We buy blue anodized boxes and use a Boss laser to blast the artwork.

That saves a ton of hassle with labels and silkscreening.I tried using it to cut patterns into copperclad FR4, instead of dremeling. It didn't cut copper very well and burned the FR4. Maybe some fast pulsed laser would work better.
