[Lab] printing on aluminium

[Paul & Andrea Mumby]

You can mark annodized aluminum quite easily using a laser cutter/engraver
(such as the one at modlab). Resulting in a nice permanent and durable
image.

See http://www.instructables.com/id/Laser-Etching-Anodized-Aluminum/ for
one example (using an epilog laser same as modlab).
