摘　　要：利用clipper库(二维图形裁剪库)对3D打印过程中生成的上下两层切片轮廓进行布尔运算,得到当前层的支撑区域,使用逆向分层的思想得到模型的全部支撑区域,并采用直线扫描的方式对支撑区域添加薄板支撑。通过桌面3D打印机打印实验证明,该算法简化了运算,确保了支撑添加无遗漏。Using clipper library（ 2D graphics cutting library） to go on boolean operation for up and down two floors slice contour generated in the process of 3D printing to get the current layer support area and using reverse layered ideas to get all the support area of a model,together with the method of linear scanning for the support area to add support plate,. And it has been carried on the experiment on the desktop 3D printer. The experiments show that the algorithm simplifies the operation,and ensures the support without omission.
