I think I would be ok risking it, assuming you’re venting outside and so on. I checked the MSDS and it lists “No known significant effects or critical hazards” if you ingest it. Of course that doesn’t make it a good idea to eat it, and that doesn’t mean nothing noxious can be released if it’s burned, but I’m saying if you can consume it, I’d be surprised if it were super hazardous to burn. That said, I experimented with a 3D engrave today on some basswood which had been joined with wood glue. Of course, the glue doesn’t disintegrate at the same rate as wood, so I have a nice raised glue line running through the middle of my engrave… Best of luck!
I have no idea. No idea of the content released from the quantity of material being burned. No idea of the content that leads to damage. Etc. just thought I’d point out a potential risk.
It’s something I’d probably stay away from. A lot of stuff, like formaldehyde in a lot of plywood’s, doesn’t bother me so much, because my venting is pretty good. But I’d hate to do something corrosive to the machine.
When researching Titebond glues, I noticed on the website here under technical highlights section it says Titebond Original is a type of “aliphatic resin” which doesn’t sound like something that should be lasered. So doesn’t look like you can use original titebond either?
I don’t know if this is entirely relevant but on the topic of wood glue, I use Gorilla Wood Glue for most of my projects (we don’t get Titebond easily in the UK). I have checked the information on this and it says it is “Polyvinyl Acetate Polymer product in water” which doesn’t sound like it should go in the laser at all. I found this information here on the Gorilla Glue website. So I only assume that this is not safe?
