Cutting Fabric and Leather with a Laser

A laser cuts fabric without touching it, so nothing drags or stretches the material and intricate shapes come out exact. On synthetic fabric it does something scissors cannot: it melts the cut edge so it will not fray.

The catch is that fabric and leather are where the most dangerous laser mistakes happen. Several common materials give off toxic, corrosive fumes. Check the material before anything else.

Never laser these

• Vinyl and PVC, including most faux leather and “pleather”. Burning PVC releases chlorine compounds that are harmful to breathe and corrode the machine. If you cannot confirm what a faux leather is made of, do not laser it.
• Chrome-tanned leather. Most soft, colored leather in jackets, bags and upholstery is chrome-tanned. Makerspaces that run lasers every day ban it.
• Anything sticky-backed, glued or marked flame-retardant. Adhesives and fire-retardant treatments burn unpredictably and give off fumes you do not want.

Our laser safety and ventilation guide covers fumes and fire in detail. Read it before your first cut.

What cuts well

Material	Edge	Notes
Polyester, fleece, felt (synthetic)	Melted and sealed	The easiest fabrics to laser. Sealed edges do not fray.
Cotton, linen, wool felt (natural)	Slightly browned	Natural fibers do not seal; edges may char and fray a little.
Vegetable-tanned leather	Darkened	The leather to laser. Edges brown, which many makers like.

Thin fabrics need little power. Most of the work is in avoiding scorch, not getting through.

Diode or CO2?

A CO2 laser is the right tool for fabric. It cuts most fabrics and leather cleanly. A diode laser works only on thin synthetics, and slowly. See diode vs CO2 vs fibre lasers for why, and the xTool P2S for a desktop CO2 machine.

Getting clean edges

1. Run a test cut first. Fabric varies even within one type and color. Cut a small square in a corner before the real piece.
2. Start fast and low. Begin with high speed and low to medium power, in one pass. If it does not cut through, add power or a second pass. If edges scorch, raise the speed or lower the power.
3. Keep synthetics moving. On polyester, too slow a speed over-melts the edge into a hard bead.
4. Hold it flat. Wrinkles throw the focus off and leave ragged edges. Use a honeycomb bed with pins or weights so the fabric cannot lift.
5. Go easy on air assist. A strong blast can lift thin fabric mid-cut. Use a light flow.
6. Focus on the fabric surface. A sharp focus gives a narrow, clean cut.
7. Never leave it running. Fabric can catch fire if it overheats. Stay with the machine for every cut.

When a laser is the wrong tool

For quilt pieces in cotton, a laser is slow and the browned edges are a drawback. A rotary cutter and mat or a fabric cutting machine does that job better. Lasers shine on intricate appliqué shapes, synthetic fabrics that fray, and vegetable-tanned leather.
