Optimal Laser Engraving Settings for Metal

Metal laser engraving requires careful calibration to achieve deep, durable marks without damaging the material. Below are some recommended settings for common metals:

1. General Settings

• Power: Start with 60-80% power and adjust based on test engravings. Higher power may be needed for thicker or harder metals.
• Speed: Aim for 30-50 mm/s to ensure sufficient heat transfer without burning the material.
• Frequency: Use a lower frequency (e.g., 100-200 Hz) for intricate designs and higher frequencies for broader areas.

2. Material-Specific Settings

• Steel: Power: 70-85%, Speed: 40-60 mm/s, Frequency: 150-300 Hz
• Aluminum: Power: 50-70%, Speed: 40-60 mm/s, Frequency: 200-400 Hz (aluminum reflects more light, so lower power is often sufficient)
• Stainless Steel: Power: 65-85%, Speed: 35-55 mm/s, Frequency: 150-300 Hz

3. Tips for Metal Engraving

• Use a focal length of 25-40mm for optimal focus on metal surfaces.
• Apply a thin layer of oil or soap solution to the surface to reduce heat buildup and improve engraving quality.
• Always perform test engravings on scrap material before working on your final project.

Engraving Bone Folders with the LaserHawk LH3

Bone folders, also known as osteotomes, are delicate tools used in surgery and crafting. Laser engraving bone folders allows for precise markings that are both functional and aesthetic. Here’s how to achieve the best results:

1. Preparation

• Clean the bone folder thoroughly to remove any oils or contaminants.
• Ensure the surface is smooth and free of irregularities that could interfere with the engraving process.

2. Recommended Settings

• Power: Start at 30-40% power, as bone is more sensitive to heat than metal. Adjust based on test engravings.
• Speed: Use a slower speed (e.g., 15-30 mm/s) to ensure deep and precise markings.
• Frequency: Opt for a higher frequency (e.g., 300-600 Hz) to create cleaner lines on the bone surface.

3. Additional Tips

• Use a shorter focal length (15-25mm) for engraving bone folders, as they are typically smaller and require precise focus.
• Avoid applying too much pressure during engraving, as this can cause the bone to crack or chip.
• Test your settings on scrap bone material before working on the actual tool.

Fine-Tuning Your Laser Engraving Process

To achieve exceptional results with the LaserHawk LH3, consider these additional tips:

1. Focus and Alignment

Ensure that the laser is properly focused on the surface of the material. Misaligned focus can lead to blurry or shallow engravings.

2. Test Engravings

Always perform test runs on scrap material before starting your final project. This allows you to fine-tune settings without wasting resources.

3. Cooling System Maintenance

Regularly check and clean the cooling system to prevent overheating, which can affect laser performance and longevity.

4. Software Calibration

Calibrate your engraving software to match the specific settings of your LaserHawk LH3 for consistent results across different projects.

FAQs: Frequently Asked Questions About Laser Engraving Settings

1. What are the best laser engraving settings for metal?
   For metal, start with a power setting of 60-80%, speed of 40-50 mm/s, and frequency between 150-300 Hz. Adjust based on test engravings.

2. Can I use the same settings for all types of bone folders?
   No, different bone materials may require adjustments in power, speed, and frequency. Always start with lower settings (e.g., 30-40% power) and incrementally increase as needed.

3. How do I prevent burning during laser engraving?
   Reduce the power output, slow down the engraving speed, and ensure proper focus on the material surface to minimize burning.

4. What is the ideal focal length for metal engraving with the LaserHawk LH3?
   A focal length of 25-40mm is recommended for most metal engraving projects.

5. Can I engrave bone folders without damaging them?
   Yes, as long as you use appropriate settings and take care to avoid excessive heat or pressure during the process.
