摘要 本研究对基于自由基聚合的3D打印材料二次固化后的变形情况进行表征。以脂肪族聚氨酯丙烯酸酯为主体,与单体和光引发剂混合配制成3D打印光固化树脂材料,用3D打印机打印模型,经过不同时间后用口内扫描仪扫描得到对应的数据,并用magic control x软件将其与刚刚二次固化后的模型数据对比得到能够表征变形情况的数据。结果表明,二次固化后的紫外光固化材料经过1 d、2 d、3 d后数据文件与刚固化后的数据文件不能完全重合,存在变形,且随紫外光光强的增加,变形明显减小。针对紫外光固化产品的二次固化后变形问题,本研究提供了一种表征方法,对在不同领域中开发固化速度快、性能优良、变形小的光敏树脂具有一定的指导意义。

Abstract: To characterize the deformation of 3D-printed materials after secondary curing based on free radical polymerization, aliphatic polyurethane acrylate was used as the main component, mixed with monomer and photoinitiator to prepare 3D printed and light-cured resin material. The model was printed by a 3D printer, the corresponding data were scanned by an intraoral scanner at different time points,which was compared with the data of model just cured twice to get the data for characterizing the deformation. After 1 d, 2 d, 3 d, the data of UV curing material model by secondary cured could not completely coincide with the data of the model just cured and the existence of deformation is proved, and with the increase of UV light intensity, the deformation decreases obviously. This study provides a method to characterize the deformation after secondary curing of UV cured products, it has guiding significance for the development of photosensitive resins with fast curing process, excellent properties and small deformation in different fields.
