【Laser Processing Comparison】Fiber vs. CO2: Which Technology is Right for You? See the Results to Know!
Understand the technology but not sure how to choose? You'll know once you see the results! When engraving metal or non-metal materials, "fiber laser" and "CO2 laser" are the two most common laser processing technologies. For applications such as marking part numbers, identifying logos, and engraving acrylic sheets or glass cups, how do you choose the right processing machine? You can easily choose the right machine by looking at the finished products:
"Fiber laser" and "CO2 laser" are the two most common laser processing technologies. The main difference lies in the wavelength of the light source. Because different materials absorb different energy wavelengths, the materials that can be processed by these two technologies also differ! We previously summarized the differences in the principles of these two technologies (Click to see: [Laser Processing Knowledge] How to choose laser processing? Two key points for a quick understanding!)
．Fiber Laser – Engraving Metal
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 action of laser heat, the surface of the stainless steel plate undergoes a thermal effect, forming colored oxides or a colorless transparent oxide film on the surface. Therefore, various colors are presented due to the interference effect of light. (Click to see: Color metal marking, how to set parameters?)

In addition to stainless steel plates, common materials used for corporate identity marking include aluminum alloy, galvanized steel, pure aluminum, brass, and other metal items. Due to the different characteristics of materials, the results of fiber laser marking vary. However, regardless of the metal material, the engraving effect always maintains the original smooth and delicate surface of the object, offering fast processing speed while ensuring product quality.

CO2 Laser – Engraving Non-Metals
CO2 laser technology is suitable for engraving various "non-metal" materials, including plaster, 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 marking films. (Click to see: Clear engraving of ultra-small 2pt fonts on wood, acrylic, and glass!) In addition, it can also laser cut the materials mentioned above, creating highly detailed patterns. Laser engraving combined with cutting can create various artworks.

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

Have you found the laser engraving technology that suits you? Fiber laser marking machines and CO2 laser engraving machines have no inherent good or bad because of their different technologies. Both can achieve the most exquisite processing results on materials they are suitable for. By skillfully utilizing both technologies or even combining them, you can freely unleash your creativity and generate greater business benefits from an artistic perspective. 3DMart offers more than just 3D printing; contact us now to learn more about laser engraving applications.
