This article introduces a multi-objective optimization approach for determining the best 3D printing parameters (layer thickness and infill percentage) to efficiently produce PLA and ABS parts, extensively analyzing mechanical behavior under tests for different traits such as tensile strength, compression, flexural, impact, and hardness. The value analysis method is used to optimize settings that balance use value (- represented by mechanical characteristics) and production cost (). Findings reveal that the infill percentage significantly influences the ratio for tensile, compression, and hardness tests, while flexural tests are influenced by layer thickness. Impact strength is influenced nearly equally by both factors, with material-specific variations. The desirability function proved useful for optimizing processes with multiple responses, identifying the optimal parameters for the FDM process: a layer thickness of 0.15 mm with 100% infill percentage for PLA, a layer thickness of 0.20 mm with 100% infill percentage for annealed PLA, and a layer thickness of 0.15 mm with 100% infill percentage for ABS. Overall, this study guides efficient 3D printing parameter selection through a technical-economic optimization based on value analysis.
本文介绍了一种多目标优化方法，用于确定最佳的3D打印参数（层厚和填充率），以高效生产聚乳酸（PLA）和丙烯腈-丁二烯-苯乙烯共聚物（ABS）零件，并对不同特性（如拉伸强度、压缩、弯曲、冲击和硬度）测试下的力学行为进行了广泛分析。采用价值分析方法来优化设置，以平衡使用价值（由力学特性表示）和生产成本。研究结果表明，填充率对拉伸、压缩和硬度测试的 比率有显著影响，而弯曲测试受层厚影响。冲击强度受这两个因素的影响几乎相同，但存在材料特定的差异。合意函数被证明对优化具有多个响应的过程很有用，确定了熔融沉积成型（FDM）工艺的最佳参数：PLA的层厚为0.15毫米，填充率为100%；退火PLA的层厚为0.20毫米，填充率为100%；ABS的层厚为0.15毫米，填充率为100%。总体而言，本研究通过基于价值分析的技术经济优化指导了高效的3D打印参数选择。
