I want to lasercut a green LEGO baseplate for a project, but cannot cut a plastic with the laser if it contains PVC or Vinyl.
Does anyone know if the green baseplates are free from these materials.

LEGO baseplates are made from ABS plastic, like most of the opaque rigid plastic LEGO elements since 1970. ABS is a thermoplastic consisting of a styrene monomer with the addition of an acrylonitrile momomer and a butadiene monomer. There is no PVC or vinyl present.
I suggest reviewing this thread for more on laser-cutting ABS. It is not a trivial matter to get a good result.
Edited to add: In response to a query from a "safe toy" website, LEGO categorically stated that they do not use PVC in any of their products except in rare instances like electrical wiring insulation.
They are made from ABS injected into a mold. I actually got to see Legos made at legoland, a truly amazing experience!
