What is a CO2 Laser Cutter?

CO2 laser cutters use a focused beam of CO2 gas laser to cut through materials. They typically have 40-100 watts of power. The CO2 laser is well-absorbed by most plastics and organics, making it ideal for cutting, engraving, and etching these materials. Metals can also be cut with an assist from oxygen.

How Does a CO2 Laser Cutter Work?

A CO2 laser tube generates an infrared CO2 laser beam. This beam is focused through a series of mirrors or lenses onto the workpiece. The material absorbs the laser energy, which heats up a small area and melts or burns through the material. A computer controls the movement of the laser head while the laser is active to cut the desired pattern.

CO2 Laser Cutter Capabilities:

  • Cut through wood, acrylic, leather, fabrics, cardboard, paper, cork, and some foams and rubbers up to 1/4" thick

  • Engrave designs, logos, and text into the surface of the above materials

  • Etch delicate patterns and artwork into wood, leather, and glass

  • Cut metal when assisted by a constant stream of oxygen

  • Handle small jobs in plastics, acrylics, and organic materials

What to Look for in a CO2 Laser Cutter:

  • Laser Power - 40W is sufficient for light materials. Go with 60-80W to cut thicker and denser materials.

  • Work Area Size - Consider the size of materials you want to cut. 12"x20" to 24"x36" is typical.

  • Linear Motion System - High precision ball bearing rails offer smooth and accurate cutting.

  • Precision - Look for position precision under 0.005" for clean cuts.

  • Safety Features - Must have emergency stop buttons, lid locks, and fire prevention.

  • Exhaust System - For fume extraction. Many have a blower, but some require external exhaust.

  • Software - User-friendly software with design, editing, and layout tools.
