I tried my hand at cutting Hobby Lobby craft felt today. Pretty good results after playing around with settings. Hobby Lobby had a variety of felt products. I researched craft felt and found that every kind I saw was Acrylic/Polyester. I am PRETTY SURE that these don’t contain any PVC, but did not do any burn tests and wasn’t able to confirm with Hobby Lobby’s website. OK - disclaimers over.
Here are two of the types I cut. The green is a fairly thick sheet. Sold at 9x12 inches for 79 cents a sheet. They had very thin felt also, but I didn’t pick any of that up. The white is adhesive backed felt. Also 9x12 and 99 cents a sheet.
I lied to the Glowforge and said it was veneer, but then set the manual cutting at 1% and speed at 140. It cut nicely. I also used a sacrificial piece of yardstick underneath. It seemed to cut out some of the “meltyness” (a new technical term) on the back of the acrylic/polyester material.
The green was quite thick for felt and some of the areas in between the center and “arms” kind of melted together. Probably a product of the small size of the cuts. I don’t think current Glowforge settings will allow much smaller cuts. The white adhesive backed felt cut very well. It’s not super soft, but I see cutting some fuzzy santa suits for christmas cards this year.
Here’s a shot of the thickness of the felt. The edges got kind of crispy and hardened, but all in all a pretty good job and something I could never have done otherwise.
Settings were .030 material thickness, 1% power and 140 speed. Your mileage may vary.
