Anodized Aluminum
Community laser settings for this material.
Anodized aluminum has a dyed oxide layer that the laser removes to reveal the shiny bare aluminum beneath, creating high-contrast permanent marks without cutting the metal.
This is one of the few metals a diode laser can mark well. Black anodized gives the highest contrast. Settings are very sensitive — too much power blows out detail. Keep DPI high (300+) for fine text.
