with suboptimal mechanical and materials properties. This presentation addresses this issue using fused deposition modeling (FDM) printing of a novel bio-polymer and bio-metal containing composite material. The effect of printing temperature, layer height, and bio-polymer/bio-metal ratio on the mechanical properties, materials properties, and printed geometrical accuracy and reproducibility of the printed constructs was assessed. In-vitro cytocompatibility studies using MC3T3 pre-osteoblast as well as a pilot in-vivo rat calvarial defect model were also conducted. The presentation will present results from this study showcasing the importance and major influence of the various printing parameters on printing quality, reproducibility, and mechanical properties of the resultant 3D printed composite.
