【摘要】 为确定3D打印鞋面结构的材料构成，并确保3D打印鞋面的最佳效果，讨论了以热塑性聚氨酯(TPU)、柔性聚乳酸(PLA)和聚乙烯醇(PVA)3种材料为主体的3D打印鞋面结构。通过对热塑性聚氨酯(TPU)和柔性聚乳酸(PLA)耗材进行扫描电镜、红外光谱、X射线衍射、差热分析、拉伸性能和弹性回复率测试分析，对3D打印支撑材料聚乙烯醇(PVA)进行扫描电镜、差热分析和溶解性能分析，探讨这3种材料的力学性能。结果表明：热塑性聚氨酯(TPU)和柔性聚乳酸(PLA)材料适合用于3D打印鞋面面料，聚乙烯醇(PVA)的物理形态良好，可用作3D打印支撑材料。更多还原

【Abstract】 In order to determine the material composition of the 3D printed shoe upper structure and to ensure the best results of 3D printed shoe uppers, the 3D printed shoe upper structure with thermoplastic polyurethane(TPU), flexible polylactic acid(PLA), and polyvinyl alcohol(PVA) as the main 3D printing materials are discussed, and the 3D printed thermoplastic polyurethane(TPU) and flexible polylactic acid(PLA) consumables are analyzed by scanning electron microscopy, infrared spectroscopy, IR, X-ray diffraction, differential thermal analysis, tensile properties and elastic recovery rate test analysis on 3D printed thermoplastic polyurethane(TPU) and flexible poly(lactic acid)(PLA) consumables, and scanning electron microscope(SEM), differential thermal analysis and solvency properties analysis on 3D printed support material poly(vinyl alcohol)(PVA), to explore the mechanical properties of these three materials. The results show that thermoplastic polyurethane(TPU) and flexible polylactic acid(PLA) materials are suitable for 3D printed shoe upper fabrics, and polyvinyl alcohol(PVA) can be used as a 3D printing support material in physical form.更多还原
