【摘要】：三维打印中填充路径的好坏直接影响制件的质量,针对人工牙槽骨选择较优的填充路径尤为重要。将具有良好生物相容性、可降解性的羟基磷灰石和海藻酸钠作为成型材料,选择不同的填充路径,通过自行开发的三维打印成型设备,采用气动挤出沉积成型工艺,制造出同种规格的牙槽骨。获得了不同路径下牙槽骨的宏观表征、微观结构及力学性能参数,并对其影响因素做了分析和探讨。为后期人工牙槽骨填充路径的选择和优化可提供一定的参考。
[Abstract]:The quality of the filling path in 3D printing directly affects the quality of the parts. It is particularly important to select a better filling path for the artificial alveolar bone. Taking hydroxyapatite and sodium alginate, which have good biocompatibility and biodegradability, as molding materials, choosing different filling paths, adopting pneumatic extrusion deposition molding process through a three dimensional printing molding equipment developed by ourselves. Create alveolar bone of the same size. The macroscopical characterization, microstructure and mechanical properties of alveolar bone under different paths were obtained, and the influencing factors were analyzed and discussed. It can provide some reference for the selection and optimization of artificial alveolar bone filling path.
