论文摘要
在COVID-19大流行期间，医疗设施开始使用3D印刷的PPE，这些PPE来自其自己的印刷实验室，制造商，大学和带有3D打印机的个人，以填补供应空白，因为传统制造的分布不够广泛，也不足以迅速以扩展到扩展需求。但是，迄今为止，此PPE仅限于低温，易于打印的热塑性塑料，这些塑料与高压灭菌不兼容，并且必须通过洗手方法进行灭菌。在本文中，我们提出了一种在常见的低成本3D打印机上打印抗温度的尼龙共聚物的方法。我们表明，所得部分可以在没有变形的情况下进行高压灭菌，并进行单轴拉伸测试，表明材料的高压量不会导致材料特性的大量降解。结果，我们证明了在低成本消费者3D打印机上生产可高压剂的PPE的能力，并且仅修改了。
During the COVID-19 pandemic, medical facilities began using 3D printed PPE sourced from their own print labs, makerspaces, universities, and individuals with 3D printers to fill the gaps in supply as traditional manufacturing was not widely enough distributed nor quick enough to scale to widespread spikes in demand. However, to date this PPE has been limited to low-temperature, easy to print thermoplastics which are not compatible with autoclave sterilization and must be sterilized by hand washing methods. Herein, we present a method for 3D printing a temperature resistant nylon copolymer on a common low-cost 3D printer. We show that the resulting parts can be autoclaved without deformation, and conduct uniaxial tensile testing showing that autoclaving the material does not result in substantial degradation of material properties. As a result, we demonstrate the capability to manufacture autoclavable PPE on low-cost consumer 3D printers with only minor modification.
