Is a CO2 Laser Cutter the Right Pick for Wood and Acrylic?

Published · By the Laser Lineup editors

Summary

If most of your work is cutting wood and acrylic, CO2 is where to start looking. Acrylic absorbs the 10.6 µm CO2 wavelength well, so a CO2 machine can cut clear acrylic that a blue diode can't touch. What you give up is metal, and a glass-tube machine asks for cooling-water and mirror upkeep that a diode never needs.

The xTool P2 as an example

xTool's FAQ for the P2 lists clear acrylic cuts up to 20 mm and solid wood up to 18 mm. Plywood stops at 12 mm, because thicker plywood can catch fire.

It won't cut metal. It will engrave anodized aluminum and coated metals, and stainless steel after a spray coating. xTool's do-not-process list includes PVC, leather that contains chromium, and anything with halogens or epoxy resins.

Upkeep on a glass-tube machine

Glass-tube CO2 lasers are water-cooled. OMTech's support guide says to change the water at least once a month, even when it looks clean, and warns that repeated overheating shortens tube life. The mirrors have to stay clean and aligned.

A tube near the end of its life gives signs. OMTech lists a weaker beam, a change in the color of the glow, and materials that used to cut cleanly no longer going through.
