本文利用翘曲变形模型研究了激光快速成型工件翘曲变形；对材料固化收缩与翘曲变形的定量关系进行了分析；对翘曲变形受树脂光聚合速率以及活性稀释剂结构影响的实验结果进行了理论探讨；提出了为减少翘曲变形在成型材料方面的改进措施。 In this paper, the warp deformation model was used to study the warpage deformation of the laser rapid prototyping workpiece. The quantitative relationship between the cure shrinkage and the warp deformation was analyzed. The experimental results of the warp deformation affected by the photopolymerization rate of the resin and the structure of the reactive diluent The theoretical discussion was put forward; the improvement measures in reducing the warp deformation in the molding material were put forward.
