Abstract
There is demand for the development of highly functional and flexible bone fillers to treat bone defects. This research aimed to fabricate calcium phosphate implants with a flexible porous design and sufficient compressive stress using a three-dimensional 3D printer. A mixed slurry of dicalcium phosphate, calcium hydroxide, photopolymerized resin, and polyethylene glycol (PEG) was prepared using a planetary ball mill. The slurry was formed into a porous model using a stereolithography-type 3D printer. Upon sintering, the resin and PEG evaporated and/or combusted, yielding a β- tricalcium phosphate (TCP) molding with porosity. This study proposes a novel method for freely molding calcium phosphate implants.
