Everything you need to know about laser marking (etching) using an Endurance 20 watt (20000 mW) 445 nm double-beam laser attachment.
First of all I want announce that engraving on metals is possible with a 20 watt continous visible 445 nm laser attachment.
The second positive thing is that the process is quite simple.
Just cover the surface with engraving pasta and you are all set. Engrave and enjoy!
Now with a 20 watt laser you may mark on any metalic surfaces: stainless steel, aluminum, brass and copper.
For laser etching we use special engraving pasta (analog of Cermark LMM-6000).
Average parameters for laser marking
|Material||Amount of repeats||Speed in g-code||Special conditions|
|Aluminum||5||5||polished and sanded|

Recommended pastas and chemicals for laser etching (marking)
Litoscript metal black
Grout white for marble
We plan to make more experiments with different chemicals, such as: Lube with Molybdenum-disulfide (MoS2) and others.
