Longer B1 — Anodized Aluminum

What speed should I use to engrave Anodized Aluminum on the Longer B1?

The top-rated community setting uses 1500 mm/min at 80% power. Diode lasers remove the anodised layer cleanly, revealing bare silver aluminium underneath. High contrast on black or coloured anodised blanks. Works well for dog tags, tumblers, and phone cases. No Cermark needed on anodised aluminium.

Can the Longer B1 cut Anodized Aluminum?

A 22W diode laser can mark or engrave metal surfaces but cannot cut through them — metal cutting requires a much higher-powered laser or a plasma cutter.

How many passes does the Longer B1 need to engrave Anodized Aluminum?

All settings here use a single pass. Confirm focus and do a small test burn before committing to your final design.

Do I need air assist for Anodized Aluminum on the Longer B1?

Air assist is not flagged as required for these settings, but it is good practice during cutting operations to keep the lens clean and reduce char buildup.

What DPI should I use to engrave Anodized Aluminum on the Longer B1?
