I noticed that the laser manual lumps polycarbonate and PETG together as the same banned material however I think this may be a typo. PETG is a glycol modified PET (“polyethylene terephthalate”) and is not related to polycarbonate. Anyone have input on this? If it’s wrong then I will edit it but want to check in to see what people say.
I thought maybe PET(G) could be banned for the same reason that polycarbonate is banned (that it absorbs the IR laser light and cuts inefficiently resulting in soot/flames), but the spectra I’m pulling up on the internet for PET(G) seem to show decent transmission in the IR. Also people on the internet appear to be cutting it with IR lasers.
Whether PET/PETG is approved at NB is a separate issue but first I want to make sure it’s not banned…
