| Spec | Fiber / MOPA | CO2 + spray |
|---|---|---|
| Bare stainless/brass | Native — engrave, anneal, color (MOPA) | Only via marking spray/paste per part |
| Mark permanence | In the metal; survives abrasion | Bonded surface layer |
| Per-part consumables | None | Spray cost + prep time each part |
| Speed on metal | Galvo — thousands of mm/s | Gantry speeds |
| Beyond metal | Metal-only in practice | Full organics catalog |
| Coated shortcuts | Also excellent | Poor on coatings |
Specs standardized from published manufacturer data and consistent owner reports — we don’t operate a lab.
If bare-metal goods are the product, fiber is not the upgrade — it is the machine. Native 1064nm marking needs no consumables, runs at galvo speeds, and on a MOPA source adds anneal blacks and color no spray can imitate.
The CO2-plus-spray route is a legitimate bridge for occasional metal jobs inside an organics business — just cost the spray and prep into every part. And remember the third path: anodized and powder-coated blanks mark on an ordinary diode, which is where most metal product lines actually start.
