I found this page that has a pretty good list of materials, and what happens when you laser cut them.
There has been a ton of talk in the forums about particular materials, but I’ve noticed its getting a little repetitive (yes, don’t cut pvc) . It would be great to get that condensed into a single go-to area. I thought this list was a pretty good start. Add some info below if you thinks its missing materials. Then in the future we can direct people to this series of posts, rather than all over the forums.
(PS, Their laser is somewhere between 10 - 60 W so it should be similar to what we are getting)
