This work shows the route to develop additively manufactured bioabsorbable composite materials for orthopaedic applications by combining Poly(L-D- Lactide) (PLDL) and Mg/Zn particles (~40µm) of various volume fractions into 3D printable filaments to overcome the individual disadvantages associated with the bioabsorbable polymers and metals. Porous bioabsorbable bone scaffolds of various structural organisation (e.g. FCC, BCC) were developed and their mechanical, degradation, and cytocompatibility properties were determined. Degradation was evaluated through the mechanical tests of scaffolds that were immersed in simulated body fluids for various periods of time (up to 60 days) while cytocompatibility tests were carried out in line with ISO 10993-1 recommendations for both direct and indirect assays.
