Abstract

Background: In 2020, the severe acute respiratory syndrome coronavirus 2 pandemic caused serious concerns about the availability of face masks. This paper studies the technical feasibility of user-specific face mask production by 3D printing and the effectiveness of these masks. Material & methods: Six different face mask designs were produced by 3D printing and tested by subjective experimenter evaluation and using a respirator fit testing kit. Results were compared with the requirements as given for standard protective face masks. Results: None of the printed masks came anywhere near the required standards for personal protective gear. Conclusion: In spite of their euphoric presentation in the press, none of the currently advertised 3D printed mask designs are suitable as reliable personal protective equipment.
在严重急性呼吸综合征冠状病毒大流行期间,广泛使用3D打印制造口罩的潜在风险
背景:2020年,严重急性呼吸综合征冠状病毒大流行引发了人们对口罩供应的严重担忧。本文研究了3D打印生产用户专用口罩的技术可行性和口罩的有效性。材料与方法:采用3D打印技术制作六种不同的口罩设计,并通过主观实验者评估和使用呼吸器适配测试试剂盒进行测试。结果与标准防护口罩的要求进行了比较。结果:打印的口罩都没有达到个人防护装备的要求标准。结论:尽管媒体上的3D打印口罩设计令人兴奋,但目前宣传的3D打印口罩设计都不适合作为可靠的个人防护装备。
