My classroom at work has a industrial lasercutting machine. Used it to cut Icarex sail cloth for a trickkite build.
Very handy. The panel drawing (DXF) go right into the machine. No more template printing and cutting by hand.
The edges are perfectly sealed and all the panels are exactly equal. Also possible to cut multiple layers. I also used it to cut out the dacron reinforcements.
Works like a charm.

When multiple layers are hot-knifed the edges get fused together. Does that happen with the laser cutter?

This machine including air filtration device was about 17.000,- but i've seen building kits of desktop models for a few hundred bucks allready.

I tried with 2 layers and they didn't fuse. Speed and laser power are adjustable and it takes some testing to get the right settings.

Mmmmmm...Here's a wild idea. Toward the end of your video you show your cut pieces arranged as you will sew them and so now I am wondering could you adjust the laser to fuse them together rather than sewing them?  Undecided

Well, i guess you'll need some kind of pressure applied to the fabric to fuse it. For me it's not really an issue since i really like the way stitching looks in a sail.

Neat!

I've seen a "desktop" size laser cutter (for paper, cloth, thin wood) with like a 12" platform that was not too costly, and thought "too bad it's so small..."

The desk-top unit Kareloh linked too can be expanded to 1m^2 and an optional laser with more power.

I was referring to more of a consumer product:

There are a number of things like this on the market.

That one apparently isn't available yet (available Summer 2018). Can't seem to find a price for it either.

Not sure what the expansion costs for the Fabool unit is; base price is $600 USD

This one is much fancier then the Dremel, and has gotten a lot of press

https://glowforge.com

But not expandable like the Fabtool. That's what make the Fabtool neat.

Nice! It does say "20 by ∞ (Glowforge Pro) ... with a pass-through slot for long materials.", but @ $6000 I'm not holding my breath even for Santa.
