Abstract

In this research we present a novel technique to develop high ductility and drapeability 3D printed textiles by systematically controlling infill patterns (gyroid and rectilinear) across infill orientations (45°, 60°, 90°) and extrusion rates (60%, 80%, 100%). Using SEM, drapeability bending tests, and mechanical grab tests, we demonstrate for the first time 3D printed bio-based textiles with enhanced ductility and drapeability, while maintaining mechanical strength properties. Our novel approach can produce textiles with 91.4% reduction in bending length while maintaining mechanical strength, reduction in material use by as much as 40%, and a reduction in printing time by 50%. Therefore, this research presents a new approach to control several competing design objectives to 3D print sustainable bio-based textiles.

可垂性和弹性3D打印聚乳酸（PLA）纺织品

在这项研究中，我们提出了一种新技术，通过系统地控制填充图案（旋转和直线）在填充方向（45°，60°，90°）和挤出率（60%,80%,100%）来开发高延展性和悬垂性的3D打印纺织品。利用扫描电镜、可垂性弯曲测试和机械抓取测试，我们首次展示了3D打印生物基纺织品具有增强的延展性和可垂性，同时保持机械强度性能。我们的新方法可以在保持机械强度的情况下生产出弯曲长度减少91.4%的纺织品，减少多达40%的材料使用，减少50%的印刷时间。因此，本研究提出了一种新的方法来控制3D打印可持续生物基纺织品的几个相互竞争的设计目标。
