摘　　要：对增材制造(3D打印)模型数据处理中分层线框轮廓的填充方式进行综述.针对不同的适用场景,将常用的3D打印工艺按照填充方式分为按路径连续填充和按需式阵列填充,对这两类填充方式进行了分析和对比.按路径连续填充的路径规划方法主要包括平行线填充路径、轮廓偏置填充路径和混合填充路径,按需式阵列填充的算法主要包括扫描线填充算法、边界标志填充算法、种子填充算法和扫描线种子填充算法.同时针对前沿的3D打印中的填充方法,结合具体实例阐述了多自由度的空间填充方法、多方法集成的填充方法和非均质零件的填充方法,并指出了3D打印填充方法的改进方向.This review aims to describe and discuss the fill method of hierarchical wireframe outline in additive manufacturing(3D printing).For different applicable scenarios,the commonly used 3D printing processes were divided into continuous filling by path and on-demand array filling according to the filling methods,and the two types of filling methods were discussed,analyzed and compared. The path planning method of continuous filling by path mainly includes parallel line filling path,contour offset filling path and mixed filling path. The algorithm of on-demand array filling mainly includes scan line filling algorithm,boundary mark filling algorithm,seed filling algorithm and scan line seed filling algorithm.At the same time,aiming at the filling methods in the cutting-edge 3D printing,the space filling methods of multi degree of freedom,the filling methods of multi method integration and the filling methods of heterogeneous parts with specific examples were expounded,and the improvement and development direction of the 3D printing filling methods was pointed out.
