G3-3D Series | Industrial 3D Galvo Head for Curved Surface Laser Processing

G3-3D 3D Galvo Scanner for Curved Surface Laser Processi

G3 3D adopts the third axis module developed by JCZ, which has faster response speed, faster zoom and more stable. The system has strong anti-interference ability, high reliability, good linearity, high repetition precision and short response time. The system adopts integral structure with small volume, light weight and good sealing performance to ensure the stability under long working conditions. G3 3D is suitable for complex curved surface processing, 3D deep carving, high power cutting, drilling, laser micro processing, 3D printing, etc. According to the different wavelength and mirror size, it can process various materials such as metal, leather, rubber, wood, bamboo products, ceramic tile, plastic, marble, jade and other materials.

Why Use a 3D Galvo Scanner Instead of a Standard 2D Galvo?

A conventional 2D galvo controls the laser beam across an XY plane. This works well when the workpiece remains close to one focal plane.

When the surface contains curves, slopes, steps or changing heights, part of the marking area can move outside the usable focus range.

A 3D galvo scanner adds active control of the focal position in the Z direction. This allows the system to compensate for surface-height changes without relying entirely on mechanical repositioning of the workpiece.

Dynamic or adjustable Z-focus is also a central feature of competing industrial 3D scan systems from RAYLASE and SCANLAB, where the third optical axis is used to process curved, stepped or different-height surfaces.

Post-Focusing 3D Galvo Architecture

The G3-3D uses a post-focusing architecture with a replaceable F-theta lens.

The third-axis module adjusts the focus position while the X/Y galvanometer mirrors control the laser path across the workpiece.

JCZ currently specifies different Z adjustment ranges according to wavelength and lens configuration:

Actual usable processing range depends on the lens, beam diameter, laser source, surface geometry and required spot quality.

Post-focusing 3D systems are particularly useful when you need Z adjustment while retaining an F-theta-based optical architecture. RAYLASE uses a similar general concept in its FOCUSSHIFTER RD-14, combining an F-theta lens with dynamic optical Z adjustment for processing workpieces with different height levels.

Select the 3D Galvo by Laser Wavelength

A machine builder should not select a 3D galvo scanner head from mechanical dimensions alone.

The complete optical system must match the laser wavelength.

1064nm 3D Galvo Scanner

The 1064nm configuration is intended for compatible fiber-laser systems.

Typical machine directions include:

• Metal marking
• Curved metal component identification
• Mold engraving
• Deep engraving
• Hardware processing
• Automotive component marking
• Industrial traceability

The current G3-3D 1064nm configuration provides the widest published Z adjustment range among the three wavelength options on this page.

355nm 3D Galvo Scanner

The 355nm configuration is intended for UV-laser systems where precision processing and smaller optical features are required.

Potential machine directions include:

• Precision plastic marking
• Electronics
• Selected glass processing
• Fine identification
• Micro-processing
• High-resolution codes

The galvo scanner, F-theta lens and other optical components throughout the beam path must all be compatible with 355nm.

532nm 3D Galvo Scanner

The 532nm version can be configured for compatible green-laser applications.

This wavelength is commonly evaluated for selected precision-processing applications where the material response differs from conventional 1064nm fiber-laser processing.

For all three versions, select the wavelength based on the laser process and material rather than the material name alone.

Curved Surface Laser Processing

The primary reason to use the G3-3D is the ability to process surfaces that do not remain within one fixed focal plane.

Typical workpiece geometry can include:

• Curved housings
• Cylindrical or partially cylindrical parts
• Domed components
• Sloped surfaces
• Stepped structures
• Molds with changing height
• Irregular industrial parts
• Components with raised or recessed features

Industry 3D scanning systems use Z-axis focus adjustment for the same reason: maintaining the focal position as surface height changes. RAYLASE specifically identifies curved, sloping and stepped surfaces as core 3D laser-marking applications.

For machine manufacturers, the actual surface profile should be evaluated before specifying the scanner. Send a 3D drawing, STEP model or representative sample whenever possible.

3D Deep Engraving

The G3-3D can also be evaluated for 3D laser engraving and deep-engraving systems.

As material is removed layer by layer, the processing surface moves deeper into the workpiece. A third focus axis allows the system to adjust the focal position during the engraving process instead of relying only on a fixed initial focal plane.

Typical equipment directions include:

• Mold engraving
• Relief engraving
• Textured surfaces
• Tool identification
• Decorative metal processing
• Layer-based 3D engraving

The achievable depth, surface finish and cycle time depend on the laser source, material, lens, processing strategy and required geometry.

Laser Cutting, Drilling and Micromachining

JCZ also positions G3-3D for project-based laser cutting, drilling, micromachining and 3D-processing applications.

For these processes, controller selection should consider more than scan speed.

This is especially important for precision drilling and cutting, where consistent focal position can directly affect the geometry of the processed feature. RAYLASE similarly emphasizes Z-focus control for laser drilling and cutting through materials of different thicknesses.

XY2-100 Interface for Machine Integration

The G3-3D uses the XY2-100 communication interface.

For an OEM machine project, confirm compatibility between:

Controller → Scanner Protocol → Z-axis Control → Software → Calibration

before finalizing the electrical and optical design.

Do not assume that replacing a standard 2D galvo with a 3D galvo is only a mechanical change. A 3D system may also require changes to controller configuration, software, optics and calibration.

G3-3D vs GO3D-T: Which 3D Galvo Should You Choose?

JCZ also provides the GO3D-T 3D Galvo Scanner Head for more demanding 3D laser-processing projects.

The current GO3D-T range provides multiple aperture options, wavelength configurations and marking speeds up to 6000 mm/s depending on configuration, while G3-3D is positioned by JCZ as an entry-level post-focusing 3D galvo solution.

In general:

Final selection should be based on the complete laser and optical configuration.

FAQ

What is a 3D galvo scanner head?

A 3D galvo scanner controls laser positioning in X and Y while adding a Z-direction focus adjustment. This allows the laser focus to follow changes in workpiece height and makes the system more suitable for curved, stepped and non-flat surfaces.

Can G3-3D process curved surfaces?

Yes. G3-3D is specifically positioned for 2D flat and 3D curved-surface processing and includes a third-axis focusing module for Z-direction adjustment.

Which wavelengths does G3-3D support?

The current product specification lists 1064nm, 532nm and 355nm configurations.

Does G3-3D support XY2-100?

Yes. The current specification lists XY2-100 as the interface.

What is the maximum marking speed?

JCZ currently specifies a marking speed of 4000 mm/s and positioning speed of 10000 mm/s for G3-3D.

Is G3-3D a complete 3D laser marking machine?

No. It is a 3D galvo scanner head. A complete system still requires a compatible laser source, controller, software, optics and other machine components.

Configure G3-3D for Your Laser Machine

The correct 3D galvo scanner head for curved surface laser processing should be selected from the complete machine architecture rather than from scanner speed alone.

Provide JCZ with your laser wavelength, beam diameter, required processing field, Z-height variation, surface geometry and process requirements.

We can then evaluate whether the G3-3D, GO3D-T or another JCZ 3D scanning solution is the more appropriate direction for your machine.
