Protohaven has a design for a laser cuttable face shield from PETG sheet here: https://www.protohaven.org/proto-shield/
This is getting good reviews, and Nathan at MSU says they are wanted. I’ve been playing with the design to figure out how much material we’ll need.
There are two different thicknesses called fo: 0.060" for the headband, and 0.020" for the visor. Our laser cutter dimensions are 700mm x 500mm.
For the visor, we can only get 4 on the bed at once. A 500mm x 500mm (20in x 20in). This is the 0.020" thickness.
For the band, 10 copies will fit on a 420mm x 600mm (16 5/8" x 24"). Or 12 copies on a 420mm x 700mm (16 5/8" x 27 5/8") This is the 0.060" thickness.
If anyone else wants to look at the design and figure something out, please do.
Now we need to find some material. I’m willing to put some money into this. This material isn’t the cheapest thing, but it’s not exorbitant.
