Why is Uv 3d laser machine more expensive than fiber laser marking machine?

Why is the UV laser marking machine more expensive than the fiber laser marking machine? In some special materials, the UV laser marking machine is better than the optical fiber, such as ABS, PP, UV, etc. The main reason is that UV waves are different from fiber optic waves. Ultraviolet light has a wavelength of 355 mm, which is a short wave. One of the characteristics of short wavelengths is that they do not have much thermal effect on materials.

The galvanometer and lens of the UV laser marking machine in Dongguan are different in thickness and material from the coating of the fiber laser marking machine, so they cannot be used universally. The galvanometer and lens of the UV laser marking machine are also more expensive. The price difference between the mirror and the lens is not much, and the main price difference is in the ultraviolet laser and the fiber laser.

On the other hand, UV laser marking machines have relatively higher requirements on the environment, especially water-cooled lasers, which need to be kept at a constant temperature, so there are higher requirements for accessories. Due to the extremely small focusing spot and the small processing heat-affected zone, the ultraviolet laser can perform ultra-fine marking and special material marking. It is the preferred product for customers who have higher requirements on the marking effect.

In addition to copper materials, UV lasers are suitable for a wider range of materials. Not only the beam quality is good, the focusing spot is smaller, and ultra-fine marking can be realized; the scope of application is wider; the heat-affected area is extremely small, and there will be no thermal effect and no material burning problem.

The overall combination makes the price of the UV laser marking machine relatively expensive, which is mainly reflected in the high cost of the UV laser and the large labor cost in the later stage.
