Lennon Rodgers, director of the UW-Madison College of Engineering’s Grainger Engineering Design Innovation Lab, said that two weeks after UW Health asked him in early March if he could make 1,000 face shields, companies from around the country were contacting the university to use its design. “You think elastic is easy to get, or foam; it is, if you want to make 1,000 or even 10,000 (face shields),” he said. “But when you’re talking millions, it’s truckloads upon truckloads of material.”
