Theres discarded signs at work that seems to be sublimated graphics on acrylic. Anyone in the sign making industry out there who could confirm if sign plastic is likely laser safe acrylic or if the standard plastic used in this type of signage has PVC in it?
It’s so hard to see plastic that could be used o a laser project if it’s safe. I would only cut, not planning to engrave
No way to know without testing, but in researching alternatives to acrylic sheet, it seems ABS and PVC are MUCH cheaper but with similar (non-laser) qualities, so I would guess it’s one of those.
