If you’re thinking about laser printing on metal, the first question you’ll probably ask is: Can a laser engraver really handle that? The short answer—absolutely yes. Whether you’re working with stainless steel, aluminium, laiton, or titanium, a good graveur laser can mark, graver, or even deeply engrave metal with precision. Dans ce guide, we’ll break down what kind of laser you need, which metals work best, what specs actually matter, and how to choose a laser engraver that gives you professional results—without breaking the bank.
Why Laser Engraving Dominates Metal Marking
Laser engraving is the #1 method for permanent metal marking on stainless steel, aluminium, laiton, et titane. Unlike mechanical engraving, il propose:
✅ Micro-Precision: 0.001mm spot size (par exemple., ComMarker Omni 1) for intricate serial numbers, logos, or artwork.
✅ Zero Contact: No tool wear, burrs, or material distortion.
✅ Industrial Durability: Resists chemicals, chaleur, et abrasion.
✅ Vitesse: Engrave a custom knife in 60 seconds or 100 ID tags/hour.
4 Critical Factors When Choosing a Metal Laser Engraver
1. Type de laser
| Taper | Idéal pour | Avoid If You Need… |
|---|---|---|
| Fibre | Raw metals (acier, Ti) | Under $2K budget |
| MOPA | Marquage couleur sur inox | Basic etching only |
| UV | Coated metals, bijoux | Deep engraving (>0.2millimètre) |
2. Power Requirements
- 20W–50W: Marking/text (par exemple., Numéros de série)
- 60W–100W+: Deep engraving (0.1–0.5mm) ou couper
- <5WUV: Surface marks on plated/coated metals
3. Taille de la zone de travail
- 110×110mm: Bijoux, petits outils
- 300×300mm+: Armes à feu, industrial plates
4. Contrôle de l'impulsion (MOPA Tech)
Essential forcolor marking stainless steel (black/gold/blue) by adjusting frequency and pulse width.

Proven Laser Settings for Common Metals
Tested parameters forcroustillant, consistent results:
| Métal | Pouvoir | Vitesse | Fréquence. | Assistance aérienne? |
|---|---|---|---|---|
| Acier inoxydable | 80–100% | 300–500 | 30–60 | Oui |
| Aluminium | 20–50% | 600–1000 | 20–30 | Facultatif |
| Laiton | 60–90% | 200–400 | 40–60 | Oui |
| Titane | 70–100% | 400–700 | 50–80 | Oui |
⚠️Critical: Always run afocus test (ramp method) before production. Material thickness affects beam convergence.

5 High-Profit Metal Engraving Applications
- Custom Knives/Tools: Logos, ownership marks (50–100W fiber)
- Gobelets & Drinkware: Full-wrap designs (MOPA for color)
- Bijoux: Micro-engraving pendants/rings (Laser UV)
- Armes à feu: Compliance markings + personnalisation (check ATF rules!)
- Aerospace ID Plates: Barcodes, serials (laser à fibre)
4 Costly Mistakes to Avoid
- Using CO₂ on bare metal → Leaves faint/unreadable marks.
- Skipping fume extraction → Metal vapor is toxic (install exhaust + filter).
- Engraving coated metals too deep → Peeling/cracking (utiliser <0.05mm depth).
- Guessing focus → Calibrate with a ramp test for sharpness.
The Verdict
Oui, laser engravers excel with metal – butfiber/MOPA lasers are essential for professional results. For under $5K, models like theComMarker B6 deliver precision rivaling industrial machines.
🔥Hot Tip: Need deep engraving? Prioritizepulse energy over wattage. A 50W MOPA often outperforms 100W non-MOPA lasers.

FAQ Section (Schema-Rich)
Q: Can diode lasers engrave metal?
UN: Only with thermal spray coatings (par exemple., Cermark). Fiber/UV lasers are required for raw metal.
Q: How deep can a 50W laser engrave metal?
UN: 0.1–0.3mm on steel/brass (after 3–5 passes).
Q: Why does stainless steel turn black when engraved?
UN: MOPA lasers oxidize the surface – adjust pulse width for gold/blue effects.
