Capitalism!

“Business Insider Italia explains that even though the original manufacturer was unable to supply the part, it refused to share the relevant 3D file with Fracassi to help him print the valve. It even went so far as to threaten him for patent infringement if he tried to do so on his own. Since lives were at stake, he went ahead anyway, creating the 3D file from scratch. According to the Metro article, he produced an initial batch of ten, and then 100 more, all for free. Fracassi admits that his 3D-printed versions might not be very durable or re-usable. But when it’s possible to make replacements so cheaply—each 3D-printed part costs just one euro, or roughly a dollar—that isn’t a problem. At least it wouldn’t be, except for that threat of legal action, which is also why Fracassi doesn’t dare share his 3D file with other hospitals, despite their desperate need for these valves.”
