摘　　要：熔融沉积制造(FDM)是一种用填充方式来得到每层截面的快速成型工艺,由于成型轨迹的走向直接影响到成型件的外观和成型效率,因此选择一种好的成型算法格外重要。在目前现有的成型轨迹中,复合式扫描法由于在制件精度和加工效率上的诸多优势,成为研究的热点。基于分形填充和偏置填充本身所具有的优点,提出了一种复合优化轨迹的方法,并用分而治之算法对生成的路径进行了最大程度的优化,以减少喷头的开关次数和拉丝现象,保证制件的成型精度和强度,并且已成功应用在实际加工中。Fused deposition modeling （FDM）, a technique of rapid prototyping, is based on filling to process the cross-section of each part. Choosing a correct algorithm for filling path planning is very im- portant because the filling path directly influences the quality and processing efficiency of each part. Complex scanning, an algorithm recently used for path planning, attracts more and more scholars＇ at- tention due to its advantages. Based on the advantages of fractal and offset fillings, we present a com- plex filling optimization method. In order to reduce the switching frequency and stringing nozzles to ensure the accuracy and strength of molded parts, we use a divide and conquer algorithm to achieve optimal path generation, and it has been successfully used in actual processing.
