Only model approved by the Defense Innovation Agency(in front of nearly 1000 other visor proposals) PROFASTER ALPHA is a printable visor support from 10' on an FDM 3D printer with 0.4mm nozzle, from 170 mm platen, and stackable. The visor thus created, ultra-light (5.5 g), can be closed at the level of the forehead, thus offering complete protection.

Model deposited and offered as a file under Creative Commons CC BY-NC-ND license, a deliberate choice in the particular context of the Covid-19 crisis, PROFASTER ALPHA allows both the rapid manufacture of large quantities of visors (up to 120_cc781905- 5cde-3194-bb3b-136bad5cf58d_/ day with 1 printer), and to provide additional protection from above with no tools other than a hole punch and a pair of scissors.

The protection offered then meets the needs of French or foreign hospital personnel where protection on the top is recommended or even required, without compromising on the ease of production and assembly, and with an ergonomic shape based on precise biometric data.
