While a 20W fiber laser can indeed mark and engrave metals—especially softer alloys and thin materials—it does have its limitations in depth, vitesse, and versatility compared to higher‑powered systems. For small‑scale metal marking, the ComMarker B6 20W JPT MOPA Fiber Laser Engraver delivers crisp, high‑contrast results on stainless steel, aluminium, et du laiton, making it ideal for jewelry, small parts, et cadeaux personnalisés. Cependant, when you need deeper engraving, faster throughput, or vibrant color marking on a variety of metals—including thick or coated parts—the ComMarker Titan 1 Graveur laser à fibre JPT MOPA (60W–200W) offers the industrial‑grade power, advanced galvanometer, and versatile pulse control to get the job done efficiently.
Understanding Fiber Laser Power for Metal Engraving
How Laser Power Affects Metal Engraving
Laser power dictates both the maximum depth achievable per pass and the engraving speed: higher power allows you to engrave deeper and faster, while lower power often requires multiple passes for the same depth.
Industry Standards and Minimum Requirements
Experts generally agree that marking stainless steel with any fiber laser requires au moins 20 W to produce durable, high‑contrast results without excessive passes. For deeper etching or cutting, powers of 50 W and above are recommended to maintain throughput and reduce cycle times.
20 W vs. Higher‑Power Systems
- 20 W fiber lasers excel at surface marking and shallow engraving on metals like stainless steel, aluminium, et du laiton, with marking speeds up to 15,000 mm/s on fine details.
- 50–100 W fiber lasers enable deeper engraving, cutting thin sheets, and achieving color marking on coated metals in a single pass.
Can a 20 W Laser Engrave Metal?
Capabilities of a 20 W MOPA Fiber Laser
A 20 W JPT MOPA fiber laser can:
- Achieve profond, high‑contrast markings on stainless steel and aluminum with the right coatings or multiple passes.
- Engrave detailed text, logos, and serial numbers in under a second per character at speeds up to 15,000 mm/s.
- Process thin metal parts (≤1 mm) for decorative or identification purposes without heat‑affected zones.
Limitations and Best Use Cases
While capable, a 20 W unit:
- Struggles with cutting metals or engraving thick sections; multiple passes slow throughput and risk work hardening.
- Cannot deliver vibrant color marking on stainless steel in a single pass, which higher‑power MOPA lasers can achieve via pulse‑width modulation.
Exemples pratiques
- Bijoux & Trinkets: Engraving initials, codes à barres, or logos on small pendants and rings with micron‑level precision.
- Plaques & Plaques signalétiques: Shallow engraving (≤0.1 mm) on metal sheets for awards and signage.

Choosing the Right Laser Engraver for Your Metal Projects
- Project Scope: Small‑batch jewelry and plaques → B6. High‑volume, deep engraving → Titan 1.
- Épaisseur du matériau: ≤1 mm → 20 W is fine. >1 mm → upgrade to 60 W+.
- Special Features: Need full‑color marking or 3D depth? Titan 1’s adjustable MOPA pulses are essential.
Setup and Best Practices for Metal Engraving
- Material Prep: Clean surfaces, apply metal‑marking spray for non‑anodized parts.
- Focus Calibration: Use auto‑focus on both B6 and Titan 1 to center the beam.
- Logiciel: LightBurn or EZCad2 for both machines; ensure correct DPI, pouvoir, fréquence, and pulse settings.
Case Studies and Customer Examples
- Independent Jeweler: Reduced marking time by 50 % on sterling silver pendants with the B6, while achieving consistent quality.
- Automotive Supplier: Switched to Titan 1 for part serialization and cutting small SS brackets, meeting industry tolerance standards and halving cycle time.
