I was about to order a bit of 1.5 mm polycarbonate sheet to laser cut a replacement instrument cluster 'glass' for my JCB 803. Then I realised laser cutting is a no no with polycarbonate - apparently the cut is not very good leaving brown edges, and it gives off toxic fumes
Acrylic / Perspex works well but scratches easily (I've just cut one from a 3 mm off cut to prove the size)
PetG is easily available but apparently scratches easily
Pet is much the same
So what scratch resistant plastics are easily available in the 1.5 mm thickness that can be laser cut and are scratch resistant?
(I only need 100 mm square for this job but no doubt the same criteria will crop up in the future so I don't mind buying a reasonable sized bit.)
