针对基于面固化的快速成型技术应用于成型微小器件,设计了一整套的成型控制算法,包括CAD输出STL格式文件、VC环境下时其加载和显示算法,对STL模型的切片算法以及切片后截面轮廓的填充算法.分析了基于该控制算法,利用数字微反射镜器件(DMD)作为动态掩模板来实现面固化成型的制作方法的误差,并与传统的点固化成型法的制作误差进行了比较.结果表明,面固化成型法能够减小误差并提高成型速度,是一种有效的快速成型方法.

A control algorithm of rapid prototyping technology is designed for surface-curing used in forming small device.The control algorithm are made up of STL file outputted from CAD, loading and displaying STL file in VC, slicing algorithm based on the STL model and filling algorithm of the cross-section after slicing. Based on the control algorithm, the errors of the surface-curing molding method is analysed that was produced by using the Digital Micromirror Device (DMD) as a dynamic mask and compared with the traditional point-curing molding method's.The result shows that the surface-curing molding method can reduce errors and increase the speed of molding. It is a kind of effective method of rapid prototyping.
