Which is better? Fiber laser marking machine and UV laser marking machine?

In addition to CO2 laser marking machine, UV laser marking machine and fiber laser marking machine are the major types of laser marking machine in the market. So which is better? Fiber laser marking machine or the UV laser marking machine? Well, it’s quite complicated to decide, as they both have their pros and cons. But first, let’s look at the differences of these two.

1.Laser source is different
Fiber laser marking machine adopts fiber laser as the laser source while UV laser marking machine adopts UV laser as the laser source, as their names suggest.

2.Working principle is different. 
Fiber laser marking machine posts high energy laser light on the material surface so that the surface will evaporate and then the inside of the material will appear.

But for UV laser marking machine, it uses short-wavelength laser light to break the molecular chain of the material so that the programmed characters or patterns will appear. 

3. Application is different
Fiber laser marking machine is suitable for marking metal. Because of amount of heat generated, it is not suitable for high precision marking. 

On the contrary, UV laser marking machine, because of its “cold processing” feature, it is quite ideal for high precision marking, such as PCB, computer components, industrial bearings, watches, communication products, automobile parts, jewelry and plastics and so on. 

So what are the advantages for fiber laser marking machine and UV laser marking machine respectively? 

1.Advantages of fiber laser marking machine

1.1 High quality laser beam
This high quality laser beam ensures the laser marking is permanent and won’t fade out because of environment changes. The markings are quite delicate and beautiful

1.2 Long service life
The service life of fiber laser marking machine could reach 100,000 hours

1.3 Environmental friendliness
Fiber laser marking machine won’t produce any pollution or noise.

1.4 Low maintenance

2.Advantage of UV laser marking machine

2.1 Ability to perform ultra-precise marking and marking on special materials
This results from its ultra-small focus and tiny heat-affecting zone. 

2.2 The feature of “cold processing”
As mentioned before, UV laser marking machine uses laser light to break the molecular chain of the material, so it won’t produce heat during the operation. Therefore, the damage to the material is also zero.

2.3 Low energy consumption

From the above comparison, you can decide which is better for your own, as what is best for you is what most suits you. But there is one thing that needs to be mentioned, since UV laser marking machine is often used to perform precision marking, the precision needs to be maintained by an air cooled recirculating chiller. S&A Teyu CWUL-05 UV laser cooling chiller is specifically designed for cooling UV laser marking machine from 3W-5W. This air cooled recirculating chiller is characterized by ±0.2℃ temperature stability and 370W cooling power. With 2-year warranty, users can rest assured using this UV laser cooling chiller.

UV laser marking machine has fantastic performance in plastic marking

Unlike traditional marking techniques, UV laser marking machine works precisely and efficiently with the ability to perform marking of any shapes or characters or patterns as long as the computer can program them. Besides, Ultraviolet laser marking machine is friendly to the environment and has low maintenance. Among all the laser marking machines, people find that UV laser marking machine has more fantastic performance in plastic marking.

UV laser is characterized by short wavelength whose output power stimulates the chemical reaction of the materials. Meanwhile, UV laser can avoid excessive heat output. When processing some sensitive materials like plastic which contains flame retardant, UV laser can realize high definition marking and get the best surface quality and fastest processing speed. While for using infrared laser or green laser, expensive laser sensitive additives need to be added. Bur UV laser requires nothing. 


Generally speaking, laser marking on the plastic switch refers to changing the color under the surface of the materials. When using UV laser, blackening marking can be achieved by selectively 
carbonizing the lower layer of the plastic. The heat energy input is limited to a very small designated area, so that the marking content and the background material can be separated clearly. In addition to having the outstanding features of normal laser marking machine, UV laser marking machine is faster with the speed up to 3000 characters per second. 

UV laser is the core component of UV laser marking machine and it needs to be cooled down properly to maintain the outstanding marking performance. Therefore, ultraviolet laser portable water chiller is required. S&A Teyu ultraviolet laser portable water chiller CWUL-05 is specifically designed for 3W-5W UV laser. It features ±0.2℃ temperature stability and is designed with an intelligent temperature controller which offers two temperature control modes - constant temperature control mode & intelligent control mode. Under intelligent control  mode, water temperature will adjust itself automatically based on the ambient temperature, which is quite convenient.

Why UV laser marking machine is so different from fiber laser marking machine in price?

 Laser marking machine features delicate printing effect, clear and long lasting marking and is widely used in different industries. But many users find that there is a huge difference in the price of fiber laser marking machine and UV laser marking machine. So is the application.

Although they are both laser marking machine, fiber laser marking machine and UV laser marking machine adopt different laser sources and the laser powers are quite different. For fiber laser marking machine, it adopts 20W,30W,50W or higher power fiber laser. For UV laser marking machine, it adopts 3W,5W,10W UV laser. Therefore, the main reason for the big price difference of these two types of laser marking machines is that they have different configurations and working principles. 

