Fiber Laser vs. CO2 Laser Cutting: Key Differences Explained

51


Laser Wavelength

· Fiber Lasers: Operate at 1.06 micrometers, ideal for cutting metals like aluminum, copper, and brass. The shorter wavelength allows for precise and efficient metal cutting.

· CO2 Lasers: Operate at 10.6 micrometers, better suited for non-metals like wood, acrylic, and plastics. The longer wavelength is less effective on metals but highly efficient for organic and synthetic materials.

Material Compatibility

· Fiber Lasers: Best for metals (stainless steel, aluminum, copper, brass), ideal for high-precision metal fabrication in industries like automotive and aerospace.

· CO2 Lasers: Best for non-metals (wood, acrylic, glass, textiles, plastics), preferred in industries such as signage, woodworking, and packaging.

Cutting Speeds  

· Fiber Lasers: Faster on metals, especially thinner materials, making them ideal for high-volume production.

· CO2 Lasers: Slower on metals but efficient for cutting non-metals with clean, smooth results.

Efficiency in Cutting Thicknesses of Materials

· Fiber Lasers: Highly efficient for thin to medium-thick metals, though slightly less so for very thick metals.

· CO2 Lasers: Versatile for thicker non-metal materials, but less efficient for very thick metals.

 Power Consumption

· Fiber Lasers: Lower power consumption, minimal maintenance, making them more cost-effective in the long run.

· CO2 Lasers: Higher power consumption, frequent maintenance (gas tube replacement, optics alignment), leading to higher long-term costs.

Long-Term Cost-Effectiveness 

· Fiber Lasers: More cost-effective for high-volume metal cutting due to lower maintenance and power costs.

· CO2 Lasers: Cost-effective for non-metal applications, though higher maintenance and power consumption increase long-term costs.
