摘要
快速成形系统中普遍使用STL文件作为数据输入格式。本文通过分析STL文件存在的各种微小特征,如尖角、凹角、扁平面等,以及台阶效应对零件成形精度造成的影响,提出了一种可获得最佳分层厚度和可正负误差补偿的切片算法,该算法比较适合用于变层厚的快速成形工艺。
STL file is widely used as the data input in rapid prototyping system. This paper analyzes all kinds of slight features that exit in the STL file, such as peaks, valleys, flat areas, and staircase effect which will influence the accuracy of the workpiece. An integrated slicing algorithm is proposed in this paper, which will obtain the optimal slicing thickness and repair the positive or negative tolerance. This algorithm is adaptively to be used in the rapid prototyping technology with changeable slicing thickness.
