For example, running at maximum power at the 4kW, fiber laser cutter, and its chiller will consume about 18 kW of electricity. In contrast, the CO2 laser cutter and its chiller will run at the expense of 70 kW power consumption.

Operating Cost:

If we want to know the difference between fiber and CO2 laser cutting mahcine, we should know that the fiber laser cutter is half than that of a CO2 laser cutter in terms of the operating cost. The reason is that the former features lower power consumption and higher electrical efficiency.

Edge Quality:

As the thickness of processed material enhances, the cutting results will vary along with. There is a concerned difference between fiber and CO2 laser cutting machine. The CO2 lasers can show better edge cutting effects on the thick stainless steel and aluminum workpieces. Yet, the fiber lasers can’t attain the same effects. One of the influencing factors is the consumption of the higher auxiliary gas. The fiber lasers will use over 30 percent to assist gas. wondering the reason for such a situation, the smaller spot size might be the best answer.

Cutting Speed:

To begin with, both the fiber laser cutter and CO2 laser cutter can process many same materials. However, the difference between fiber and CO2 laser cutting machine is that the former can produce better cutting results when handling some metals, i.e. copper, brass, and aluminum. Secondly, both two laser cutters can mark on the aluminum. But, the CO2 laser cutter will take more time to pierce a hole than the fiber laser cutter. Finally, when processing the stainless steel with nitrogen, the fiber laser cutter is much evidently faster.

Time-Saving: The fiber laser machine can be equipped with two interchangeable tables. In such platforms, all materials are conveyed automatically without labor efforts. In this way, there will be a great decline in the tedious and mechanical work and save a lot of time.

Speed: When processing the thin materials, the fiber laser cutter machine is much faster than the CO2 laser cutter. The high-speed attributes to the easy absorption performance of the laser when cutting with Nitrogen (fusion cutting).


Thick Material Finish: The fiber laser cutter is relatively less effective than the CO2 laser cutter in handling the thicker materials. CO2 laser cutter is more penetrating in the handling of finishes, especially making from stainless steel and aluminum.

Laking Flexibility: In comparison with the CO2 laser cutter, the fiber laser cutter is evidently weaker in the handling of a wider range of materials, in particular nonmetals. As the booming of the fiber cutting technology, the fiber laser cutting machine indeed can cut many metals, i.e. brass and copper. Yet, the fiber laser cutter still confronts many limits in practical utilization, especially in processing nonmetal materials.

CO2 Laser Cutter


Wide Applications: From the perspective of macroscope, the COS laser cutting machine finds wide applications in the processing of various materials, i.e. wood, glass, textiles, plastics, foils & films, leather, stone. Yet, speaking exactly, the CO2 laser cutter could generate better cutting effects on the plate stainless and aluminum workpieces in the practical application.

Flexibility: CO2 laser cutter can be extremely flexible in a wide range of laser application projects, covering non-metals.

Long-established Reputation: The CO2 laser cutting technology has appeared for around 30 years. And correspondingly, the CO2 laser cutter also appears in the market up to over 30 years. With the test of time, the CO2 laser cutter will be a good assurance for a user.


Higher Operating Costs: The CO2 laser cutter equips with the CO2 Resonator, Blower, chiller, and other high power-consuming components. Therefore, its power consumption registers 70% higher than other cutting machines.

Maintenance: All of the above-mentioned components of the beam path delivery system require maintenance which can not only be disruptive to manufacturing but also very costly.

Highly Sensitive: The CO2 laser cutter is very sensitive. If you remove slightly the reflecting mirror that focuses on the laser, there is a need to realign. Moreover, this work must be conducted by an expert. Besides, the CO2 laser cutter cannot be compatible with reflective metals. The beam emitted from such metals would cause irreparable damage to the machine.

Ⅳ: Working Way: Fiber Laser VS CO2 Laser

How Fiber Laser Cutting Machine Works?

The fiber laser cutting machine boasts a row of diodes. These diodes could emit a beam of light, which then is transmitted via optic cables and gets amplified there. There are rare earth elements in the cables, which can amplify the light. Finally, the reflecting mirror focuses the light to form a beam of laser for cutting.

How CO2 Laser Cutter Works?

At the beginning of the cutting process, the CO2 laser cutter forms a light beam. And then, such a beam of light will be directed toward the outlet via the reflecting mirror. On its way, the focusing lens serves as a resonator that forms the light energy in the beam. After the forming of the beam, the nozzle of the cutting head leads the beam of light onto the working piece. The resulted beam of light can melt the various metals and keep the cut edge clean simultaneously.

Ⅴ: Future Trends:

Continuing with the above contents, let us have an outlook for future development. Although the majority of the industries are still employing CO2 lasers, fiber laser cutting machine began to boom in the market. Now, there is a growing number of businesses that turn to purchase the fiber laser cutting machine.

The fiber lasers have fewer mobile components and much less adjustments to do. That means much less maintenance costs than the CO2 laser cutter.

But, that does not mean that the CO2 lasers are totally outmoded. When processing thicker materials of 10mm, the CO2 lasers will produce more better edge quality.

On the whole, the fiber lasers see a promising future as a latter comer. One of the determining element is that it is friendly to the atmosphere.
