Getting clean, deep engravings on metal takes more than just a powerful laser. With the  ComMarker Titan 200W and the right setup, you can achieve precise, professional results. Here’s how to do it.

What Is Deep Metal Engraving?

Deep metal engraving is a laser process that removes material layer by layer to create a permanent, tactile cavity in metal.

Unlike surface marking, which only affects the top layer, deep engraving physically cuts into the material.

Depth comparison:

• Surface marking: ~0.01–0.03 mm
• Standard engraving: ~0.05–0.1 mm
• Deep engraving: 0.1 mm and deeper

Key Settings for Deep Metal Engraving

1. Laser Power

Use Higher wattage = faster depth

2. Speed

Lower speed = deeper engraving in one pass.

Higher power settings will be needed for engraving metals. Start at around 80% power and adjust based on the material’s response.

3. Frequency (kHz)

Lower frequency → stronger pulses → deeper cuts.Adjusting the frequency and Q-pulse helps refine the engraving process.

Higher frequency typically results in smoother marks, while lower frequency gives more depth.

4 Hatch Spacing (Line Interval)

Smaller spacing = more material removed

5 Number of Passes

Depending on the material’s thickness and hardness, you may need to run multiple passes to achieve the desired depth.

Multiple passes are essential.

You can use the continuous to let the laser continue working until you reach the desired depth.

6 Focus Adjustment (VERY IMPORTANT)

Gradually lowering Z-axis as engraving goes. Once per 30 min is recommended.

Why Choose the ComMarker Titan 200W for Metal Engraving?

The ComMarker Titan 200W stands out because of its strong power, which is essential when engraving metals or other tough materials. Compared to smaller machines, the Titan provides:

  • Increased depth capability: A higher power output allows for deeper engravings, which is crucial when working with metals, such as aluminum, stainless steel, and even harder materials.

  • Faster engraving times: With its higher wattage, the Titan reduces the time needed to finish detailed engravings, making it ideal for large projects or for engraving in high volumes.

  • Flexibility in engraving: Whether you need detailed surface etching or deep engravings, the 200W laser can achieve both with fine precision.

How to Perform Deep Metal Engraving with the ComMarker Titan 1

To get the best results with the ComMarker Titan 1 for deep metal engraving, follow these steps:

Step 1: Choose the Right Material

First, ensure that the material you are working with is suitable for deep engraving. The ComMarker Titan 1 works well with metals like brass, aluminum, and stainless steel, making it perfect for industrial applications and artistic projects.

Step 2: Use the Appropriate Lens

When engraving large areas or working with thick metal sheets, use a smaller field lens to maintain maximum laser intensity. This helps ensure that your engravings are consistent and deep across the entire material.

Step 3:  Use Proper Settings

The key to deep metal engraving is finding the right combination of power and speed. For deep engravings, you need to increase the power setting and adjust the speed accordingly to allow the laser to penetrate the material effectively.

To maintain consistency and prevent debris buildup, perform regular cleaning passes to clear dust and residue from the engraving area, ensuring stable and repeatable results.

The ComMarker Titan 1 can be set to higher power levels than most lower wattage lasers, which makes deep engraving far more efficient. A 20W fiber laser can take 8 hours to engrave two sides of a single coin, while higher power systems complete the same job much faster and with better consistency.

Step 4: Adjust Focus for Deeper Engraving

Once your settings are adjusted, make sure to focus the laser on the material’s surface properly. The ComMarker Titan 1 comes with an intuitive Z-axis focus adjustment to help you fine-tune the focus and achieve the deepest engravings.

Step 5: Design for Depth (How Deep Engraving Actually Works)

Deep engraving is built layer by layer rather than being created in a single pass.

To achieve depth, you repeatedly engrave the same design, gradually removing material until the desired groove or cavity is formed.

This allows you to create text or vector shapes with a noticeable, touchable depth.

In some cases, if you continue the process long enough, you can even cut through or drill into the material following the design path. This is the fill strategy commonly used in laser metal cutting workflows.

You can also reverse this process. Instead of engraving the text itself, you can repeatedly engrave the surrounding area, leaving the text raised. This creates an embossed or relief effect, where the design appears elevated from the surface.

For more advanced results, use grayscale images. The laser adjusts its scanning area based on brightness: darker areas engrave deeper, while lighter areas are less touched. This allows for smooth depth transitions and makes it possible to create realistic 3D relief engraving effects.

Step 6: Start the Engraving and Monitor the Process

Lower the laser head approximately every 30 minutes to maintain optimal focus

Tips: How to Get Best Results when using Fiber Laser for Deep Metal Engraving

  • Test before the final engraving: Always run a few tests on scrap metal before moving to the actual project. This helps you fine-tune the settings and avoid wasting material.

  • Use the correct lens: The 200mm lens is ideal for larger projects and deeper engravings, while the 110mm lens offers more precision for smaller, detailed work.

  • Choose the right metal: Softer metals like aluminum are easier to engrave, while harder metals like stainless steel may require more power or additional passes.

  • Work in a well-ventilated area: Metal engraving often produces fumes, so ensure you have proper ventilation or a fume extraction system in place.

  • Find the best parameters for fiber laser engravers

  • Choose a high-power fiber laser engraver

Conclusion

The ComMarker Titan 200W laser engraver is a powerful tool for deep and precise metal engraving. By using material tests and adjusting settings based on your material type, you can achieve high-quality, professional results in a fraction of the time compared to lower-powered machines.

Whether you’re engraving metal for personal projects or professional applications, the ComMarker Titan offers the strength and precision needed to bring your designs to life.
