Coronavirus: 3D printers save hospital with valves

Comes this update:
A medical device manufacturer has threatened to sue

"Update, March 18th 3:30PM ET: A group of Italian volunteers distributed 3D-printed versions of a vital medical device — but it’s unclear if the original manufacturer threatened a legal crackdown. As we reported earlier, Cristian Fracassi and Alessandro Romaioli used their 3D printer to create unofficial copies of a patented valve, which was in short supply at Italian hospitals. Business Insider Italia quoted Massimo Temporelli, the Italian professor who recruited the pair, saying that the device maker threatened them with an infringement claim."
