Abstract

Herein, the effects of recycled polymers on the mechanical properties of additively manufactured specimens, specifically those derived by fused deposition modelling, are determined. The intention is to investigate how 3D-printing can be more sustainable and how recycled polymers compare against conventional ones. Initially, sustainability is discussed in general and more sustainable materials such as recycled filaments and biodegradable filaments are introduced. Subsequently, a comparison of the recycled filament recycled Polyethylene terephthalate (rePET) and a conventional Polyethylene terephthalate with glycol (PETG) filament is drawn upon their mechanical performance under tension, and the geometry and slicing strategy for the 3D-printed specimens is discussed. Finally, the outcomes from the experiments are compared against numerically determined results and conclusions are drawn.

增材制造的可持续性:探索再生PET长丝的机械潜力
在这里,回收聚合物对增材制造样品的机械性能的影响,特别是那些由熔融沉积模型导出的,被确定。其目的是研究如何使3d打印更具可持续性,以及回收聚合物与传统聚合物相比如何。首先,可持续发展是一般讨论和更可持续的材料,如再生长丝和可生物降解长丝介绍。随后,比较了再生长丝再生聚对苯二甲酸乙二醇酯(rePET)和传统聚对苯二甲酸乙二醇酯(PETG)长丝在张力下的机械性能,并讨论了3d打印样品的几何形状和切片策略。最后,将实验结果与数值计算结果进行比较,得出结论。
