Laser etching of metal surfaces using different chemicals

Star Wars logo

Another post about how to make a metal etching using diode lasers

 

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 continuous visible 445 nm laser attachment.
The second positive thing is that the process is quite simple.

 

Just cover the surface with engraving paste (chemical) and you are all set. Engrave and enjoy!

Now with a 20 watt laser you may mark on any metallic surfaces: stainless steel, aluminum, brass and copper.
For laser etching, we use special engraving paste (analog of Cermark LMM-6000 engraving chemical).
