Laser cutters are certainly a Hackerspace staple for cutting fabrics in some circles. But for the few fabrics derived from non-woven plastics, why not try fusing them together? That’s exactly what [Dries] did, and with some calibration, the result is a speedy means of seaming together two fabrics–no needles necessary!

The materials used here are non-woven goods often used in disposable PPE like face masks, disposable aprons, and shoe coverings. The common tool used to fuse non-woven fabrics at the seams is an ultrasonic welder. This is not as common in the hackerspace tool room, but laser cutters may be a suitable stand-in.

Getting the machine into a production mode of simply cranking out clothes took some work. Through numerous sample runs, [Dries] found that defocusing the laser to a spot size of 1.5mm at low power settings makes for a perfect threadless seam. The resulting test pockets are quite capable of taking a bit of hand abuse before tearing. Best of all, the fused fabrics can simply be cut out with another pass of the laser cutter. For fixtures, [Dries] started with small tests by stretching the two fabrics tightly over each other but suggests fixtures that can be pressed for larger patterns.

It’s great to see laser-cutters doubled-up as both the “glue” and “scissors” in a textile project. Once we get a handle on lasering our own set of scrubs, why not add some inflatables into the mix?
