Additive manufacturing or 3D printing consists of the manufacture of a three-dimensional object by superimposing successive layers of material.
Although the first prototypes are from 1976, it will not be until 2003 that 3D printing begins to become popular, which leads to an improvement in the quality and lower prices of the devices.
Although at the beginning practically all 3D printers used resins or plastic polymers, today it can be printed with practically any material.
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

In the news that I am telling you today, the Chilean manufacturer Copper3D, has just released an open source file for a 3D printable N95 mask.
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.
This mask has been designed to provide respiratory protection with a filtration efficiency level of 95%, against particles in the air.
According to the company, the project involves some scientists who have been in charge of verifying the effectiveness, at the moment the patent is pending and I suppose that some other process is pending, but if the coronavirus thing becomes dull it can always help.
