Laser Processing Comparison: Fiber vs. CO2—Which Technology is Right for You? Let the Results Speak for Themselves!
Understand the technology but not sure how to choose? The results will guide you! When engraving metal and non-metal materials, "fiber laser" and "CO2 laser" are the two most common laser processing technologies. For applications like marking part numbers, identifying logos, or engraving acrylic sheets and glass cups, how do you choose the right processing machine? Let the finished product guide your choice, making it instantly clear:
"Fiber laser" and "CO2 laser" are the two most common laser processing technologies. The main difference lies in their light source wavelengths. Because different materials absorb different wavelengths of energy, the materials that can be processed by these two technologies also differ! We previously summarized the fundamental differences between these two technologies (Click to read: 【Laser Processing Knowledge】How to Choose a Laser Processing Machine? Two Key Points for Quick Understanding!)
．Fiber Laser – Engraving Metals
The engraving speed, power, pulse, and frequency of the marking machine all affect the "color" effect of the finished product. Taking the stainless steel plate in the image below as an example, under the thermal action of the laser, the surface of the stainless steel plate undergoes a thermal effect, producing colored oxides or a colorless transparent oxide film. Therefore, various colors are presented through the interference effect of light. (Click to read: How to Set Parameters for Color Metal Marking?)

In addition to stainless steel plates, materials commonly used for corporate logo marking include various metal items such as aluminum alloy, galvanized steel, pure aluminum, and brass. Depending on the material properties, the results of fiber laser marking vary. Regardless of the metal material, the engraving effect always maintains the object's original smooth and delicate surface, ensuring fast processing speed while maintaining product quality.

CO2 Laser – Engraving Non-Metals
CO2 laser technology is suitable for engraving various "non-metal" materials, including gypsum, wood, fiberboard, tiles, paper, leather, plastic, acrylic, rubber stamps, etc. Besides engraving, it can also cut thicker materials. Since its wavelength can be absorbed by transparent materials, it is often used for engraving on thin films. (Click to read: Wood, Acrylic, Glass, Clear Engraving of 2pt Tiny Text!) In addition, it can also laser cut the aforementioned materials, creating highly detailed patterns. The combination of laser engraving and cutting can create various artistic works.

CO2 laser engravers are commonly used in design and art fields, and are also widely utilized by individual studios, schools, and students. In addition to the flat engraving mentioned above, curved objects such as mugs, plastic Christmas tree ornaments, wooden water bottles, etc., can also achieve the desired effect with a rotary axis.

Have you found the laser engraving technology that suits you? Fiber laser markers and CO2 laser engravers are not inherently better or worse due to their different technologies. Both can achieve the most exquisite processing effects on their respective suitable materials. By utilizing both technologies, and even combining them, you can unleash your creativity and generate greater business benefits from an artistic perspective. 3DMart offers more than just 3D printing.
