Engraving Anodized Aluminum with a Diode Laser (5W–40W)
How the laser ablates the dye layer in anodized aluminum to create permanent white-on-black marks, with settings by wattage, photo engraving technique, and tips for tumblers and curved items.
How to Use These Settings
All settings in this database are starting points for 2–3mm material unless otherwise stated. Before running a full job:
- Run a small test grid on scrap from the same batch of material.
- Confirm your laser is properly focused using the focus tool or a focus-test run.
- Clean your lens with a lens wipe if you haven't done so recently.
- Adjust speed and power in 5–10% increments from the starting point to dial in your specific machine and material.
Laser module optical output can vary 15–20% from the labeled wattage depending on brand and age. If results seem weaker than expected, increase power by 10% before assuming the guide is wrong.
