Masks
The initial design and validation has been done with masks printed using sintering 3D printing techniques that ensure no leaks between the possible contaminated environment and the inside of the mask.
The final validations have been made with an injection version of size L, which complies with the UNE-EN 1827, UNE-EN 143 and UNE-EN 149 standards.
For other sizes, 3D models are available that can be manufactured in 3D printing by sintering.
The mask is designed to minimize resistance to exhalation / inhalation, thus increasing user comfort.
The project has completed the design and validation of masks with FFFP2 and FFP3 filters.
