Safe materials reference

I was just browsing r/lasercutting and found a link to the Dallas Maker Space reference for laser material safety. They mention at one point that their laser is IR, so I’m wondering if this is a good reference to use for the Engravinator too. Does it look solid, and/or is there a better one?

There are some materials on there that the Engravinator just won’t even really touch because UV doesn’t work for it - but otherwise, in terms of safe / not safe, yeah - I use that reference all the time :slight_smile:
