摘要
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。
Modeling of calcium phosphate based on an LCD 3D printer using brushite and calcium hydroxide
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.
