It comes down to wavelength. Fiber lasers (1064nm) are absorbed efficiently by metals, making them perfect for cutting and marking stainless steel, aluminum, and brass. CO2 lasers (10.6µm) are better absorbed by organic materials like wood, acrylic, leather, and glass, providing superior edge quality for non-metallic projects.

For high-contrast marking on plastics or sensitive electronic components, UV lasers are often the best choice because they use "cold processing" to avoid heat damage. However, for robust industrial plastics or metals, a standard Fiber marking machine offers the highest speed and durability. You can also explore our laser marking options for different production needs.

Power dictates thickness and speed. For example, a 1kW fiber laser can cut thin sheets efficiently, but 3kW+ is needed for thicker carbon steel or high-speed industrial production. Limtek engineers analyze your material gauge and daily output targets to recommend a configuration that balances performance with ROI. If you need a sheet fiber laser cutting machine, power selection becomes especially important.

To ensure a smooth setup, you will need a stable, level floor, a dedicated power supply matching the machine’s voltage, and proper exhaust ventilation. For fiber cutting, you must also prepare high-purity assist gases (Oxygen, Nitrogen, or Compressed Air) and adequate floor clearance as per Limtek’s site-prep checklist.

Yes. Limtek provides a professional sample testing service. Send us your materials, and we will perform test cuts or marks using different machine configurations. We then provide you with high-definition video of the process and return the physical samples so you can verify the precision and finish firsthand.
