Linen
Frequently asked questions
Can Linen be laser cut?
Yes: Linen can be laser cut. Adequate extraction/ventilation is required.
Can Linen be CNC machined?
No: Linen is not suitable for CNC milling.
Is Linen food safe?
Yes, Linen is food safe even in its raw state.

Laser processing
Fumes are of vegetable cellulosic nature, similar to cotton. Untreated raw linen is safe, but finishing treatments (starching, synthetic dyes) may introduce volatile residues. Standard extraction recommended.
CO₂: Good CO2 laser cutting but with slightly more irregular edges compared to cotton due to the structure of linen fibers, which are stiffer and bundled. Requires low power (10–20W) at high speed. Engraving produces sharp, natural contrast.
Diode: Acceptable results on dark or natural-colored fabric. On raw or white linen, blue diode lasers may require multiple passes to cut completely.
Fiber: Not applicable.
CNC / milling processing
Not CNC-machinable with conventional bits: the flexible and strong fibers would wrap around the rotating tool, damaging both fabric and machine.
Plotter and thermoforming
Excellent machinability with rotary blade plotter or deep blade specific for fabrics. Sturdier linen (canvas or heavyweight) may require higher pressure compared to lightweight cotton.
Post-processing
Sanding: Not sandable.
Gluing: Bondable with fabric-specific adhesives or heat-bonding films. The open weave of linen ensures good penetration of water-based adhesives such as diluted PVA.
Over time: Biodegradable natural fiber. Linen tends to become softer with successive washes. Resistant to sunlight compared to other natural fibers, but may yellow slightly over time.
Common defects
- More irregular laser-cut edges than cotton due to the bundle fibre structure
- Edge fraying if cut mechanically without a containment stitch
- Significant dimensional shrinkage at the first wash if the fabric has not been pre-washed
Safety
Linen is flammable but less so than cotton thanks to the more compact fiber structure. Monitor laser processing and ensure air assist is active to prevent smoldering embers.
Availability and formats
Commercial formats: fabric by the metre, raw canvases for painting, printable bags and totes
