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.
人们需要开发高功能性和柔性骨填充物来治疗骨缺损。本研究旨在使用三维 3D 打印机制造具有柔性多孔设计和足够压应力的磷酸钙植入体。使用行星球磨机制备了磷酸二钙、氢氧化钙、光聚合树脂和聚乙二醇（PEG）的混合浆料。使用立体光刻式 3D 打印机将浆料制成多孔模型。烧结时，树脂和聚乙二醇蒸发和/或燃烧，产生了具有多孔性的β-磷酸三钙（TCP）模塑。本研究提出了一种自由成型磷酸钙植入物的新方法。
