This listing is for a Gweike G3 laser engraver, featuring both a 50W fiber laser and a 20W diode laser. It is approximately 6 months old and is in perfect working condition, like new. I bought it for $3,800 before the rotary and shipping. The sale includes a rotary attachment, ideal for cylindrical objects like tumblers. The fiber laser is capable of deep engraving on all metals, including steel and aluminum, while the diode laser excels with materials such as wood, leather, and acrylic. It also comes with a bunch of aluminum cards to engrave and some acrylic plaques.
