Improved mechanical properties of 3D printed calcium phosphate scaffolds for craniofacial reconstruction

摘要

Although powder printing yields porosity, biocompatibility, and precise defect contouring required for craniofacial reconstruction, brittle failure must be mitigated for clinical translation. Herein we report improved flexural strength with sintering with minimal alteration in porosity. Ongoing work includes polymeric composite deposition to optimize fracture toughness as well as microstructural characterization via scanning electron microscopy.
