高强度可降解的3D打印材料及其制备方法
摘要：
本发明提供了一种高强度可降解的3D打印材料及其制备方法，该高强度可降解的3D打印材料及其制备方法包括：包括：100份的聚羟基脂肪酸酯/羟基磷灰石的复合物和0.2~2份的白蜡油；其中，所述聚羟基脂肪酸酯/羟基磷灰石的复合物包含聚羟基脂肪酸酯及羟基磷灰石，其质量比为8:2。本发明的有益效果是：本发明所获得聚羟基脂肪酸酯复合羟基磷灰石，具有可完全降解的同时，无酸性代谢产物的产生，有效避免目前临床上内固定材料所产生的无菌性炎症反应并发症的发生，同时，羟基磷灰石可有效提高内固定材料的机械强度，扩大目前临床上内固定材料的使用范围。
摘要（英）：

The invention provides a high-strength degradable 3D printing material and a preparation method thereof. The high-strength degradable 3D printing material comprises 100 parts of a polyhydroxyalkanoate/hydroxyapatite compound and 0.2-2 parts of white wax oil, wherein the polyhydroxyalkanoate/hydroxyapatite compound comprises polyhydroxyalkanoate and hydroxyapatite with the mass ratio to be 8 to 2. The high-strength degradable 3D printing material has the benefits that the obtained polyhydroxyalkanoate/hydroxyapatite compound is completely degradable, cannot generate acidic metabolites and effectively avoids occurrence of aseptic inflammation complications caused by internal fixation materials clinically at present. At the same time, the hydroxyapatite can effectively improve the mechanical strength of the internal fixation materials and expands the range of application of the internal fixation materials used clinically at present.
