摘要
立体光造型是一种应用广泛的快速成型技术,光敏树脂是光固化快速成型中制造各类形状零件的重要光致凝固材料。通过实验优化了合成立体光造型用树脂聚合物工艺参数,并用DSC、TGA和FTIR等测试方法对材料进行了表征。结果表明:环氧树脂的增强使样品具有更高的热稳定性,同时讨论了光固化过程中收缩与工艺参数之间相互关系。
Stereolithgraphy nowadays is one of the most common rapid prototyping techniques. Photosensitive resins are main materials in the stereolithography process to obtain parts with specific shapes and applications. In this paper, the optimization of synthesis conditions for photosensitive resins had been studied. Photosensitive resins were characterized by the DSC, TGA, and FTIR. The results show that the sample had higher thermal stability properties, with the most pronounced improvements obtained for the reinforced epoxy acrylate specimens. The relation between post - cure shrinkage and the various process parameters used in the SL also have been investigated.
