Laser engraving and cutting metal is an exciting way to transform ordinary metal pieces into something unique and personalized. Many people believe that only large industrial laser engravers are capable of cutting metal, but what if you could achieve ideal results right with your desktop laser engraver? This guide will show you how laser engraving and cutting metal can be made easy and accessible. Let's get started!
I. Why Choose a Desktop Laser Engraver for Metal?
Desktop laser engravers are a great choice for metal engraving and cutting due to their compact size, precision, and affordability. Here are some advantages of using a desktop laser engraver for your metal projects:
• Compact and User-Friendly: These machines are designed for small businesses or hobbyists. They don't take up much space and are relatively easy to operate, making them ideal for beginners.
• High Precision: Desktop laser engravers provide exceptional accuracy, which is vital for engraving fine details or cutting intricate patterns in metal.
• Cost-Effective: Compared to larger industrial machines, desktop models are much more affordable, allowing small businesses or individuals to access professional-grade engraving and cutting.
• Versatility: Many desktop laser engravers can work with a wide range of materials, from metals like stainless steel and aluminum to plastics and wood, making them versatile tools for various projects.
II. Choosing the Right Desktop Laser Engraver for Metal
Not all laser engravers are created equal. When it comes to laser engraving and cutting metal, certain factors will determine which desktop laser engraver is suited for your needs. Here are a few things to consider:
1. Laser Power
For laser engraving and cutting metal, the power of the laser is crucial. Higher-powered lasers (e.g., 40W, 50W) are better suited for cutting through thicker metals, while lower-powered lasers (e.g., 20W) are ideal for engraving and cutting thinner materials.
2. Laser Type
• Fiber Lasers: Fiber lasers are the go-to choice for engraving and cutting metals. They provide faster engraving speeds, better precision, and can cut through metals with ease.
• CO2 Lasers: CO2 lasers can engrave metal but may not be as effective for cutting metals. These lasers are better suited for engraving on anodized aluminum or other coated metals.
3. Size of the Work Area
The size of your engraver’s work area will depend on the size of the metal pieces you plan to work with. If you're engraving small items like jewelry, a smaller machine will suffice, but larger projects may require a bigger work area.
4. Software Compatibility
The engraver should come with intuitive software that is compatible with a wide range of design files (like SVG, DXF). LightBurn is a popular software option that’s often used with laser engravers for creating intricate designs and ensuring precise cuts.
To meet these needs, the EM-Smart Super laser engraver stands out as an excellent choice. Its high power delivers precision and efficiency, making it perfect for both intricate designs and cutting through thicker metals.
III. Materials for Laser Engraving and Cutting Metal
Laser engraving and cutting metal require the right machine and suitable metal materials. The most common metals for laser engraving are:
• Stainless Steel: Durable and corrosion-resistant, ideal for industrial applications, tools, and custom signage. Requires higher laser power for deep engraving.
• Aluminum: Lightweight and easy to work with, great for engraving logos, serial numbers, and product IDs. It needs lower power but may require adjustments due to its reflective surface.
• Brass & Copper: Popular for jewelry and decorative pieces, offering unique textures and colors. They require precise settings to avoid discoloration from excessive heat.
• Anodized Aluminum: Offers high-contrast engravings with its protective coating, perfect for industrial marking like tags and badges.
• Titanium: Used for high-end applications like medical or aerospace components. It’s strong but requires high-powered lasers for engraving or cutting.
When selecting your metal, always consider its thickness and composition, as these factors determine the appropriate settings for the laser machine.
IV. Step-by-Step Guide to Laser Engraving and Cutting Metal
Now that you’ve selected the perfect desktop laser engraver, let’s walk through the steps to laser engrave and cut metal:
Step 1: Material and Equipment Setup
Before starting, ensure your materials and equipment are properly set up. Place your metal piece securely on the workbed and connect the EM-Smart Super laser engraver to your PC. Install the necessary software and check that all components are functioning correctly.
Step 2: Prepare Your Design
Create or select your design using software like LightBurn. Whether you're engraving a logo, text, or custom artwork, ensure that your design is compatible with metal engraving. Adjust the size and positioning of the design to fit your material, and make sure the lines are solid to avoid incomplete cuts. You can also import existing design files (such as SVG or DXF) for more complex projects.

Step 3: Focus Adjustment
Adjust the focus of the laser according to the thickness of the material being engraved. Proper focusing ensures clarity in your engravings and prevents excessive burning or distortion.
Step 4: Adjust Laser Settings
Use the accompanying software to set up your design file and adjust parameters such as power, speed, frequency, and hatch settings based on your material type and desired outcome. Recommended Settings for Different Metals
Here are suggested settings for various metals using a fiber laser:
| Metal Type | Power (%) | Speed (mm/s) | Frequency (kHz) | Hatch | Line Space (mm) |
| Stainless Steel | 50 | 300 | 30 | 1 | 0.01 |
| Aluminum | 100 | 2000 | 55 | 1 | 0.03 |
| Brass | 100 | 200 | 45 | 1 | 0.001 |
| Copper | 80 | 150 | 40 | 1 | 0.02 |
| Anodized Aluminum | 60 | 800 | 30 | 1 | 0.01 |
Step 5: Material Testing
Before starting the final engraving, it's essential to test the material. This ensures that the settings are correct for the type of metal you're working with. Use a small test area to check the engraving depth, clarity, and whether there’s any unwanted burning or distortion. Adjust the power, speed, and frequency settings as needed based on the test results to achieve the best quality engraving. Always perform this test on scrap material first to avoid wasting your main workpiece.
Step 6: Start Engraving or Cutting
Once everything is set up, start the engraving or cutting process. Monitor the machine to ensure the process is running smoothly. It's important to observe the engraving process to ensure that the laser is cutting or engraving at the correct depth.
Step 7: Clean and Finish
After the engraving or cutting is complete, remove the metal piece carefully. Use a soft cloth to wipe off any residue. If you're cutting metal, the edges may need to be cleaned up using a deburring tool to remove any sharp or uneven parts. You can also apply a protective coating to the engraved or cut metal to enhance its appearance and protect it from rust or wear.
