The coronavirus disease 2019 (COVID-19) rapidly spread to over 180 countries and abruptly disrupted production rates and supply chains worldwide. Since then, 3D printing, also recognized as additive manufacturing (AM) and known to be a novel technique that uses layer-by-layer deposition of material to produce intricate 3D geometry, has been engaged in reducing the distress caused by the outbreak. During the early stages of this pandemic, shortages of personal protective equipment (PPE), including facemasks, shields, respirators, and other medical gear, were significantly answered by remotely 3D printing them. Amidst the growing testing requirements, 3D printing emerged as a potential and fast solution as a manufacturing process to meet production needs due to its flexibility, reliability, and rapid response capabilities. In the recent past, some other medical applications that have gained prominence in the scientific community include 3D-printed ventilator splitters, device components, and patient-specific products. Regarding non-medical applications, researchers have successfully developed contact-free devices to address the sanitary crisis in public places. This work aims to systematically review the applications of 3D printing or AM techniques that have been involved in producing various critical products essential to limit this deadly pandemic's progression.
2019年冠状病毒病（COVID-19）迅速蔓延至180多个国家，突然扰乱了全球的生产率和供应链。从那时起，3D打印，也被称为增材制造（AM），作为一种利用逐层沉积材料来制造复杂3D几何形状的新技术，已参与减轻疫情爆发所造成的困扰。在这场大流行的早期阶段，包括口罩、防护面罩、呼吸器和其他医疗装备在内的个人防护装备（PPE）短缺问题，通过远程3D打印这些装备得到了显著缓解。在不断增长的检测需求中，由于其灵活性、可靠性和快速响应能力，3D打印作为一种制造工艺，成为满足生产需求的一种潜在且快速的解决方案。最近，在科学界受到关注的其他一些医疗应用包括3D打印的呼吸机分流器、设备部件和定制患者产品。在非医疗应用方面，研究人员已成功开发出非接触式设备，以应对公共场所的卫生危机。这项工作旨在系统回顾3D打印或增材制造技术在生产各种关键产品中的应用，这些产品对于限制这场致命大流行的发展至关重要。
