How I engrave anodized aluminum:

Take the piece you want to engrave and color it in a dark watercolor from a paintbox. In this example I took a dark blue.

Don’ make the surface too wet or too much light/dark mixed. Not good.

This way is much better:)

While the color dries prepare your Image or Vectorgraphic for the geode and save the file. I took Aspire to make it – Inkscape can do the job as well.

I always check my gcode-file before I start. Here you can see and check wheather everything is fine or not.

I choose : Movespeed 3000

Engravespeed 1500

and Z height is (accidentially) 1 should be zero for perfect focus – so I gave command G92 Z1 to set the height before I started.

Adjust focus on the right height for the surface of the shield and start engraving.

NEVER FORGET PROTECTION GLASSES

My logo has a size of roundabout 60x20mm – so it took only 4minutes.

When the job is done – wash off the remaining color. Here we go – finished 🙂

Using Dry Moly Lube for engraving (marking) stainless steel using the Endurance 10W Diode Laser by Florian Kelsch

You can get the Dry Moly Lube on many different platforms. It should not matter which brand you are buying. I’ve got mine from E-Bay.

First of all you simply spray a layer of the Dry Moly Lube at the piece of stainless steel and let it dry (takes only a couple of seconds to dry)

Now you simply engrave it. Im using Lightburn as my laser control software and used the following key settings:

Speed: 3mm/s

Power: 100%

Pattern: Crosshatch (bidirectional)

Flood Fill and scanning shapes individual (one letter at a time)

After the job finished, the stainless steel should look something like this:

Now you should clean it with some cleaning alcohol (I’m using Nail Polish remover, like isopropanol 99.9%)

After cleaning it usually looks like this:

You can’t see it on the photos but the Finish after polishing the stainless steel is pretty nice looking.

The Letters are pretty shiny.

I’ve also tried the Dry Moly Lube on a brass medal. The outcome was okay but I didn’t expected the Laser to engrave directly into the brass itself. Need to do more tests with plain brass plates. Will keep you updated.
