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, messing, or titanium, a good lasergraver can mark, etch, or even deeply engrave metal with precision. I denne veiledningen, 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, messing, og titan. Unlike mechanical engraving, it offers:
✅ Micro-Precision: 0.001mm spot size (f.eks., ComMarker Omni 1) for intricate serial numbers, logoer, or artwork.
✅ Zero Contact: No tool wear, burrs, or material distortion.
✅ Industrial Durability: Resists chemicals, varme, and abrasion.
✅ Hastighet: Engrave a custom knife in 60 seconds or 100 ID tags/hour.
4 Critical Factors When Choosing a Metal Laser Engraver
1. Laser type
| Type | Best for | Avoid If You Need… |
|---|---|---|
| Fiber | Raw metals (stål, Ti) | Under $2K budget |
| MOPA | Fargemerking på rustfritt | Basic etching only |
| UV | Coated metals, smykker | Dyp gravering (>0.2mm) |
2. Power Requirements
- 20W–50W: Marking/text (f.eks., serienummer)
- 60W–100W+: Dyp gravering (0.1–0.5mm) or cutting
- <5W UV: Surface marks on plated/coated metals
3. Arbeidsområde Størrelse
- 110× 110mm: Smykker, small tools
- 300×300mm+: Skytevåpen, industrial plates
4. Pulse Control (MOPA Tech)
Essential forcolor marking stainless steel (black/gold/blue) by adjusting frequency and pulse width.

Proven Laser Settings for Common Metals
Tested parameters forcrisp, consistent results:
| Metall | Makt | Hastighet | Frekv. | Air Assist? |
|---|---|---|---|---|
| Rustfritt stål | 80–100% | 300–500 | 30–60 | Ja |
| Aluminium | 20–50% | 600–1000 | 20–30 | Valgfri |
| Messing | 60–90% | 200–400 | 40–60 | Ja |
| Titanium | 70–100% | 400–700 | 50–80 | Ja |
⚠️Critical: Always run afocus test (ramp method) before production. Material thickness affects beam convergence.

5 High-Profit Metal Engraving Applications
- Custom Knives/Tools: Logoer, ownership marks (50–100W fiber)
- Tumlere & Drinkware: Full-wrap designs (MOPA for color)
- Smykker: Micro-engraving pendants/rings (UV laser)
- Skytevåpen: Compliance markings + personalisering (check ATF rules!)
- Aerospace ID Plates: Barcodes, serier (fiberlaser)
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 (bruk <0.05mm depth).
- Guessing focus → Calibrate with a ramp test for sharpness.
The Verdict
Ja, 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?
EN: Only with thermal spray coatings (f.eks., Cermark). Fiber/UV lasers are required for raw metal.
Q: How deep can a 50W laser engrave metal?
EN: 0.1–0.3mm on steel/brass (after 3–5 passes).
Q: Why does stainless steel turn black when engraved?
EN: MOPA lasers oxidize the surface – adjust pulse width for gold/blue effects.
