PETG vs CPE?

[eightlines]

Is CPE an acceptable alternative to PETG?

Of course it is, but in my opinion it seems overkill. It costs way more, and the added benefits of CPE will not be of much benefit for this particular application. Heck, I think even PETG is overkill. I think PLA will be just fine for this application. Sure, it's more brittle, but it costs less, and prints faster, so you can whip up more face shields in less time. Not to mention the lifespan of face shields is short anyways and needs to be replaced regularly. At least that's what I heard, I'm not sure.
