There have been lots of discussions about materials.
With fabric, it seems reasonable that the laser CAN cut most of them; but results will vary by fabric and some experimentation is probably warranted…
HOWEVER
There are materials that you certainly should not put in your laser due to the exhaust. You don’t want to kill yourself or your family, you don’t want to destroy your laser, and you don’t really want to burn anything down.
This thread seems to indicate that polyurethane is safe, and you can find references to polyester, as well.
I’m not an expert; but I expect you may be fine to cut your diapers on the glowforge. And, added bonus, the burned/melted edges should naturally resist unraveling.
Then, to scan patterns, edit, and cut… yes. I haven’t seen it done; but it should be lovely, provided it fits on the bed. This is a serious use case for the pass through, and probably one of the points over which I’ll wish I had sprung for a pro.
