摘　　要：在熔融沉积成型(Fused Deposition Modeling,FDM)的工艺过程中,有很多工艺参数影响着其成型精度,着重分析了挤出速度(A)、扫描速度(B)、层厚(C)和喷头温度(D)这4个参数对FDM工艺成型精度的影响。通过正交试验得出各指标最优时这些工艺参数的组合。利用矩阵分析法对多指标正交试验进行优化,从而确定了各个因素对试验指标值影响的主次顺序为C、D、A、B,最优组合为A_2B_2C_2D_3。试验结果表明该方法能有效提高成型件的综合性能。In the process of Fused Deposition Modeling （FDM）, the dimensional accuracy was affected by many technical parameters. Extrusion speed （ A ）, scanning speed （ B ）, layer thickness （C） and nozzle temperature （D） were discussed to analyze their impacts on the dimensional accuracy of the parts. The optimal combination could be obtained by the orthogonal experiment. The matrix method was used to optimize the multi-target orthogonal experiment, then the sequence of the every factor for the experiment index value could be determined by C,D ,A, B, and the optimal combination also could be obtained by A2 B2 C2 D3. The experi- ment result showed that the method could effectively improve the comprehensive performance of parts.
