Gweike G3 Dual Laser – One Machine, All The Materials

The world of laser engraving is evolving fast, and Gweike’s latest flagship – the G3 Dual Laser – is proof of that momentum. Combining a 60 W MOPA fiber laser, a 40 W diode laser, and a smart visual positioning system, the G3 is built to tackle virtually any material you can throw at it – metal or non-metal – with precision, automation, and power.

From metal color marking and deep engravings to detailed cuts on wood, leather, acrylic, and more, G3 isn’t just a multi-material engraver. It’s a hybrid beast designed to streamline workflow, scale production, and unlock creative freedom – whether you’re a maker, workshop owner, or full-blown business.

Two Lasers, One Workflow

At the heart of the G3 is its dual-laser configuration, which utilizes the following:

60 W MOPA Fiber Laser: Excellent for engraving on stainless steel, titanium, aluminum, brass, and even precious metals. With its pulse control, the MOPA unit delivers stunning black or rainbow-like color marking, as well as deep engraving and precision etching – even on curved surfaces.

40 W Diode Laser: The non-metal material powerhouse, capable of cutting and engraving wood, acrylic, rubber, leather, and even stone. The diode laser’s wide compatibility makes it the perfect tool for crafts, decor, signs, packaging, and DIY personalization.

Unlike most machines requiring manual switching between laser heads, G3 automatically switches based on your material or settings—saving time and removing guesswork. You can go from marking stainless steel tumblers to cutting a thick piece of acrylic without changing machines or heads.

Vision-Powered Precision

The G3’s built in ultra-wide fisheye camera enables accurate, real-time positioning. Whether you’re batch-engraving small items such as tags or placing artwork on oddly shaped pieces, the camera helps you preview, adjust, and align your project effortlessly before starting the job.

This is especially helpful for businesses doing batch jobs or personalization, where precision placement can make or break a product. No more measuring twice and hoping for the best — the G3 shows you exactly where your artwork will land.

Made for Real Work

The G3 is more than just a desktop engraver — it’s a machine built for production. The rugged aluminum frame and modular design feel ready for factory floors. You can even add a conveyor belt system to support automatic feeding, making it ideal for serial production of tags, labels, or product panels.

It also features smart auto-focus and is able to detect material thickness automatically and adjust for optimal focus. This adds another layer of automation, saving you time and ensuring consistent results across batches.

Software & Ease of Use

The G3 is fully compatible with LightBurn, allowing experienced users of the software full control. For newcomers or quick setups, Gweike’s G-Laser software provides guided workflows and material presets. The camera interface has been designed to integrate cleanly into both platforms.

Setup is straightforward, and initial camera calibration takes just a short time to achieve with the dual-laser system and visual alignment.

Who the G3 is For

The G3 is perfect for:

• Makers who want a single machine to handle everything from wood to stainless steel
• Workshops producing custom items or limited-run product batches
• Professionals needing color laser engraving on metal
• Creative entrepreneurs looking to expand their material range and output
