Laser Challenge #13: Laser Metal Marking- 05.11.13

metalmark0.jpg This post is part of the NOTlabs Laser Challenge: Shawn and I are alternating days with executing and sharing a Laser Cutter involved experiment! And most importantly - we’re supposed to have fun, explore ideas, and it’s less about a fully formed product/concept at the end of the day, but more about seeing where the experiment takes us!

We’ve been meaning to test out the LMM-6000 Metal Marking Material for some time, so Shawn played with it for Laser Challenge #13! Basically ~ you spray a layer down on metal, laser over it, and everywhere the laser hits, a chemical reaction occurs! So Shawn tested things out on his MacBookPro ~ check out the details and process on the next page!

p.s. If you have ideas, or want some laser cutting done, or want to play with us… feel free to use the contact form or leave a comment! And if you’re curious about the laser cutter we’re using, here’s the unboxing.

First testing it all out on the back to get the settings right… NOTlabsEtch11.jpg

Now to do it for real ~ clean off the surface with Denatured Alcohol. NOTlabsEtch01.jpg

Then spray down a layer of the LMM-6000 Metal Marking Material NOTlabsEtch02.jpg

Laser time! NOTlabsEtch05.jpg


When you pull the tape off you can see how much residue there is to wipe away… NOTlabsEtch07.jpg

After wiping it clean… NOTlabsEtch08.jpg

… and you can see how it looks super close up… it’s a nice alternative to etching, since you can get a darker color and not eat into the metal! metalmark1.jpg

I wish I had used Cermark when engraving a friend’s macbook. It turned out OK, but it’s a little hard to see the design unless the light happens to catch it just right. If I ever figure out what to engrave on mine, I’ll definitely use it, thanks for the info.
