Preparation and characterization of polyamide 12 composites for craniofacial reconstruction utilizing additive manufacturing

This study was carried out to prepare and characterize polyamide 12 composites as potential biomaterial for craniofacial reconstruction utilizing additive manufacturing. Polyamide 12 was compounded with ceramic fillers of β-TCP (ranged from 5 to 25 wt%) and zirconia (fixed at 15 wt%) via twin screw...
