摘　　要：详细研究快速成型的模型的切片方式,分析各个切片方法的优缺点,指出AutoCAD直接切片的可行性。在AutoCAD造型软件基础上进行了直接切片数据格式研究,利用AutoCAD宏开发了AutoSlice软件,可从任意复杂的CAD模型中快速直接地提取切片截面轮廓信息,采用BMP格式文件存储模型切片的轮廓信息,解决了构造模型的三维数据提取问题;基于LabVIEW IMAQ vision图象处理软件,开发了BMP数据读取程序,成功地解决了AutoCAD造型和电子束扫描控制系统之间数据传递问题。Slicing method of CAD model to be sintered for 3D scanning electron beam rapid prototyping is discussed in this paper. Different slicing methods are compared, and the direct slicing algorithm based on the second development of AutoCAD software is put forward.The slicing contour information saved in BMP fi^rmat files can be collected by the direct slicing algorithm from any complicated CAD models,and the BMP files is feasible to read by corresponding LabVIEW language program which can transfer slicing data from AutoCAD to Labview data file.
