Did you put a fusible on the back to assist with applique? It looks too thin for needle-turn, and seems too delicate for sewing around enough of the edges without fusible. I’m interested in how the fusible would stand up to the laser. I’d think it would cut cleanly and the laser would not deposit enough heat to activate the fusible or melt it back or anything, but It would be nice to see it.
It’s a roll of paper masking tape that I purchased from Signmax. It is laserable.
I’m using the Signmax paper tape, but as soon as that roll is gone, I’m going to try to find another brand that has better adhesion. This one will pull up when the air assist hits an edge that’s hanging out over the material, and it can literally peel it back.
It actually presents a fire hazard if you don’t get it stuck down thoroughly. If it were to jam up under the beam…not good.
Okay, I ironed some Heat-n-Bond Ultra Hold onto the back of a piece of the fabric and ran another cut…
It turned out fine, but the cut didn’t go all the way through the paper on the back of the fusible webbing, so when that was peeled off, the fabric piece was released. (It’s fine - it’s eventually what you do with it anyway.)
One thing you do have to be a little careful about with Heat-N-Bond, they have a bunch of different kinds of fusible webbing, and one of them is a vinyl webbing. I would not use that one without checking it out first to see if it is safe to laser. (Vinyls that contain chloride are NOT safe, so as a rule, I just avoid vinyls.)
I think you are going to have to do a little experimenting. Start with power of 1 or 2 and work up. Start with a fast speed like 500. Make sure the fabric is held down securely so cut pieces don’t fly into the path of the laser.
There is a fair amount of variability in fabrics. You are really best off doing some tests with the fabric you are using. This is a popular method (though you might want to enlarge a little for fabric):
The Material Test proved to be wonderful. We cut 30 sets of a four-part design using Batik fabric on Heat and Bond UltraHold using a speed of 500 and power of 45. This cut thorugh the fabrid and the Heat and Bond and mostly through the paper backer, leaving the parts very lightly attached and not blowing in the wind. The bigger parts separated from the scrap very easily. The smaller perts we left together and will remove them as needed. We are very, very happy with our purchase. It is miles ahead of our current cutter, a Silver Bullet, and much easier to use. We weren’t sure if we would part with the Silver Bullet prior to trying our Glowforge, but there is no question now that we no longer need it. Thank you for your help evermorian.
