Gweike G3 Dual Laser Engraver (Fiber + Diode)

Gweike G3 Dual Laser Engraver (Fiber + Diode): One Desktop Machine for Metal Marking and Non-Metal Cutting

If you’ve ever wished you could handle both metal engraving and non-metal cutting without buying two separate machines, the Gweike G3 is built for exactly that.

The Gweike G3 combines a 1064nm fiber laser (for metals and fine detail marking) with a 450nm diode laser (for popular non-metal materials like wood, leather, and acrylic). This dual-source design makes it a practical choice for small businesses, makers, studios, and workshops that need broad material coverage in one enclosed desktop system.

1) Why the G3 is different: Dual laser, real business versatility

Many desktop machines are excellent for either metal marking or non-metal engraving/cutting—but not both. With the G3, you can:

• Engrave metals with the fiber laser (stainless steel, aluminum, brass, precious metals, etc.)

• Cut/engrave non-metals with the diode laser (wood, leather, MDF, felt, some dark acrylic, paper, and more)

This reduces equipment cost, saves workspace, and simplifies your workflow if you run mixed-material jobs.

2) MOPA color marking (for creators and premium products)

For users who want standout metal results, the G3 includes MOPA options designed for permanent, vibrant color marks on metals (including stainless steel and titanium alloys). Color marking is especially useful for:

• Premium product branding

• Personalized gifts

• Small-batch jewelry and accessories

• High-impact logos and decorative patterns on metal parts

3) Built-in camera positioning + autofocus (faster setup, fewer mistakes)

The G3 integrates a smart camera system to help align your work and start the engraving workflow more efficiently. Combined with autofocus, it’s designed to reduce setup time—especially helpful for repeat orders, jigs, and batch production.

4) Batch production support: expandable working area with a conveyor option

If you plan to scale beyond single items, the G3 supports a larger work area using a conveyor (ideal for repeated patterns, longer materials, and faster throughput). This is a practical “upgrade path” from hobby output to small business production.

5) Rotary engraving ready (tumblers, rings, cylinders)

The G3 supports rotary engraving for cylindrical and curved objects—perfect for:

• Tumblers and cups

• Rings and bracelets

• Bottles

• Round industrial components

6) Enclosed design + ventilation (cleaner, safer workspace)

The G3 uses a fully enclosed structure with an OD5+ protective shield and built-in ventilation to help block dust/smoke and reduce laser light leakage—an important factor for workshops and indoor studios.

9) Who should consider the G3?

The Gweike G3 is a strong fit if you:

• Want one desktop machine to cover both metal engraving and non-metal cutting/engraving

• Run a personalization business (names, logos, serials, QR codes, gifts)

• Sell premium metal products and want color marking capability (MOPA versions)

• Need camera positioning + autofocus to speed up setup and reduce alignment errors

• Plan to scale with rotary + conveyor accessories for production workflows
