摘　　要：为了研究熔融沉积成型(FDM) 3D打印技术的工艺路径规划(挤出路径、打印速度及挤出量等)对打印质量和打印效率的影响,提高FDM的打印效果,使用三款不同的工艺软件(QidiPrint,FlashPrint及Simplify3D)对工艺路径进行规划。通过分析三款不同的工艺软件的工艺路径规划算法和打印实体模型,发现三者的挤出方式虽然不同,但均采用复合挤出的方式,将偏置挤出和往复直线挤出的优点最大化,且由外向内的挤出方式打印模型表面质量更优;层间连贯轨迹的设计能增加打印的连贯性,可使产品具有更好的整体性;通过合理地安排挤出路径,有助于提高产品的表面工艺质量,减少打印过程中的走空路径,降低"台阶效应"和拉丝现象,节省打印时间和耗材用量。In order to study the influences of process path planning(extrusion path,printing speed and extrusion amount,etc.)of fused deposition moldeling(FDM)3D printing technology on printing quality and printing efficiency,and improve the printing effect of FDM,three different process software(QidiPrint,FlashPrint and Simplify3D)were used to plan the process path.By analyzing the processes of three different process software path planning algorithm and print the entity model,it is found that although three extrusion ways are different,but they all adopt the way of compound extrusion,it will maximize the advantages of offset extrusion and reciprocating linear extrusion,and the outside-in extrusion mode’surface quality is better.The design of interlayer coherent trajectory can increase the consistency of printing and make the product more holistic.By reasonably arranging path can improve the quality of the mode’s surface,reduce the empty path in the process of printing,reduce the“step effect”and the phenomenon of drawing,save printing time and dosage of consumables.
