Ortur Laser Master 3 — Anodized Aluminum

Ortur's own capacity test and community data: anodized/painted aluminum at 5000 mm/min, 100% power gives good contrast with shiny finish after wiping. Machine max is 20,000 mm/min. For finer detail reduce speed to 3000–4000 mm/min.

Removes anodising cleanly to reveal bright aluminium. No Cermark or coating needed. The LM3 handles anodised aluminium as well as much more expensive machines at this task. Great for dog tags, tumblers, and phone cases. Use a rotary for tumblers.

Works on black anodized. 10W gives lighter mark than 20W+ machines.