There are 3 levels in the different types of laser marking machines. The low-end laser marking machine is CO2 laser marking machine. The mid-end laser marking machine is fiber laser marking machine and the high-end laser marking machine is the UV laser marking machine. The reason why UV laser marking machine is high-end is that it has the widest application and has the marking effect that other types of laser marking machines can not achieve. Therefore, UV laser marking machine generally work on high-end products, like i-PHONE and iPAD and other consumer electronics. However, as high-end equipment, UV laser marking machine adopts UV laser as the laser source and UV laser is more expensive than the CO2 laser and the fiber laser, but it has the advantage that other two types of laser sources don’t have. And that advantage is to restrict thermal stress. That is because UV laser can operate under low power. Through a technique called “cold ablation”, UV laser can produce small heat affecting zone, which makes it ideal for making PCB. 

The small heat affecting zone of UV laser marking machine enables it to reduce the charring to the smallest extend. And high power laser sources also have this kind of negative effect. What’s more, UV laser has shorter wavelength than many visible lights, so it can not seen with our own eyes, which makes it less harmful to the human body. 

UV laser has very high absorption rate to resin, copper, and glass. This feature makes UV laser marking machine become the most ideal processing equipment for PCB, FPC, chip and other high-end complicated applications. Therefore, UV laser marking machine is expensive for a reason. 

As mentioned before, UV laser marking machine often adopts 3W, 5W, 10W UV laser source. Since UV laser source is of high price, its service life needs to be well maintained. One of the most common ways is to add a UV laser small chiller unit. S&A Teyu offers CWUP-10 UV laser chiller designed to cool up to 10W UV laser. This small chiller unit features ±0.1℃ temperature stability and supports Modbus-485 communication protocol.

What are the materials that UV laser can perform quality marking on?

UV laser features short wavelength, short pulse width, high speed and high peak value. It has become one of the most trending industrial lasers in the current laser market. As UV laser technology develops, its application becomes wider and wider. Nowadays, the commonly seen materials that UV laser can perform quality marking on include plastic, glass, ceramics and metals.

UV laser marking on 3C product plastic

The advent of 3C products is the result of fast development of the electronics industry. To leave a permanent marking on the plastic surface of the electronics, many enterprises introduced the UV laser marking machine. When the UV laser marking machine is working, the working temperature is pretty low with fast speed and enables remote control via the computer to achieve high precision marking. It won’t cause distortion on the plastic materials, for it is non-contact. 

UV laser marking on metal

Many of you may know that most of the parts of PCB consists of precious metals, including gold, silver and copper. For these tiny parts, manufacturers would add their unique marking on the them for better differentiation. Traditional printing technique is hard to achieve precision marking. But with UV laser whose pulse width is only 15nm@30KHz, precision marking can be easily achieved. 

UV laser marking on glass

Glass is a commonly seen in the our daily life. We can often see some beautiful patterns on the glass. They don’t have any color, but they are very beautiful. And those patterns are made by using UV laser marking machine. UV laser marking machine is much faster than manual marking and is more efficient with smoother marking surface. 

UV laser machine can also be applied to FPC/PCB cutting, profile cutting, drilling and mobile phone shell cutting and produce clear characters and patterns. 

Currently, the most mature Ultraviolet laser technology is around 3-10W and is commonly used in industrial level laser micromachining. It can be used to cut wafer, ceramics, thin film and so on. It is believed that UV laser technology will be heading towards higher efficiency, higher power and higher precision.

For cooling UV laser machine, it is better to find a reliable laser cooling solution provider. S&A Teyu is such a supplier. It has 19 years of experience and offers CWUL series UV laser small chiller unit which is applicable to cool 3W-5W Ultraviolet laser.

Will UV laser marking technique replace CO2 laser marking technique?

 CO2 laser was invented in 1964 and could be called as an “ancient” laser technique. In quite a long period of time, CO2 laser was the major player in processing, medical or scientific research fields. However, with the advent of fiber laser, the market share of CO2 laser has become smaller and smaller. For metal cutting, fiber laser replaces most of the CO2 laser, for it can be better absorbed by the metals and is less expensive. In terms of laser marking, CO2 laser used to be the main marking tools. But in the past few years, UV laser marking and fiber laser marking has become more and more popular. UV laser marking in particular "seems to" gradually replace CO2 laser marking, for it has more delicate marking effect, smaller heat-affecting zone and higher precision and is known as “cold processing”. So what are the respective advantages for these two kinds of laser marking techniques?

