No masks, but you hold 2/2

In addition to respiratory masks, 3D printers make transparent face masks to protect breathing. The most widespread model was from the Czech inventor Joseph Pruša (Josef Průša) .

The project for creating this mask, called Prusa Protective Face Shield , is distributed under a free license, developed in collaboration with the Czech Ministry of Health in three days and 12 prototypes, and continues to be developed and tested. According to Joseph, 3000 copies of face masks are printed on his farm daily.

In response to the lack of protective clothing for medical personnel in the current pandemic situation, Joseph Pruša and his company Prusa Research, a 3D printer company based in the Czech capital of Prague, quickly developed and began mass production of protective face masks. By March 28, more than 20,000 masks were printed and donated to doctors and other professionals, and there are requests for another 90,000. The

lack of protection is global, so anyone with a 3D printer can help. The global 3D printing community is becoming the driving force for protective clothing for those who need it most.

The face shield design is completely open and free to use and modify. In addition, readily available and inexpensive materials are used. Joseph Pruša asks for help in disseminating information or even joining the collective efforts of a community that can help thousands of people in need.

Contact facilities in your area and ask them if they need extra protective clothing. This is not only about hospitals and other first aid services, such as police and firefighters, but also about nursing homes, dentists or just grocery store employees - in other words, you can offer your help to all those who now have to stay at work and be in contact with many other people during the crisis.


We emphasize once again that the protective face mask was developed in three days in cooperation with the Ministry of Health of the Czech Republic, was approved for distribution, and is modified according to the recommendations of doctors. On March 27, Linus Tech Tips received 30 printers from Prusa Research and joined the production, from the project website the print files were downloaded 100,000 times.

On the project website there are not only all the files for printing and cutting, but also disinfection instructions, assembly instructions, more than 80 modifications from the community, assemblies for “night printing”.

And now the question is: what do we have in Russia? Almost nothing. Doctors need, but they can only purchase and use what has the status of a medical device. And to get this status, you need a year of time and a lot of money and nerves.

This is what a visor mask looks like with an enlarged visor shape (version for dentists), the print time is about 2 and a half hours, the protective visor is cut out of polycarbonate with a 0.5 mm laser per minute. The cost of manufacturing according to our estimates for a small batch of 500 rubles, but how to calculate the cost in terms of the forced closure of all production for the holidays with quarantine is not clear.
