Fiber Laser Marking Machine vs. CO2 Laser Marking Machine vs. UV Laser Marking Machine: Which One is Right for You?

The choice of laser marking machine depends on their wavelengths and how they interact with materials. Fiber laser marking machines excel in metal marking, CO2 laser marking machines offer versatility for various non-metal materials, while UV laser marking machines focus on high-precision applications for heat-sensitive materials.

What are the differences?

Fiber Laser Marking Machine

- Wavelength: 1.064 micrometers (1064 nanometers)
- Interaction with Metals: This wavelength is effectively absorbed by metals (including gold, silver, and brass), making fiber lasers highly efficient for metal marking.
- Heat Affected Zone (HAZ): A small focus diameter and high intensity at the focal point reduce the heat affected zone.
- Efficiency: Faster marking speeds and lower power consumption.

CO2 Laser Marking Machine

- Wavelength: 10.6 micrometers (10,600 nanometers)
- Interaction with Metals: The longer wavelength leads to lower absorption efficiency by metals, potentially resulting in rougher edges.
- Material Versatility: Capable of cutting and engraving various non-metal materials, such as wood, acrylic, and glass, offering wide applicability.

UV Laser Marking Machine

- Wavelength: 355 nanometers
- Interaction with Heat-Sensitive Materials: The short wavelength allows UV lasers to perform high-precision marking on heat-sensitive materials with minimal thermal damage.
- Application Advantages: Ideal for marking plastics, electronic components, and fine artworks, achieving extremely detailed marking effects.
