3D-printed protected face shields for health care workers in Covid-19 pandemic.

• Eye-protecting devices are crucial to cut off virus transmission via conjunctiva. • 3D-printing devices inside hospital setting allows rapid and large-scale manufacture. • An ongoing dialogue in an interdisciplinary group allows iterative improvements. The coronavirus pandemic resulted in a shortage of protective equipment. To meet the request of eye-protecting devices, an interdisciplinary consortium involving practitioners, researchers, engineers and technicians developed and manufactured thousands of inexpensive 3D-printed face shields, inside hospital setting. This action leads to the concept of "concurrent, agile, and rapid engineering". [ABSTRACT FROM AUTHOR]
