Help with engraving aluminum 14gauge

[hansepe]

I’m assuming its a clear anodize, so you’re going to need to use something like Cermark, LaserBond 100, or several other things you can search for here in the forums.

Dry moly lube for marking aluminum?

I did try this with some settings inspiration from other posts. Dry moly application: 3 coats Power: Full (Pro) Speed: 100 Passes: trials at 1 and 3 passes Result: Failure, just a couple of specks marked. In another forum I saw someone note success with Thermark improved the THINNER the coat they used. Next time I’ll try 1 coat and see what happens.

Using Mustard Instead of CerMark

I found this video on YouTube… Certainly some (many?) disclaimers on using condiments in your laser cutter… but he seems to be getting some great results. And it’s certainly cheaper than CerMark Laser Engraving/Marking Stainless Steel with…Mustard!

Materials and suppliers

CO2 laser markable Aluminum. This had been posted elsewhere I think, but I could not find it to give credit to the person that found it. Here is what comes in the free sample pack from http://alumamark.com/ [image]

@jbmanning5 answered while I looked a couple of things up. There is more you can search for in the forum too.
