Gweike G3 MOPA Fiber Dual

What the Gweike G3 MOPA Fiber Dual can make

The Gweike G3 MOPA Fiber Dual is a fiber laser: built for marking and engraving metals (stainless steel, aluminium, brass, gold, silver) and some plastics, quickly and permanently. It is not a cutter for wood or acrylic.

It has a rated laser power of 60 W, a work area of 170 × 170 mm (6.7 × 6.7 in) and a top engraving speed of 15,000 mm/s.

The brand states that it cuts up to 20 mm of wood or plywood; thicker material takes several passes, and results depend on the material and air assist.

It works with a camera for positioning designs on the material, autofocus, support for a rotary attachment to engrave tumblers and other round objects and LightBurn software.

In the United States the Gweike G3 MOPA Fiber Dual sells for $4,299, above the median of $2,600 across 26 fiber laser engravers with a US price, among the premium models.

Gweike G3 MOPA Fiber Dual safety and compliance

The Gweike G3 MOPA Fiber Dual has a fully enclosed design.

Every laser engraver makes smoke and fumes: run it with an exhaust to the outdoors or a fume purifier. Never cut PVC or vinyl, which release corrosive chlorine gas.

The brand's listing does not state FDA compliance. Laser products sold in the United States must meet the FDA's laser performance standard (21 CFR 1040.10) and be reported to the FDA, which issues an accession number; ask the seller for it before buying in the US.
