CO2 laser cutting machine has a wide range of applications in cutting and engraving non-metal materials. Based on different laser power, the material type and thickness that the CO2 laser cutter machine can cut also different. What do you need to know before buying a CO2 laser cutting machine? Do you know how to buy a CO2 laser engraving machine?
This article offers a comprehensive introduction of the CO2 laser cutting machine, including its definition, application, price, and how to choose. I hope this article can solve all your doubts about CO2 laser cutters.
The CO2 laser cutting machine, or CO2 laser cutter is a type of CNC laser machine using CO2 laser technology to cut and engrave materials. As the CO2 laser cutting machine can also engrave, the CO2 laser cutting machine is also called CO2 laser engraving machine or CO2 laser engraver. Besides, some people also call it wood laser cutter or acrylic laser cutter, etc.
The CO2 laser cutting machine uses a focusing lens to focus the CO2 laser beam onto the surface of the material to melt it. At the same time, the coaxial compressed gas blows away the molten material. The laser beam moves along a certain path, forming a slit of a certain shape. Then the cutting process completes.

Fiber laser cutting machine is also one of the most commonly used laser cutter machine. Different from the gas laser tube and optical transmission of the CO2 laser machine, the fiber laser cutting machine uses a fiber laser and a cable to transmit the laser beam. The wavelength of the fiber laser beam is only 1/10 of that generated by a CO2 laser. So compared to the CO2 laser cutting machine, the fiber laser cutting machine can reveal better consistency and reliability, and can process finer patterns.
The principal differences between a CO2 laser cutter and a fiber laser cutter lie in the following aspects.
A CO2 laser engraving machine uses the CO2 laser tube to generate laser beams. The working substance is mainly CO2, and O2, He, Xe, etc. as the auxiliary gas. The CO2 laser beam is reflected and focused to the laser cutter head by reflective and focusing lenses.
A fiber laser cutting machine generates a laser beam through multiple diode pumps. And then the laser beam is transmitted to the laser cutting head through a flexible fiber optic cable.
The beam wavelength of a CO2 laser is 10.64um and is more easily absorbed by non-metal materials. However, the beam wavelength of a fiber laser is 1.064um, which is 10 times shorter. Due to this much smaller focal distance, the intensity of the fiber laser cutter is almost 100 times higher than the CO2 laser cutter with similar power output. So the fiber laser cutting machine is quite suitable for cutting metal materials.
A CO2 laser engraver can cut and engrave metal materials, its efficiency is low. So the CO2 laser machine is mainly for cutting and engraving non-metal materials. For instance, wood, acrylic, paper, leather, fabric, etc.
Fiber laser cutter, also known as metal laser cutting machine, is mainly for metal materials. For example, stainless steel, carbon steel, galvanized steel, copper, aluminum, etc.
A CO2 acrylic laser cutter consumes a lot of gas when they are working. But its photoelectric conversion rate is only 8% to 10%.
A fiber laser cutting machine requires less other consumption during processing, and its photoelectric conversion rate can reach 25%-30%. So the fiber laser cutter is more energy-saving than the CO2 laser cutter.
The CO2 laser tube has a complex structure and the optical lenses are vulnerable and expensive. Replacement of these consumables requires a lot of expenses. So the maintenance cost for a CO2 laser cutting machine is high.
Fiber laser cutting is basically free of maintenance and has fewer vulnerable pars. It is capable of enduring harsh working environments and has a high tolerance for dust, shock, impact, humidity, and temperature. Therefore, the maintenance cost for a fiber laser cutter is low.
The CO2 laser engraving machine has a large beam divergence during processing, which is not suitable for large-size processing. Although the cutting seam is relatively small, the speed is very slow when processing thick plates.
The features of a fiber laser cutting machine include high density and intensive laser beam, high brightness, and high conversion rate. For thin plate processing, the cutting speed of a fiber laser cutting machine is 2-3 times higher than that of a CO2 laser cutter with the same power.
When you plan to buy an acrylic laser cutter, you may wonder about the CO2 laser cutting machine price. Based on different specifications and configurations, the CO2 laser cutting machine price varies from about $3,000 to $20,000. If you want to buy from abroad, you also need to pay additional fees, such as shipping costs, taxes, customs clearance fees, etc.
As I mentioned before, different specifications and configurations lead to different CO2 laser cutting machine price. So you need to communicate with the CO2 laser machine manufacturer to get the specific and detailed price list. Then, what factors can affect the CO2 laser cutting machine price?
The brand influence of a CO2 laser engraver is reflected in the quality, operation and service of the machine. Large-brand CO2 laser machines typically adopt good quality parts and components to ensure a stable and reliable operation.
As the major device to generate laser beams, the CO2 laser tube is the most important core part of a CO2 laser cutting machine. Besides, there are also other major parts and components, such as optical lenses, guide rail, rack, stepper motor, chiller, etc. Large-brand parts and components have excellent quality, stable performance and long service, and corresponding high price.
The thickness of the materials cut by a wood laser cutter varies according to different CO2 laser power. The higher the CO2 laser power, the thicker the CO2 wood laser cutter can cut. For the CO2 laser tube of the same brand, the higher the power, the higher the price.
The CO2 CNC laser cutter usually doesn't come with large-size worktable. The common size of the worktable includes 600*900mm,1300*900mm, 1400*1200mm, and 1300*2500mm. The higher the worktable size, the higher the CO2 laser cutting machine price.
Service, whether before sales or after sales, is also an important factor. All-round services offer customers machine safety and timely maintenance of the CO2 laser engraver machines. Reliable CO2 laser machine manufacturers can provide complete and consistent services, and their CO2 laser machine has high quality and high price accordingly.
Overall, finding the best wood laser cutter for your needs is going to require some deep consideration on many matters. For example, what you will use it for, the materials you plan to use, ease of use you require, and your price range. So before buying a CO2 laser engraver, you need to do the following preparations.
This includes what materials you plan to cut or engrave, dimension and thickness of such materials. It helps you determine the machine size and power of the CO2 laser cutting machine you need. The CO2 laser engraving machine is good at cutting and engraving non-metal materials of thickness within 0-25mm. If you want to engrave or cut any other surface than plain sheets, such as glass, you may need a rotary device.
There are so many CO2 laser machine manufacturers on the market. It is necessary to take time to do some investigations and select a suitable one. Such investigations shall include the professionalism, production capacity, delivery capacity, service level and other aspects of the CNC laser cutter machine manufacturers.
When you get the quotation, you need to pay attention to the specific configuration of the CO2 laser engraver. Don't be tempted by the low price blindly Because it may have some parts of poor quality.
In short, I would not advise making the choice based on the CO2 laser cutting machine price only. Because I believe that you get what you pay for. Low-priced laser machines are likely to use poor-quality parts, resulting in high maintenance costs in later use.
After you have reached an agreement with the manufacturer and prior to paying the advance, remember to sign a purchase contract. Stipulating the rights and obligations of both parties is helpful for safeguarding the rights and interests of both parties.
