Fibre Laser Cutting vs CO2 Laser Cutting - What’s the Difference?

A Side-by-Side Comparison of Laser Cutting Technologies

When choosing a laser cutting machine for your business, the decision often comes down to fibre laser or CO2 laser technology. While both offer high-quality results, they differ in performance, efficiency, material compatibility, and long-term cost.

What is Fibre Laser Cutting?

Fibre laser cutting uses a solid-state laser that is transmitted through a fibre optic cable. The light is generated using a laser diode and then focused onto the material using a lens.

Best suited for:

• Metal cutting (mild steel, stainless steel, aluminium, brass, copper)

• High-speed precision work

• Industrial applications

What is CO2 Laser Cutting?

CO2 laser cutting uses a gas laser where electricity stimulates a gas mixture to produce a laser beam. The beam is reflected by mirrors before being directed onto the cutting surface.

Best suited for:

• Non-metal materials (wood, plastic, acrylic, leather, textiles)

• Sign-making, engraving, and design

• General-purpose fabrication

Key Differences Between Fibre and CO2 Laser Cutters

Feature	Fibre Laser	CO2 Laser
Cutting Materials	Metals	Non-metals (and some metals)
Cutting Speed	Faster (especially on thin metals)	Slower
Maintenance	Lower – fewer moving parts	Higher – mirrors, gas refills
Energy Efficiency	Very high	Moderate
Operating Costs	Lower	Higher
Machine Lifespan	Longer	Shorter
Initial Cost	Higher	Lower

Which Laser Cutting Machine is Right for You?

Choose a fibre laser cutter if:

• You primarily cut metal materials

• Speed, precision, and low maintenance are priorities

• You operate in industrial or high-volume settings

Choose a CO2 laser cutter if:

• You work with non-metallic materials (wood, acrylic, plastic, etc.)

• You’re in signage, engraving, crafts, or design

• You have a smaller budget or need a more versatile entry-level machine
