Laser marking is the best and fastest way to make marks on things. It doesn’t even touch the object. Unlike other methods, laser marking is much more reliable and safe. This “UV laser VS Fiber Laser Marking Machine” guides you in learning more about UV and fiber lasers.
This article mainly discusses the similarities and differences between each method. If you know how they differ, you can choose the correct method for your project.
UV Laser VS Fiber Laser Marking Machine: Similarities
All laser marking machines serve the same purpose: marking things. UV and fiber laser marking machines are both prevalent in a wide range of applications. People use them to mark metals, plastics, wood, and more. Although they have some differences, they share some similar properties.
UV Laser vs Fiber Laser Marking Machine: Precision and Accuracy
Both UV and fiber laser marking machines are highly accurate. They both use highly focused laser beams to create great-quality markings on materials. The final result is always fine and detailed.
UV and fiber laser marking machines can be used multiple times. They prove high repeatability in all-purpose marking jobs. In general, both laser devices work on most solid materials. Fiber lasers may have some difficulties dealing with organic materials.
Both fiber and UV laser marking machines are non-contact processes. Therefore, marking with these machines ensures the integrity of the material surface. This means that both laser sources produce less HAZ area near markings.
Fiber Laser VS UV Laser Marking Machine: Material Compatibility
The laser wavelength typically determines which material you can work with which laser. Fiber and UV laser marking machines are both versatile in this case. They both produce permanent marks on various materials. However, there are usually some differences between them.
As you know, UV laser produces shorter wavelengths. Therefore, they usually make less heat. Because of this, people prefer this machine for heat-sensitive products. Working with plastics or glass needs a very careful step. UV laser markers, in this case, help a lot.
Fiber laser, on the other hand, produces a higher laser wavelength than UV. Their laser wavelength is highly suitable for working with metals. Therefore, fiber laser markers are often used in the metal industry.
UV Laser vs Fiber Laser Marking Machine: Heat Generation
Regarding heat generation, the laser wavelength matters a lot here. As you know, UV lasers usually operate at 150 to 350 nm wavelengths. UV laser marking is called the cold marking process compared to other laser marking methods. This means they produce less heat and reduce the risk of your material damage. Therefore, UV laser marking machines are highly suitable for heat-sensitive materials.
Fiber laser marking tools, on the other hand, make longer wavelengths. Because of this, they make more heat during writing than UV lasers. Because of this, heat-affected zones (HAZ) could form on objects, especially metals. Fiber laser markers work best on hard materials.
Fiber Laser VS UV Laser Marking Machine: Marking Speed
Once again, the laser wavelength also matters when considering the marking speed. Fiber laser marking uses longer wavelengths. It offers faster marking speeds on metals and plastics. It usually produces high-intensity light that can quickly engrave or mark surfaces. One single pass is generally enough to create high-contrast markings.
On the other hand, UV lasers have a shorter wavelength. They produce finer markings, but the process is slower than fiber laser markers. You may need multiple passes to get the high-contrast results.
UV Laser vs Fiber Laser Marking Machine: Cost
UV laser markers are generally more expensive than fiber lasers. As you know, UV lasers are more greener than fiber lasers. They produce less heat and are considered cold laser markers. Engineers must use complex setups to achieve such properties, which adds extra costs.
On the other hand, fiber lasers are more cost-effective. They use longer wavelengths and are great for marking metals and plastic. Fiber lasers are widely used in industrial settings and many DIY projects, making them an excellent choice for beginners.
Summary
Fiber and UV laser markers both have some good points in common. They are accurate, can be used on many materials, and are environmentally suitable. They are also easy to use and don’t need as much maintenance. But they are also different in some ways. The most crucial difference between them is their wavelength. UV lasers make shorter wavelengths, while fiber lasers make longer wavelengths.
UV lasers don’t produce much heat but take time to finish. In contrast, fiber lasers are powerful, quick, and cheap but form HAZ on metals (if not handled carefully). Each has pros and cons, meaning they can be used for different things.
