How deep can a 40w fiber laser engrave?

2023-03-10 09:50:54

A fiber laser is a laser that uses fiber as the gain medium and has a high output power. Due to the many power options available, many people are unsure if the power they choose can engrave or cut a certain material when choosing a laser engraver. The depth that a 40W fiber laser can engrave on a material depends on several factors, including material type, thickness and laser wavelength, engraving depth, etc.

40W laser engraving depth of different materials

  • Wood: The 40W fiber laser can engrave wood to a depth of approximately 0.2-0.3 mm, depending on the type of wood and its thickness and the speed at which you are engraving.
  • Plastic: Plastic is a common material that can be engraved with a 40W fiber laser. The depth of plastic that can be engraved with a 40W fiber laser depends on the type of plastic and its thickness, but is usually between 0.1 and 0.5 mm.
  • Metals: Metals can also be engraved using a 40W fiber laser. The depth of metal that can be engraved with a 40W fiber laser depends on the type of metal, the thickness and the wavelength of the laser, but can typically reach 0.1-0.5 mm.
  • Glass: Glass can be engraved using a 40W fiber laser, but the depth it can be engraved is usually very shallow.

It is important to note that engraving depth can also be affected by laser focus, power density and speed. To achieve the deepest possible engraving, the laser should be tightly focused and the engraving speed should be kept slow to allow the laser to remove more material.

Conclusion

In summary, the depth to which a 40W fiber laser can engrave depends on several factors, including material type, thickness and laser wavelength. The type of material being engraved and its thickness can significantly affect the depth of engraving, but under the right conditions, a 40W fiber laser can produce an engraving depth of 0.2-0.5 mm or deeper.
