全球冠状病毒病（COVID-19）大流行导致个人防护装备（PPE）在国际上短缺，传统供应链无法科普巨大需求，导致严重短缺。一些开放和众包举措试图通过使用熔丝制造（FFF）等增材制造技术生产防护面罩等设备来解决这一短缺。本文报道了使用大规模增材制造（LSAM）来生产防护面罩的主要热塑性部件的设计和制造防护面罩的过程。LSAM在桥梁制造场景中提供了比其他增材制造技术更大的优势，作为原型和大规模生产技术（如注塑成型）之间的真正过渡。在生产COVID-19面罩的背景下，与使用另一种增材制造技术通常需要1 - 2小时相比，在5分钟内生产优化组件的能力意味着可以以最少的人员配备快速实现大量生产。
The global coronavirus disease (COVID)-19 pandemic has led to an international shortage of personal protective equipment (PPE), with traditional supply chains unable to cope with the significant demand leading to critical shortfalls. A number of open and crowdsourcing initiatives have sought to address this shortfall by producing equipment such as protective face shields using additive manufacturing techniques such as fused filament fabrication (FFF). This paper reports the process of designing and manufacturing protective face shields using large-scale additive manufacturing (LSAM) to produce the major thermoplastic components of the face shield. LSAM offers significant advantages over other additive manufacturing technologies in bridge manufacturing scenarios as a true transition between prototypes and mass production techniques such as injection molding. In the context of production of COVID-19 face shields, the ability to produce the optimized components in under 5 min compared to what would typically take 1 – 2 h using another additive manufacturing technologies meant that significant production volume could be achieved rapidly with minimal staffing.
