The recent decline in available personal protective equipment (PPE) due to the novel coronavirus (COVID-19) pandemic has given rise to a host of three-dimensional (3D) printed prototypes for facemask and respirator units. Many of these models have been made open access and publicly available for printing and use, and have been promoted by various media outlets. Although these desktop 3D printing measures have provided a possible venue for success in providing homemade and cost-effective PPE to health care workers, the rapid dissemination of these prototypes has been performed without reproducible methods of standardization and vetted safety in use. Although these methods have not been sanctioned by authoritative organizations as viable production approaches to address the PPE shortage, a concerted effort within the 3D printing community to adhere to scientific methodology and organized research efforts has the potential to provide a solution to this critical issue.

COVID-19 危机中三维打印个人防护装备的注意事项

由于新型冠状病毒 (COVID-19) 大流行，最近可用的个人防护设备 (PPE) 有所减少，因此出现了大量用于面罩和呼吸器装置的三维 (3D) 打印原型。其中许多模型已开放获取并可供公众印刷和使用，并得到各种媒体的推广。尽管这些桌面 3D 打印措施为成功地为医护人员提供自制且具有成本效益的 PPE 提供了可能的场所，但这些原型的快速传播是在没有可重复的标准化方法和经过审查的使用安全性的情况下进行的。尽管这些方法尚未被权威组织认可为解决 PPE 短缺的可行生产方法，
