Difference between UV laser and fiber laser engraving machine

These two laser machines can both engrave a large number of materials such as metals, plastics, leather and other materials. However, what are the main differences and why is one much more expensive than the other? In this article we will explain the difference between these two technologies and their primary use.

Both machines look the same

These machines may look basically the same and from the outside completely identical, but the technology that these machines use inside is different! The fiber laser uses a different laser energy source than the UV laser, in addition the UV laser must be cooled with water while the fiber laser only needs air cooling.

These machines are designed for engraving different types of material

The fiber laser engraving machine has as its primary application the engraving, marking and (thin cutting) of metals and is mainly used in the metal industry. The UV laser is primarily designed to easily engrave plastics and glass. In addition, this machine can also mark other materials such as metals and paper. View the list of materials that these machines can engrave and mark.



Typical UV laser applications

Marking: some metals

Marking and engraving of all plastics

Marking all types of glass

Marking and engraving of some types of stone

Marking paper

Marking and engraving of leather

Marking of fruit

Marking wood

Marking of ceramics

Marking of clothing and textiles

Typical fiber laser applications

Marking and engraving of all metals

Marking and engraving of some plastics

Marking a number of stone types

Marking a number of leathers

Marking a number of papers

Marking a number of textile types

As you can see, more materials can be engraved with a UV laser than with the fiber laser. The UV laser can mark on a large number of different materials, but lacks the power and the ability to engrave (and / or cut) metals. This is the great advantage of the fiber laser over the UV laser: the ability to mark, engrave (and cut) all metals.

What are the benefits of UV laser machines?

The most important advantage of UV laser technology is the multifunctional usability for marking and engraving of a large number of materials including non-metals and in particular plastics. This technology is suitable for rotary engraving or to integrate and automate in a production line, also in combination with vision systems. UV lasers are perfectly suited to mark plastics such as ABS and PLA with high resolution and extremely durable, certainly in comparison with tampon printing techniques. Ideal for placing product, certification information and unique serial numbers and bar codes.

What is the disadvantage of UV laser machines?

One of the disadvantages of UV laser technology is the weak engraving in metals, if you are looking for a machine that can engrave metals, then the fiber laser engraving machine is a better option.

What is the advantage of fiber laser engraving machines?

The most important advantage of the fiber laser engraving machine is its capacity to engrave and mark all metals at high speed. The fiber laser can also mark different non-metals, but the result on these materials will often be less qualitative than with a UV laser machine.

What is the disadvantage of fiber laser engraving machines?

The big disadvantage of this machine is that metals can be engraved, but most other materials are not or with lesser quality. Materials that can be processed with good results with a UV laser such as wood, glass (in general all transparent objects), all plastics, paper. The higher power makes it practically impossible to neatly engrave plastics such as ABS and PLA, making edges ragged and you feel the engraving when you rub it. This will not happen with a UV laser.
