What is their similarity?

1.The main structure of them looks similar.

2.Both of them can engrave lots of materials, such as plastic, leather, paper, wood, ceramics, metal, and others.

What is their difference?

1.UV laser marking machine is much expensive than fiber laser marking machine.

2.UV laser needs to be refrigerated by a water chiller, while the Fiber laser is refrigerated only by air.

3.UV has less power of engraving and carving over metal materials, it is there when the fiber laser machine can have a significant advantage over the UV laser at the time of mark, engrave and carve metal materials.

4.In simple words, the main advantage of the fiber laser engraving machine is its capacity of engraving, mark and carve at high speed and the metal materials. The fiber laser also can mark different non-metal materials but the result of the engraving on these materials is not going to be as well done like with a UV laser machine. However, this is extra points for the fiber laser machines, the capacity to work perfectly over metals and to work over some non-metal materials.

5.The disadvantage of this machine it comes when we want to engrave non-metal materials. We can't engrave or mark several materials that the UV it can engrave, like wood, glass, all the plastics, paper, or in general transparent objects. For example, this machine can engrave ABS and PLA both very common plastics in different products. The engraving over these plastic materials has 5 to 10% of melting when we use the fiber laser machine, this means that when you touch with your finger its possible that you can feel the surface of the engraving just by touch. It is something that will never happen with the UV laser machine engraving.

How to choose these 2 kind of laser machines?

UV laser marking machine can engrave more materials than the fiber laser. The UV laser it can mark over different materials, but it has less power of engraving and carving over metal materials, it is there when the fiber laser machine it can have a significant advantage over the UV laser at the time of mark, engrave and carve metal materials. So if the buyers want to mark metal materials, please choose fiber laser marking machine. If for non-metal materials and glass, UV laser marking machine is better.
