Make sure your laser engraver is equipped to handle the specific metal.

2. Prepare the Surface

For the best engraving results, ensure the metal surface is clean and free from any dust or oils. Use a soft cloth and a mild cleaner to remove impurities. This step is essential for achieving consistent and high-quality engravings.

3. Import and Set Up the Design

Using your preferred design software, import your graphic or text. SA Lasers’ SPARK training curriculum guides clients on preparing designs for engraving, including vectorizing and adjusting for optimal clarity.

• Tip: Simple designs with bold lines or clear text work best for laser engraving on metal, especially for small items like jewelry or tools.

4. Adjust Power and Speed Settings

Finding the right settings for power, speed, and frequency is critical in laser engraving metal. These settings determine how deep and dark the engraving will be. Fiber lasers, like SA Lasers’ Polymetal 30-watt, often require lower speeds and higher power for deeper marks on harder metals.

Recommended Settings:

• Power: Start with 50-80% for metals; adjust based on the metal type and desired depth.
• Speed: Lower speeds (5-20%) for deeper engravings.
• Frequency: A frequency between 20-50 kHz generally works well for metals.

5. Focus the Laser and Test

Before starting your full engraving, do a test run on a scrap piece of metal. Proper focus ensures that the laser beam hits the metal at the right angle, achieving the sharpest possible engraving. Adjust the focal distance until you reach the desired clarity.

6. Begin Engraving

Once your settings are optimized, you’re ready to engrave. With your fiber laser in position, start the engraving process. Monitor the engraving to ensure consistent quality and depth.

Tips for Laser Engraving Metal Successfully

1. Choose a Quality Machine: For professional results, use a reliable, high-precision machine like SA Lasers’ Polymetal 30-watt fiber laser, which is specifically designed for metal engraving.

2. Experiment with Depth: Different applications call for varying engraving depths. A lighter mark may be suitable for aesthetics, while a deeper engraving is necessary for industrial marking.

3. Consider Adding a Protective Coating: After engraving, you may want to add a clear protective coating to enhance durability, particularly if the engraved item will be exposed to the elements.

4. Follow Safety Protocols: Metal engraving generates fumes and particles. Ensure you are in a well-ventilated area and wear protective eyewear as needed.

Applications of Laser Engraving on Metal

Laser engraving on metal has applications across various industries:

• Jewelry: Create detailed and personalized engravings on rings, pendants, and bracelets.
• Automotive and Aerospace: Mark parts for identification, serialization, and traceability.
