1.0mm Thick PETG for Screen??
Hi all,
Has anyone tested 1.0mm thick PETG sheet for the screen? We are trying to deliver 100 face shields but are unable to source a good supply of 0.5mm PETG, just sellers on eBay and Amazon trying to make a quick buck.
I can get large sheets of 1.0mm, but have heard there can be issue with cracking. Can anyone confirm this??
Also, if we cannot use 1.0mm, can someone provide a good source of 0.5mm PETG in the UK that can supply quickly?
We have a laser cutter, so size is not a problem, just need a good reliable supplier for 100 masks worth of PETG.

Hi Mario87,
I have made 50 masks with 0.5mm PETG, with 2 sheets that have cracked near one of the holes, both repaired easily. I have so far made 37 masks with 1mm PETG, no cracks. The 1mm sheet is a bit stiffer, and you need a remix of the bottom reinforcement for 1mm sheet, but otherwise fine.
There is another bottom reinforcement solution suitable for both 0.5mm and 1mml shields, and only take 7 minutes each to print by designed by Hackbroetchen. Link is https://www.prusaprinters.org/prints/27801-easy-and-fast-bottom_reinforcement-alternative . I have tested them on 0.5 and 1mm shields.

Just to add, we can source 0.5mm PVC...would that even work??

We are using 10mil transparency film sheets from local office supply stores.

I'm using 0.8mm "PET Plastic Replacement for Picture Frame Glass" sheets; it's a little stiff but it's working great.
