In the world of high-precision laser processing, the Galvo Scanner plays a crucial role in enabling fast, accurate, and stable beam positioning for a wide range of applications. Whether you're marking intricate logos on medical tools or engraving deep textures on molds, choosing the right galvo scanning system—2D or 3D—can significantly enhance productivity and engraving quality.
What is a Galvo Scanner?
A Galvo Scanner (Galvanometer Scanner) is an optical device that uses high-speed, precision-controlled mirrors to direct laser beams across the working surface. These mirrors are driven by galvanometer motors, which are known for their rapid response times and positioning accuracy.
Galvo scanners are essential in:
Laser marking
Laser welding
Laser cutting
Additive manufacturing
3D printing
PCB laser drilling
2D Galvo Scanner – The Industry Standard
The 2D Galvo Scanner is the most commonly used type in industrial laser applications. It works on two axes—X and Y—allowing the laser beam to move in a flat plane.
Key Benefits:
Ultra-fast marking speeds (up to 10,000 mm/s or more)
Stable performance for long-time operation
Excellent for flat surface engraving
Compatible with fiber, CO₂, and UV laser sources
Widely used in nameplate marking, barcodes, serial numbers, and QR codes
A 2D galvo scanner is ideal for users who need precise and efficient performance on flat materials like metals, plastics, ceramics, and more.
3D Galvo Scanner – Going Beyond Flat Surfaces
The 3D Galvo Scanner introduces an additional Z-axis for depth and focus control, making it possible to mark or engrave curved, uneven, or multi-level surfaces.
Advantages of 3D Galvo Scanners:
Dynamic focus for marking on irregular surfaces
Perfect for deep engraving or 3D texture creation
Adjustable focal length for variable-height products
Supports large-format engraving with focus compensation
Ideal for auto parts, molds, and decorative pieces
3D systems are commonly used in industries requiring complex and dynamic laser processing, such as aerospace, medical, and mold manufacturing.
Choosing Between 2D and 3D Galvo Scanners
| Feature | 2D Galvo Scanner | 3D Galvo Scanner |
|---|---|---|
| Axis Support | X and Y | X, Y, and Z |
| Surface Compatibility | Flat | Flat + Curved/Uneven |
| Cost | Lower | Higher (but more versatile) |
| Applications | Simple marking | Deep engraving, 3D designs |
If your production primarily involves flat materials, a 2D Galvo Scanner will meet your needs efficiently. However, for advanced applications requiring variable heights or detailed depth, the 3D Galvo Scanner is the superior choice.
Applications of Galvo Scanning Systems
Electronics: PCB marking, IC engraving
Jewelry: High-precision branding and serializing
Medical: Tool marking with UDI compliance
Automotive: Part identification and decoration
Packaging: Expiry dates, barcodes, and logos
