光固化快速成形中复杂零件型面精度形成机理研究

Study on the Surface Finish of Complex Model Build in SLA

光固化（SL）快速原型面型精度（粗糙度、轮廓度等）一直难以提高，分析其形成机理及各种影响因素，给出提高精度的措施，并通过试验进行验证。

There are many factors which affect the surface finish of SLA part,and in thispaper, the main causes are analyzed in detail.Some procedures have been proposed not only toimprove the surface finish but also not to affectthe productivity. The experimental results confirmed that these procedures are effective.
