Toys, houses, jewelry, pizza, machinery parts, prosthetics, hamburgers and even organs, can be created by 3D printing just by having the plans for its construction
This is part of their "Hack The Pandemic" initiative that aims to mobilize all machine manufacturers, fablabs, etc. to create these masks, for hospitals and health professionals.
The file is open source which implies that anyone with a 3D printer in addition to specialized centers can print it for their use.
