摘　　要：针对快速成型中对工件模型添加支撑结构的需求,提出了一种基于FDM型3D打印机工件快速成型算法,实现了对待支撑面、悬吊线和悬吊点几何特征的提取。对各类区域的形状特点采用不同的填充算法进行支撑结构填充,使用三点法确定支撑的生长初始点和终止点。最终用对设计的自动添加支撑算法进行验证,结果表明该算法能够减少打印材料使用量,节省加工时的数据预处理时间,提高快速成形的效率。Aiming at the requirement of adding support structure to workpiece model in rapid prototyping,a rapid prototyping algorithm based on FDM 3D printer is proposed,which achieves the extraction of geometric features of support surface,suspension line and suspension point.The support structure is filled with different filling algorithms,and the three point method is used to determine the initial growth point and the end point of the support.Finally,the support algorithm is applied to verify the results of the design.