Advantage of CO2 laser marking
In the 80-90s, CO2 laser became quite mature and became the main tool in the application. Because of high efficiency and good laser beam quality, CO2 laser marking became the common marking method. It is applicable to work on different kinds of non-metals, including wood, glass, textile, plastic, leather, stone,etc and has wide application in food, medicine, electronics, PCB, mobile communication, construction and other industries. CO2 laser is a gas laser and interact with materials using laser energy and leaves a permanent marking on the material surface. This was a huge replacement for inkjet printing, silk printing and other traditional printing techniques at that time. With CO2 laser marking machine, trademark, date, character and delicate design can be marked on the material surface. 

Advantage of UV laser marking
UV laser is a laser with 355nm wavelength. Because of its short wavelength and narrow pulse, it can produce very small focal spot and remain the smallest heat-affecting zone, capable of processing precisely without deformation. UV laser marking is widely used on food package, medicine package, makeup package, PCB laser marking/scribing/drilling, glass laser drilling and so on. 

UV laser V.S. CO2 laser 
In applications which is quite demanding on precision, like glass, chip and PCB, UV laser is no doubt the first option. For PCB processing in particular, UV laser is considered as the best option. From the market performance, UV laser seems to overwhelm CO2 laser, for its sales volume grows at a very rapid speed. That means the demand of precise processing is increasing. 

However, that doesn’t mean CO2 laser is nothing. At least for the time being, the price of CO2 laser in the same power is much cheaper than the UV laser. And in some areas, CO2 laser can do something other kinds of lasers can not do. What’s more, some applications can only use CO2 laser. Plastic processing, for example, can only rely on CO2 laser. 

Although UV laser is becoming more and more common, traditional CO2 laser is also making progress. Therefore, UV laser marking is hard to completely replace CO2 laser marking. But just like most of the laser processing equipment, UV laser marking machine needs the assistance from air cooled water chillers to maintain the processing precision, normal operation and the lifespan. 

S&A Teyu develops and manufactures RMUP, CWUL and CWUP series air cooled water chillers are suitable for cooling 3W-30W UV lasers. RMUP series is rack mount design. CWUL & CWUP series are stand-alone design. They all feature high temperature stability, stable cooling performance, multiple alarm functions and small size, meeting cooling needs of the UV laser. 

What can chiller stability affect laser output of the UV laser? 

As we all know, the higher the temperature stability of the chiller, the less optical loss of the UV laser will be, which reduces the processing cost and extends the lifespan of the UV lasers. What’s more, the stable water pressure of the air cooled chillercan help reduce the pressure from the laser pipeline and avoid the bubble. S&A Teyu air cooled chiller has properly designed pipeline and compact design, which reduces the bubble, stabilizes the laser output, prolong the service life of the laser and helps reduce cost for users. It is commonly used in precision marking, glass marking, micro-machining, wafer cutting, 3D printing, food package marking and so on.

How can laser benefit consumer electronics?

Consumer electronics like smart phones and tablets are changing our life. And laser technique is certainly a game-changing technique in processing the components of these consumer electronics.

Laser cutting phone camera cover

The current smart phone industry increasingly depends on the materials that laser can work with, like sapphire. This is the second hardest materials in the world, which makes it the ideal material that protects the phone camera against potential scratching and falling. Using laser technique, sapphire cutting can be very precise and speedy without post-processing and several hundred thousands of work pieces could be finished every day, which is quite efficient. 

Laser cutting and welding thin film circuit

Laser technique can also be used inside the consumer electronics. How to arrange the components on space of several cubic millimeter used to be a challenge. Then manufacturers come up with a solution - By arranging flexibly the thin film circuit made by polyimide to do the matching in limited space. This means these circuits can be cut to different sizes and shapes to connect with each other. With laser technique, this work can be done very easily, for it is suitable for any working condition and doesn’t cause any mechanical pressure to the work piece at all. 

Laser cutting glass display

For the time being, the most expensive component of smart phone is the touch screen. As we know, a touch display consists of two pieces of glass and each piece is about 300 micrometer thick. There are transistors that control the pixel. This new design is used for decreasing the thickness of the glass and increasing the toughness of the glass. With traditional technique, it is even impossible to cut and scribe gently. Etching is workable, but it involves chemical procedure. 

Therefore, laser marking, known as cold processing, is increasingly used in the glass cutting. What’s more, glass cut by laser has smooth edge and no crack, which requires no post-processing. 

Laser marking in the above-mentioned components requires high precision in limited space. So what would be the ideal laser source for this kind of processing? Well, the answer is UV laser. UV laser whose wavelength is 355nm is a kind of cold processing, for it doesn’t have physical contact with the object and has very small heat-affecting zone. To ensure its long-term performance, effective cooling is extremely important.
