Today we're going to look at engraving metal with a CO2 laser. Although you can't technically engrave metal with a CO2 laser, you can use your CO2 laser to etch metal otherwise known as "marking" the metal. Although the metal isn't actually removed as it would be in an engraving process, it is permanently marked, which works well for many applications, although it won't give you deep laser engravings. This process also works well for etching metal with a diode laser engraver.
