Engraving vs Etching
While sometimes used interchangeably, etching and engraving are unique processes which provide distinct aesthetics and different depths. Etching the metal provides a light surface alteration, and engraving provides a deeper surface alteration. Similar to engraving, etched materials can be made by routing out a small amount of material, but etching can also be realized through chemical processes.
There are a number of methods to achieve each process: from laser-etching to sandblasting, cnc-engraving to laser marking and more. Each of these processes has advantages and disadvantages, and can be selected based on the metal alloy and performance, as well as the end result and defining aesthetic.
