3D Printing During COVID-19: Challenges and Possible Solutions

The COVID-19 pandemic has led to the imminent collapse of medical supply chains across global economies at an unprecedented scale. Essential supplies such as personnel protective equipment (PPE), ventilator components, and face shields have witnessed a continuous rise in demand and eventually boost the role of 3D printing. Over the months following the spread of the pandemic, 3D printed alternatives of many medical devices were made more accessible to hospitals, mostly by community-sourced design and fabrication. However, with the high volume usage of additive methodologies, several challenges associated with the design, manufacturing, and deployment of medical products have now been brought to further attention. In this work, a systematic evaluation of such challenges along with few possible solutions are presented. The pandemic and its effects on the industry are introduced in the context of disruptions caused across the supply chains. The role of additive manufacturing to counter these effects is presented with an introduction of the technology itself. Employing 3D printed products to address the shortages of healthcare equipment are mentioned and visualized. Thereafter, a central discussion is followed on the issues arising from the shift in production methodology of such medical devices—from conventional manufacturing to additive one. The problems are highlighted by discussing two important types of COVID-19 related 3D printed medical equipments—mechanical ventilators and PPEs. Thereafter, few possible solution methodologies are discussed as case studies of two particular instances of having such problems. Finally, a conclusion is drawn to solve the issues raised using similar solutions followed by future opportunities.
