Atomstack X7 Pro 50w (new flagship model similar to A10 Pro S10 Pro) laser cutter & engraving machine. 

In this video we will test this laser engraving with different metals, such as steel, stainless-steel, aluminium, brass, iron...
Our main trick if the surface is very reflective is to paint it black, (mate black the smoother the surface the better, but a permanent marker will suffice). Examples: CerMark, Laserbond... black primer and other paints can work but it's better that reflect the laser because if not it will burn on the surface and might not look as good or the material can melt. 

We also show case another interesting method to remove and clean rust from iron or other metallic materials.
