【摘要】：羥基磷灰石(Hydroxyapatite,HAP)是廣泛應(yīng)用于臨床骨缺損修復(fù)的支架材料,但傳統(tǒng)方法不易使其成型形狀復(fù)雜的個人定制化人工骨植入物,因此,有必要將3D打印技術(shù)應(yīng)用于HAP陶瓷成型。以HAP粉末和光敏樹脂為原料,通過粘度測試,制備HAP質(zhì)量比為30%的混合物,用于光固化面曝光3D打印技術(shù)成型陶瓷坯體。根據(jù)熱重(Thermogravimetric,TG)和差熱(Differential Scanning Calorimetry,DSC)分析結(jié)果,發(fā)現(xiàn)光敏樹脂分解的主要溫度區(qū)間為300℃至500℃,由此確定坯體的燒結(jié)工藝參數(shù),包括燒結(jié)的溫度范圍和升溫速度,燒制得到的成型件,體積收縮約為65.2%,通過X射線衍射(X-ray diffraction,XRD)分析其物相組成。實驗結(jié)果證明,利用光固化面曝光3D打印技術(shù)能夠成型陶瓷坯體,通過適當(dāng)?shù)母邷靥幚?可去除原料中的光敏樹脂,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，
