Today, laser systems stand out among industrial marking technologies. CO₂, Fiber and UV lasers are used for permanent marking on different materials. But what are the differences between these laser types and which laser marking system is more suitable for which businesses? In this article, we will examine in detail the technical differences and advantages of CO₂, Fiber and UV lasers and which materials they are suitable for.
1. CO₂ Laser Marking
CO₂ lasers belong to the class of gas lasers and have a wavelength of 10.6 micrometers. They are commonly used on organic materials such as wood, glass, paper, leather and plastics.
Advantages
- High quality marking on organic materials.
- It can work effectively over a large surface area.
- It does not damage the material thanks to its low heat effect.
Disadvantages
- Not suitable for metal surfaces.
- It may be slower than other laser types.
- Maintenance costs are higher.
2. Fiber Laser Marking
Fiber lasers are solid state lasers with a wavelength of 1.06 micrometers. It provides effective marking, especially on metals and hard plastics.
Advantages
- It can make deep and permanent marking on metal surfaces.
- It offers a fast and highly efficient operating performance.
- It offers an economical option thanks to its low energy consumption.
- Long lasting and maintenance free.
Disadvantages
- Ineffective on glass, wood and transparent plastics.
- It can be more expensive than CO₂ and UV lasers.
3. UV Laser Marking
UV lasers have an ultra-short wavelength (355 nm) and work on the principle of “cold marking”. Ideal for plastics, glass and medical applications.
Advantages
- With its low heat effect, it can mark without damaging sensitive surfaces.
- It creates very clear markings on materials such as plastic, glass and silicone.
- It is preferred in electronic and medical sectors that require high precision.
Disadvantages
- More expensive than fiber and CO₂ lasers.
- Not suitable for metal marking.
4. CO₂, Fiber and UV Laser Comparison Table
| Feature | CO₂ Laser | Fiber Laser | UV Laser |
|---|---|---|---|
| Wavelength | 10.6 µm | 1.06 µm | 355 nm |
| Area of Use | Wood, glass, plastic, leather | Metal, hard plastics | Plastic, glass, medical materials |
| Speed | Middle | High | Middle |
| Sensitivity | Middle | High | Very high |
| Maintenance Requirement | High | Low | Middle |
| Cost | Middle | Medium-high | High |
5. Which Laser Marking Technology to Choose?
- For metal Fiber laser
- For plastic and glass: UV laser
- For wood, leather and organic materials: CO₂ laser
The type of material, precision requirement and budget should be taken into account when making a choice.
CO₂, Fiber and UV laser marking systems have different functions and are specially optimized for specific materials. When deciding which laser marking system to choose, the material to be used and the desired marking quality should be taken into account. By choosing the best option for your business, you can increase productivity and optimize costs.
