A prototype face shield that Prothesia developed. 
This Faceshield is intended to be manufactured with laser cutting or die-cutting. 

For this prototype, the materials used are:

• PETG sheet 0.5mm of thickness.
• 16mm elastic strap to adjust the fit.

PETG is recommended but PVC and PET can work too.

The advantages of this design include:

• Good top, bottom and sides protection against droplets.
• Easy to clean
• Durable

The Faceshield is being tested by Tec Salud medical personnel in Monterrey, N.L. in Mexico. Getting good feedback.
