DIY Protective Mask with Activated Carbon Filter Against COVID-19: A Prototype Printed in Soft TPU 80A This innovative mask was printed without supports by Recreus, a Spanish company, using their proprietary soft TPU 80A material. The design allows for an interchangeable activated carbon filter, and what's more, it can be printed with Copper3D - MD Flex, a surgical filament developed by Formfutura Holland that contains nanoparticles capable of destroying up to 99.99% of viruses, bacteria, and microorganisms. Unlike conventional cotton masks, this material is not produced for mass production, but as Makers, we should at least consider its potential. The combination of an antibacterial material used in prostheses and an activated carbon filter makes this mask a fascinating scientific experiment. This DIY mask project is open-source, with all the files available on Thingiverse for anyone to develop or modify. The creator encourages users to print it at home using their own 3D printer. March 13, 2020 Update A new mask shape called "mask shape 02.stl" has been uploaded, which provides a better fit following the nose shape after functional testing. March 18, 2020 Update Regarding filters, please refer to the article on Smartairfilters for the best materials to use in DIY face masks against viruses. The recommended material is Gabardin Cotton with a fine texture. Copper3D, the brand behind the antibacterial filament, has designed and shared its own version of a protective anti-COVID mask.

April 1, 2020 Update A small clip to mount elastic ribbons has been designed, which is available in the file "fermo elastico.stl".
