What’s the difference between UV laser and Fiber laser marking machine? (lisa)

Fiber Laser marking machine and UV Laser Marking machines. The both machines can engrave a lot of materials, plastics, leather, metals, and others. However, whats the main difference and why one is much more expensive than the other?Here we are going to explain whats the difference between these two technologies and what are their primary use. because

1.Laser generator

UV laser marking machine:

It is with 355nm UV laser.

The machine uses third-order cavity frequency multiplication technology compared with infrared laser(fiber laser,Co2 laser). The 355UV light focusing spot is extremely small, which can greatly reduce the mechanical deformation of the material and Small processing thermal effect. since

Fiber laser marking machine:

The wavelength is 1064nm.

With regard to the wavelength of laser light, the shorter the wavelength, the smaller and higher accuracy the laser spot, and the smaller the heat affected zone formed during processing, the more exquisite the processing effect.


2.The basic working principle of laser processing materials:

Infrared laser (Co2 laser and fiber laser marking machine)

The substance of the material surface is heated and vaporized (evaporated) by laser, this way, the material removed, this approach is often referred to “thermal processing”.


UV laser marking machine

High-energy UV photons directly destroy the molecular on the surface of the material, this way, molecules removed, the process does not produce high heat and it is called “cold processing

3.The machine structure

The main structure of this machine by outlook may look similar, but the technology that these machines use inside is different.

The fiber laser uses a different power supplier than the UV laser,

Other of the difference is that the UV laser needs to be refrigerated by a water chiller,while the Fiber laser is refrigerated only by air.


These machines are design for different material engraving solutions

The fiber laser engraving machine has as a primary use engrave and offer solutions to the metal marking industries, this machine it can mark, engrave (see the difference between engraving and mark) and carve over all the metal materials. but

Moreover, the UV laser is designe to be a practical solution for marking plastics and glass . The UV laser machine it can engrave a vast number of materials, from metals to paper. Check the list of materials that this machines can engrave and mark.
