摘　　要：研究了增减材复合制造加工熔融沉积成型(fused deposition modeling, FDM)薄壁零件的方法。结合增材制造和减材制造,改造传统独立双喷头3D打印机,修改右侧喷头为数控铣刀,在3D打印模型切片时对模型外轮廓进行识别和处理,生成数控加工代码,自动集成到3D打印G代码中,可对薄壁零件进行直接打印,并获得高精度的表面质量。对于薄壁复杂结构塑料零件的加工,通过改造的增减材打印机可以全自动生成复合加工G代码,大大提高了增减材复合制造的效率。In this paper,the method of manufacturing FDM thin-walled parts by adding and subtracting materials is studied.The traditional independent double nozzle 3D printer is reformed by combining additive manufacturing and material reduction manufacturing.The right nozzle is modified as NC milling cutter.When 3D printing model slices,the contour of the model is identified and processed to generate NC machining code,which is automatically integrated into 3D printing G code.The thin-walled parts can be directly printed and high-precision surface quality can be obtained.For the processing of thin-walled and complex structure plastic parts,the G code of composite processing can be generated automatically by the modified additive printer,which greatly improves the efficiency of additive and additive composite manufacturing.
