A fiber laser marking machine can mark wood, but its effectiveness and suitability are limited, so it needs to be evaluated based on the specific situation. Here are some key points:

Advantages

1. High Precision: Fiber laser marking machines are great for fine patterns and text engraving.
2. Fast Speed: They can complete simple marking tasks quickly.

Limitations

1. Wavelength Mismatch: The wavelength of a fiber laser (typically 1064nm) is better suited for metals and some plastics. It has a lower absorption rate on wood, so the engraving effect may not be very noticeable.
2. Insufficient Power: Deeper engraving on wood requires higher power, whereas fiber lasers are generally used for shallow surface marking.
3. Risk of Burning: Due to the short exposure time, the wood surface may burn or carbonize, creating a smoky effect.

Solutions

If you want to achieve a good result on wood, consider:

• Lowering the Power: To avoid burning the wood surface.
• Choosing Suitable Materials: Opt for light-colored, evenly-textured woods (like maple or birch), as the engraving effect will be more noticeable.
• Using Other Laser Types:
• CO2 Laser Marking Machines: Better suited for wood, providing clearer results.
• UV Laser Marking Machines: Suitable for higher-precision wood processing.

If your primary material is wood, it is recommended to use a CO2 laser machine for better efficiency and results.
