晶格结构是一种细胞材料，可以实现多种有前景的物理特性。增材制造（AM）缓解了制造复杂几何形状的晶格结构的难度。然而，增材制造制造的晶格结构的质量仍然需要改进。本文采用田口法研究了熔融沉积成型（FDM）工艺参数对晶格结构的影响。信噪比分析用于寻找提高印刷质量的最佳工艺参数，方差分析提供了本文分析的各种因素的显着性排名。研究发现，对于水平和倾斜支柱，每个工艺参数的最佳水平和重要性有所不同。此外，压缩试验研究了工艺参数对晶格结构机械性能的影响。结果表明，通过打印质量优化的工艺参数还可以提高这些晶格结构的弹性模量和极限强度。 (C) 2017 Elsevier B.V. 保留所有权利。
The lattice structure is a type of cellular material that can achieve a variety of promising physical properties. Additive Manufacturing (AM) has relieved the difficulty of fabricating lattice structures with complex geometries. However, the quality of the AM fabricated lattice structure still needs improvement. In this paper, the influence of parameters of the Fused Deposition Modeling (FDM) process on lattice structures was investigated by the Taguchi method. S/N ratio analysis was used to find the optimal process parameters that improve the printing quality, and ANOVA provided a significance ranking of the various factors analyzed in this paper. It was found that the optimum level and significance of each process parameter vary for horizontal and inclined struts. In addition, compression tests investigate the influence of process parameters on the mechanical properties of lattice structures. The results show that process parameters optimized by print quality can also improve the elastic modulus and the ultimate strength of these lattice structures. (C) 2017 Elsevier B.V.
