Very cool idea…
Looks like the brand name stuff at least is made out of nylon, so it should be safe. http://www.smalleyandcompany.com/docs/msds/MSDS%20H088%200172.pdf
As to how well it cuts I can only imagine that focusing on the hooks would be an issue.
But maybe it melts fast enough that you don’t need accurate focus?
I think an experiment is in order post delivery!
I find it interesting that they have cut and engrave information for PVC and PVB, but no warnings of any kind associated with that info. I thought that hitting PVC with a laser was a huge no-no. Am I missing something here?
It is only a no-no if you are not set up to deal with the consequences.
In you house, not a good idea, in manufacturing environment it is just something to plan for.
They are making industrial tools, and I can certainly imagine a scenario where some factory wants to laser cut PVC and is willing to build the ventilation necessary to handle the resulting Chlorine emissions.
That makes sense. Still, if there is no warning about emissions for the PVC, it makes me wonder what else is in the list that is acceptable in an industrial situation but should not be considered acceptable for the casual 'Forger.
It is still a neat resource, with the huge caveat that many of the materials still need to be researched to make sure they are safe for us to use.
I can certainly see people looking at the web app, finding settings for engraving PVC pipe (for example), and assuming that means it is safe to do in the Glowforge.

I totally agree, and we should all be very circumspect about what we do with any new equipment!
For instance, I know from working with my father in his woodworking business that there are lots of hardwoods that are incredibly irritating to cut. If you have never experienced it yourself or heard about it you would think “hey it’s just wood”. I am willing to bet the same holds true for burning them in a glowforge.
Here is a few good references if you are concerned
@jkopel, I made your first post a wiki post, which means anyone can edit it and keep it up to date. If you find a new resource, reply to this thread so everyone knows where it came from, then you or someone else can add it here.
I’ve been going through the Synrad archives. So I normative about the vocabulary used in laser cutting and engraving. Not just materials but techniques. So, I thought trepanning was just to let loose evil spirits in the head. Fancy name for putting a hole in something during a production process. Excellent resources on the materials side. Most of the articles deal with much more powerful lasers than what we will get, but treat the same materials we are talking about here.
