Nowadays, COVID-19 also known as novel coronavirus has become a global pandemic by causing severe respiratory tract infections in humans without any definite treatment or vaccine. Therefore, disease control measures include slowing down or averting the transfer of this viral infection from person to person. Continuous efforts are carried out to avoid the transmission of this disease to frontline healthcare personnel using single-use personal protective equipment (PPE). However, a critical shortage in this equipment around the world is becoming an alarming concern. Therefore, it is vital to present a possible alternative to overcome the acute shortage of protective gear such as face masks against this infectious disease which can have universal accessibility and is easily available. Additive manufacturing (AM), also known as 3D printing, is a possible solution to overcome the shortage of protective gear and can play a vital role in supporting their conventional production supplies during this global pandemic situation. In this context, this paper provides a brief background study of COVID-19, its conventional preventive measure, and a detailed overview regarding the latest AM efforts including designers’ providers and makers in the 3D printing community. Moreover, numerous inquiries and questions such as technical factors, testing recommendations and characterization methods and biological concerns such as biocompatibility and sterilization for the AM manufactured medical devices are addressed in this paper. In the end, two examples of AM medical devices, i.e., face mask and Ambu bag ventilator, are presented and studied through numerical simulations.

如今，COVID-19（也称为新型冠状病毒）已成为全球流行病，在没有任何明确的治疗或疫苗的情况下引起人类严重呼吸道感染。因此，疾病控制措施包括减缓或避免这种病毒感染在人与人之间的传播。我们不断努力避免这种疾病传播给使用一次性个人防护装备（PPE）的一线医护人员。然而，全球范围内这种设备的严重短缺正在成为一个令人担忧的问题。因此，至关重要的是提出一种可能的替代方案，以克服针对这种传染病的防护装备（例如口罩）的严重短缺，这种防护装备可以普遍使用且易于获得。增材制造（AM），也称为3D打印，是解决防护装备短缺的一种可能的解决方案，并且可以在全球大流行期间在支持传统生产供应方面发挥至关重要的作用。在此背景下，本文对 COVID-19 及其传统预防措施进行了简要背景研究，并详细概述了 3D 打印社区中设计师、供应商和制造商等最新的增材制造工作。此外，本文还讨论了许多询问和问题，例如技术因素、测试建议和表征方法，以及增材制造医疗器械的生物相容性和灭菌等生物学问题。最后，通过数值模拟提出并研究了增材制造医疗设备的两个例子，即面罩和Ambu袋呼吸机。
