On April 4th, we gave six face shields to a local hospital. Not only does this provide them with desperately needed PPE, but it also gives us an opportunity to get feedback on different the different shield designs. Of the six prototypes, three used rivets to attach the shield, and 3 used a slotted opening in the headband. The shields were also a mixture of 3D printed headbands and silicone cast headbands.
The Supplyframe DesignLab graciously donated supplies and time to help us prototype and produce face shields. In particular, the DesignLab has a laser cutter which was used to test the laser cut face shield design. The headbands were cut out of acrylic, and the shields were cut out of PETG.
