When it comes to precision, efficiency, and versatility, few tools match the performance of a laser cutter for metal. Whether you're working with stainless steel, aluminum, titanium, or other alloys, modern metal cutting laser machines open a new world of creative and industrial possibilities. In this guide, we’ll explore four of the most effective laser cutting and engraving methods used in the metalworking industry, with pro tips, recommended settings, and a spotlight on the Monport GA 100W MOPA Fiber Laser — a powerhouse tool built for professionals.
Why Choose a Laser Cutter for Metal?
A laser cutter for metal utilizes a high-powered, focused beam of light to engrave or cut through material with surgical precision. Unlike mechanical methods, laser systems are contactless, reducing wear while delivering unmatched detail and speed. From small businesses to large-scale manufacturers, a metal cutting laser is a staple for logos, custom products, industrial parts, and artwork.
Method 1: Fiber Laser Marking (Surface Engraving)
Fiber laser marking is ideal for surface-level detail. With a metal cutting laser like the Monport GA 100W, you can mark logos, barcodes, and serial numbers on most metals.
Recommended Settings:
-
Material: Stainless Steel
-
Power: 20–30%
-
Speed: 800–1200 mm/s
-
Frequency: 25–30 kHz
-
Line spacing: 0.03–0.05 mm
Tips:
-
Use multiple passes for darker, deeper marks.
-
Focus accuracy is key — Monport’s auto-focus feature eliminates guesswork.
-
Clean metal surface before marking to avoid residue buildup.
Method 2: Precision Metal Cutting with MOPA Fiber Laser
Need to slice through stainless steel or aluminum? The laser cutter for metal powered by a MOPA fiber laser excels in this category. With the Monport GA 100W, cutting thin sheets of metal is accurate, clean, and fast.
Recommended Settings:
-
Material: Aluminum (1mm–2mm)
-
Power: 80–100%
-
Speed: 200–400 mm/s
-
Frequency: 20–50 kHz
-
Assist Gas: Air or Nitrogen
Tips:
-
Always use a proper metal cutting laser lens — standard lenses wear faster with reflective metals.
-
Use air assist or nitrogen to reduce oxidation and burn marks.
-
Keep the focal height precise — Monport’s autofocus keeps everything aligned.
Method 3: Deep Engraving for Industrial Components
Deep engraving is essential for tools and components exposed to harsh conditions. With a laser cutter for metal, you can engrave multiple layers deep while preserving detail.
Recommended Settings:
-
Material: Brass or Steel
-
Power: 60–100%
-
Speed: 200–300 mm/s
-
Passes: 5–10 depending on depth
-
Frequency: 20–50 kHz
Tips:
-
Increase the number of passes instead of maxing power to avoid warping.
-
Cool the metal between passes to reduce overheating.
-
Optimize beam overlap for uniform engraving across curves or uneven surfaces.
Method 4: Color Marking on Stainless Steel and Anodized Aluminum
A favorite among jewelers and artists, color marking allows you to create vibrant hues on metal surfaces using controlled oxidation.
Recommended Settings for Stainless Steel:
-
Power: 10–20%
-
Speed: 200–300 mm/s
-
Frequency: 100–3000 kHz
-
Pulse Width: 50–150 ns
Tips:
-
Use slower speeds for deeper color saturation.
-
Try different frequencies and pulse widths to achieve gold, blue, and purple tones.
-
Always test settings on scrap metal before final application.
With the Monport GA 100W MOPA Fiber Laser, you get wide frequency (1–3000kHz) and pulse width (2–500ns) control — perfect for advanced color marking projects.
