RE: cutting glue backed substances what about using masking tape or vinyl rolls that we see people using on youtube

Is PET (polyethylene Terepthalate) safe to cut with the laser. I want to cut laminated card stock to make playing cards.

I read through this thread and didn't see it mentioned anywhere hopefully I didn't over look it but, what about PU (polyurethane) leather? a google search comes up with lot's of conflicting information but, what I am taking away from it is, yes it will engrave but it can/will emit toxic fumes. although again conflicting information about how toxic and in what amounts? anyway just wondering if anyone here has solid information or personal experience with it.

I see on the list that we can't/shouldn't cut cork with glue backing but what about etching on the cork side but not deep enough to penetrate the glue? Like 4000/18 power? Would this be safe or not worth the risk? Not looking for a deep or very dark burn just enough to see the logo.

I bought these below to adhere to the bottom side of wood coasters but would like to engrave my logo on them.


Thanks in advance for your advice

That's fine, no problem. But remember that everything you engrave or cut is toxic to some degree. If you can smell it, it's bad. So make sure you have good ventilation when using your laser. Preferably an enclosure venting to the outdoors.

Wow, thank you so much for this! I actually had a lot of these concerns and didn't find anything else online. This site needs to be front and center on Google!

Any known issues engraving luxury vinyl flooring used for coasters?

Yes! It is really GOOD at setting off every smoke detector in your home! It is also a vinyl, which apparently gives off Chlorine Gas, which can kill you. I guess I will have to invest in a water jet for these laser-UNfriendly materials.

I have an enclosure that I built, it has a hinged plexiglass lid and a 4" vent hole. I have a 4" duct fan and a carbon filter. I have never had a smoke or smell problem. I hope this helps.
