What is annealing and what does it have to do with my fiber laser?

Answer

Annealing is the heating of metal (stainless steel, titanium, and chrome) to create an oxide layer. Depending on the thickness of the oxide layer, the results can range from black to other various colors. When done correctly, there will be no surface deformation when using a fiber laser engraver.
