Development of mask design as personal protective equipment through 3D printing.

This project aimed to develop an innovative mask design, aided by 3D printing technology that was able to protect its wearers against virus infection. The project was motivated with the intention of helping to fight Covid-19, but that its use was extensive as an option to N95 and similar masks, already on the market, even after the pandemic. Whose main design objective was that the mask had a sealing efficiency based on a half-face mask and that it could be used in conjunction with masks made of antiviral fabrics, such as, for example, a surgical mask that has its filtering capacity already tested and approved and, which would be the filter element of the mask. The mask was also intended to be reusable so that it could be washed for cleaning, with only the fabric filter element being disposable.
