Cutting through even rough materials is possible! Yes, with laser cutters, it has become easier. There are different types of laser cutters, but how many are you familiar with?
The history of laser cutters started in 1965, and with time, they have grown in popularity due to their use in various processes. In 2023, the global market size was valued at USD 1,610.4 million and is estimated to reach USD 3,273.3 million by 2032.
These machines use focused beams of light to cut, engrave, and shape a variety of materials with accuracy. Work with metal, acrylic, fabric, or any other material, and laser cutters will transform your ideas into designs within a short time.
But what types of laser cutting machines suit your business the most? We are here to provide you with all the answers you need right here.
What are the Types of Laser Cutters?
With advancements in technology, different types of cutters are in operation. These could be a bit confusing because you might not know which laser cutter cuts which material.
Each type can be used for a variety of applications and uses a different base material to activate the laser. Let’s go a bit deeper to know which is the best for you and how to choose them.
CO2 Laser
CO2 Lasers are one of the types of laser cutters that run electricity through a gas mixture-filled tube, producing light beams. The gases include carbon dioxide, nitrogen, and helium. It can be used on both metal and non-metal surfaces.
These laser cutters can be used on both metal and non-metal surfaces and work best with non-metallic materials. It is through the mirrors that the intensity is achieved, but as the beam journeys towards the lens, traversing multiple cooled mirrors, there’s an inevitable power and quality drop.
The strongest CO2 lasers can produce many Kilowatts of energy for industrial machinery, although they are the only exception to the rule. A common CO2 laser for cutting has a strong range of between 25 and 100 Wattage and a frequency of 10.6 micrometers.
| Pros | Cons |
| The laser beam can be controlled precisely, usually between 0.1 and 0.5 | Can be very expensive to purchase and set up |
| At high speed, complete a large amount of cutting work in a short time | Not suitable to cut all materials and may emit harmful fumes when cut |
| Multi-material cutting capabilities and handles different types of materials | May struggle to cut materials above a certain thickness |
The maintenance of CO2 laser cutters may be slightly demanding, as you need to check the lens and mirror regularly to maintain the quality of the beam. It’s essential to refill the gas for uninterrupted operations. The moving parts should be clean to prevent performance hindrance.
Fiber Laser Cutter
Have you seen a metal keychain engraved with beautiful patterns? Have you wondered how it’s done? If yes, then now you know the answer. The fiber laser cutter uses high-intensity light to cut materials with speed and accuracy.
It’s made of optical fiber, and the laser is amplified through fiberglass diodes, making it very powerful while using less energy. These lasers cut both metallic and non-metallic materials like ceramics, plastic, glass, and carbon-fiber-reinforced polymers. Fiber lasers produce a wavelength in the near-infrared spectrum, usually around 1.06 μm. This absorbs the materials that are being cut, and, as a result, there will not be any reflection.
It’s one of the types of CNC laser cutting machine that has a long operational life of a minimum of 25,000 laser hours and requires no servicing. They have an equal average output as CO2 lasers but can achieve levels that are 100 times greater.
| Pros | Cons |
| Offer faster speeds than other methods and is ideal for high-volume production runs | Consume a low amount of energy and allows cost cutting |
| Create extremely precise and accurate cuts of complex designs | Trapped fumes can cause discomfort and potential machine damage. |
| Consume a low amount of energy and allows cost cutting | Materials like copper, brass, and aluminum are not compatible |
These types of laser cutters need minimal but essential maintenance, like regular cleaning of the cutting head and lens for optimal beam quality. Annual power source inspection needs to be done to maintain better performance. To prevent disruptions, check fiber optic cables for wear
Nd: YAG/Nd: YVO Lasers
The crystal laser cutting processes can be in nd: YAG (neodymium-doped yttrium aluminium garnet) and more commonly used nd: YVO (neodymium-doped yttrium ortho-vanadate, YVO4).
They have a life expectancy of 8,000 to 15,000 hours and offer a wavelength of 1.064 micrometres. With their high cutting power, they are useful for a huge range of applications. These can be used with both metals (coated and non-coated) and non-metals, including plastics. Under certain circumstances, it can even process a few ceramics. They are best used for metals, including the more “reflective” materials: stainless steel, carbon steel, aluminum, brass, and copper.
| Pros | Cons |
| Has the ability to operate continuously throughout the process | Can be very costly to purchase and set up than other machines |
| Cut many forms of metal, including metal with a powder coating | Relying on pump diodes that can be expensive to replace |
| Cuts through relatively thick and tough materials | Can be less serviceable than other types of laser cutters |
Maintaining machinery is essential for longevity and optimal performance, and Nd: YAG / Nd: YVO lasers are no exception. Regularly checking the cooling system helps prevent overheating, ensuring smooth operation. Diodes, which are integral to the laser’s function, should be replaced periodically to avoid interruptions. Additionally, routine recalibration keeps the laser beam precise, preserving the quality of cuts and overall efficiency.
What To Consider When Choosing the Right Types of Laser Cutters?
- Thickness of Material and Thickness
It is important to understand the type and thickness of the material before choosing the right one. For instance, thick materials might require lasers with a higher power range. When you choose by considering the material, it helps get your results without any issue.
- Accuracy and Quality
The types of laser cutting machine you choose can affect the accuracy of your cuts. Choose the one that provides accuracy.
- Production speed requirements
Choose laser cutters with high-speed capabilities so that you can increase your production. They are particularly well-suited for applications demanding rapid sheet metal fabrication.
- Investment budget:
The initial cost can play a significant role in decision-making. For example, diode lasers are generally more affordable compared to CO2 or fiber lasers.
- Maintenance costs
Maintenance needs can differ depending on the type of laser cutters. Fiber lasers are virtually maintenance-free, while CO2 laser cutters may require more frequent maintenance.
