PETG (soda bottle plastic) also works
It's cheaper than lexan and has a lower sag temp
I've heard delrin can also be vacuum formed - but IIRC it's basically nylon and I don't think it's clear... But, it's much better at resistance to cracking like lexan (PETG being a little better than lexan).
We had to do this research last year for the HPV build (just passing that info along
)
