Polyethylene glycol diacrylate/biological ceramic paste and forming and printing method
The invention discloses a polyethylene glycol diacrylate/biological ceramic paste and a forming and printing method, and polyethylene glycol diacrylate (PEGDA) with biocompatibility replaces conventional acrylic resin and is mixed with biological ceramic to prepare the paste. Through the design of curing parameters, the polyethylene glycol diacrylate/biological ceramic paste is subjected to SLA curing forming. Degreasing and sintering treatment is not needed after forming, the original morphology of the biological ceramic can be reserved, the maximum biological activity of the biological ceramic can be exerted, and a cured and formed test piece can be directly applied to medical application. Besides, a complex porous structure can be prepared through the polyethylene glycol diacrylate/biological ceramic paste forming process, polyethylene glycol diacrylate is easily dissolved in water, residual paste in the porous structure can be removed through ultrasonic cleaning in water, and the problem that residual paste in a complex porous part prepared through conventional SLA is difficult to remove is solved.
本发明公开了一种聚乙二醇二丙烯酸酯/生物陶瓷膏料及成形打印方法，发明将具有生物相容性的聚乙二醇二丙烯酸酯(PEGDA)替代常规的丙烯酸树脂，与生物陶瓷混合制成膏料。通过固化参数的设计，聚乙二醇二丙烯酸酯/生物陶瓷膏料经SLA固化成形。成型后无需脱脂烧结处理，可以保留生物陶瓷的原始形貌，发挥其最大的生物活性，固化成形的试件可以直接进行医学应用。另外，本发明提出的聚乙二醇二丙烯酸酯/生物陶瓷膏料成形工艺，可以制备复杂多孔结构，聚乙二醇二丙烯酸酯易溶于水，水中超声清洗即可去除多孔结构内部的残余膏料，解决常规SLA制备复杂多孔件内部残余膏料清除困难的问题。
