How about engraving Corian?

What if I'm using air assist, do these warnings still apply?

Of course.

Yes. Even if you have a sealed enclosure that events to the outside, or goes through an air scrubber. Some of these materials could damage your laser or the frame simply from the vaporized materials.

I saved the list to a PDF for printing.
Welcome to it.

RE: Material with Sticky Glue Backing

... would this include (as shown on many video tutorials) masking tape? What about about paper with a light spay of repositionable adhesive, such as Elmer's Craft Bond or Scotch Spay Mount ... I was actually planning to do this!!!

thanks!

Also, to follow up on this ... Plywood has glue between layers. My understanding is it is typically a PVC glue often containing formaldahide. Is cutting that a potential hazard **TO THE LENS** (with or without air assist) also? (obviously we wouldn't want to breathe it!)

I'm specifically asking this question because there are many PLYWOODS sold targeting for use with lasers (diode or other.)

TIA,

This is good information! I am a noob here and a noob with laser etching and cutting. So much to learn. I was engraving/marking adhesive backed cork. I was not cutting it or going deep enough to reach the adhesive but I'm not sure if it's safe to just mark or engrave the cork.

I knew that many materials were dangerous to cut or engrave, but I never found a list, thank you for the info.
