Impact of Masks Made by Additive Manufacturing during the Period of the Global COVID-19 Pandemic

3D printing technology made numerous contributions to the healthcare sector during the recent coronavirus 2019 pandemic (COVID-19). This review discusses some of these contributions of 3D printing that helped protect multiple lives during this health emergency and lists some of the key benefits of using 3D printing technology during an emergency over other traditional methods. This research confirms that 3D printing is very useful in times of severe supply shortages and excess demand. This review recognizes the collaborative approaches of individuals, entrepreneurs, academics, and companies that have helped form a global network to deliver 3D printed medical and nonmedical components, making additive manufacturing (3D printing) a representative alternative to produce ergonomic, cost-effective products and sustainable masks that reduce their environmental impact.
