摘　　要：针对熔融沉积制造(fused deposition manufacturing,FDM)零件成型后存在抗压缩性能低下的问题,以层片厚度、填充方式、打印质量和材料四个方面进行实验研究。将四种因素进行充分组合,选取具有代表性且均匀分布的试样,建立合理的正交实验表,采用田口分析对数据进行处理,探讨每种因素对FDM零件抗压缩力学性能的影响程度,将其进行排序,通过信噪比图选取最优参数组合方式。实验表明:影响FDM零件抗压缩力学性能程度由大到小依次为层片厚度、材料种类、填充方式和打印质量,四种因素最优的组合方式为层片厚度为0.1 mm,填充度为99%,材料为ABS+,打印质量采用默认方式。Aiming at the problem of low compression resistance of FDM parts after forming,the experimental research is carried out in four aspects:lamination thickness,filling method,printing quality and materials.Four factors are fully combined,representative and evenly distributed samples are selected;a reasonable orthogonal experimental table is established;data is processed by Taguchi analysis;the influence degree of each factor on the mechanical properties of FDM parts is discussed,and sorted,and the optimal parameter combination mode is selected through the signal-to-noise ratio diagram.The experimental results show that the degree of influence on the mechanical properties of FDM parts is in the order of lamination thickness,material type,filling method and printing quality.The optimal combination of the four factors is that the lamination thickness is 0.1mm,the filling degree is 99%,the material is ABS+,and the printing quality adopts the default mode.
