The SL2 (10W blue laser) is excellent for surface marking on certain types of metals:
- ✅ Stainless steel
- ✅ Anodized aluminum
- ✅ Coated / painted metals
For example, you can easily customize tumblers, metal business cards, anodized jewelry, or coated accessories with names, logos, or patterns. The marks are sharp, clear, and permanent.
⚠️ Please note: SL2 is not designed for deep engraving or cutting into raw metals (like solid gold, silver, or copper). For heavy-duty metal etching, a fiber laser would be required.
👉 In short:
- Great for personalization & surface marking on jewelry and coated metals
- Not suitable for deep carving into bare solid metals
