【摘要】：羟基磷灰石(Hydroxyapatite,HAP)是广泛应用于临床骨缺损修复的支架材料,但传统方法不易使其成型形状复杂的个人定制化人工骨植入物,因此,有必要将3D打印技术应用于HAP陶瓷成型。以HAP粉末和光敏树脂为原料,通过粘度测试,制备HAP质量比为30%的混合物,用于光固化面曝光3D打印技术成型陶瓷坯体。根据热重(Thermogravimetric,TG)和差热(Differential Scanning Calorimetry,DSC)分析结果,发现光敏树脂分解的主要温度区间为300℃至500℃,由此确定坯体的烧结工艺参数,包括烧结的温度范围和升温速度,烧制得到的成型件,体积收缩约为65.2%,通过X射线衍射(X-ray diffraction,XRD)分析其物相组成。实验结果证明,利用光固化面曝光3D打印技术能够成型陶瓷坯体,通过适当的高温处理,可去除原料中的光敏树脂,得到陶瓷制件。
[Abstract]:Hydroxyapatite hydroxyapatite (HAP) is a widely used scaffold material for clinical bone defect repair. However, the traditional method is not easy to make it shape complex personal customized artificial bone implants. Therefore, it is necessary to apply 3D printing technology to HAP ceramic molding. HAP powder and Guang Min resin are used as raw materials. A mixture of HAP mass ratio of 30% was prepared by viscosity test, which was used to form ceramic billets by photo-curing surface exposure 3D printing technology. Thermogravimetric was used according to thermogravimetric thermogravimetric. TG) and differential Scanning calorimetry (DSC). It is found that the main temperature range of Guang Min resin decomposition is from 300 鈩，
