The shortage of personal protective equipment (PPE) available to health care professionals has become increasingly problematic as Covid-19 cases continue to surge. The sheer volume of PPE needed to keep doctors, nurses, and their patients safe in this crisis is daunting — for example, tens of millions of disposable face shields will be needed nationwide each month. This week, a team from MIT launched mass manufacturing of a new technique to meet the high demand for disposable face shields.
The single piece face shield design will be made using a process known as die cutting. Machines will cut the design from thousands of flat sheets per hour. Once boxes of these flat sheets arrive at hospitals, health care professionals can quickly fold them into three-dimensional face shields before adjusting for their faces.
“These face shields have to be made rapidly and at low cost because they need to be disposable,” explains Martin Culpepper, professor of mechanical engineering, director of Project Manus, and a member of MIT’s governance team on manufacturing opportunities for Covid-19. “Our technique combines low-cost materials with a high-rate manufacturing that has the potential of meeting the need for face shields nationwide.”
