And, though our CO2 laser systems are mainly designed to engrave and cut non-metallic materials, they can also be used to mark on metal with the aid of metal-marking compound. Plastic is very easy to etch or to cut right through. Keep in mind the higher the quality of the graphic you're working with, the better your engraving results. Our entry-level unit is the 30 watt Zing 16 and that system starts from just $7,995 (US price only) -- a small investment for such a powerful piece of machinery!
