Can the laser engrave on metal surface?

Hi fellows,

I had been laser engraving plastic and wood, I noticed when the laser engraver crossed path with screw heads, it does not engrave. I was wondering whether the laser engraver able to engrave on metal surface such as stainless steel or aluminum? Anyone tried?

BoXZY can engrave anodized, painted, or powdercoated metal very well. It is unable to engrave over raw metal as the material absorbs the heat and reflects the majority of the beam.

Oooooo, seriously? I didn't know it could handle anodized metal :D (super excited!)

That is a nice thing to know, keeping that in my back pocket for the future. Thank you Just Helping!

It does an amazing job on anodized metal! I couldn't believe it honestly, it is beautiful. Not sure about clear anodizing, I haven't tried.

Could you post a photo to the forum? I'd really like everyone to see it :)

Definitely. I'll engrave an actual image this week and post it.

I tried the trick of coating a bare Al plate with Dry Graphite (Moly) lube spray and then laser etching and then rinsing off the lube with alcohol and that did not work. I'm interested in if the anodized Al etch works or not. I suspect it needs to be the anodization type that is insulator versus conductive type (so the heat doesn't conduct away as fast).

Any way to get rid of the visible lines?

I'm sure, I didn't even try. These weren't based on the material, it was the engraving path, it did the same thing on the paper test I did.

Graphite lube and Moly lube are two different products. Most likely why it didn't work. It's the Molybdenum base that reacts with the laser, graphite based lube will not react the same way. This is based on my research though, I haven't tried it yet since I'm still trying to find a retailer.
