Laser engraving/marking machines come in two main types: flatbed lasers (laser plotters) and galvo lasers.
Flatbed System:
Laser plotters employ a gantry structure similar to traditional printers. The laser head is mounted on a movable arm system that enables two-dimensional processing across the material’s surface through coordinated X and Y axis movements. A focusing lens projects the beam vertically onto the workpiece. The effective processing area is directly proportional to the overall size of the equipment, with larger machines allowing larger-scale engraving operations.
Galvanometric System:
Galvo lasers utilize galvanometric scanning technology to direct the laser beam with high precision and speed. Instead of mechanical movement, high-speed oscillating mirrors (galvanometers) dynamically adjust the beam’s trajectory. The marking field is determined by the deflection angle of the optics and their focal length, enabling fast processing with millimeter-level accuracy.
Use this guide to decide which suits your needs.
Cutting Applications
Feature | Flatbed Laser | Galvo Laser |
Cut Edge Quality | Perpendicular beam ensures straight cuts (ideal for thick materials like acrylic, MDF, wood). | Angled beam causes visible edge slope on thicker materials. |
Speed | Slower but precise for large-area projects. | 10–65× faster for thin materials (paper, foil, laminates). |
Working Area
Feature | Flatbed Laser | Galvo Laser |
Size | Larger (up to 1800mmx1200mm) for big or multiple parts. | Smaller (30mm × 30mm to 1500mm × 1500mm) but expandable with attachments. |
Flexibility | Limited by machine size; ideal for bulk processing. | Handles bulky parts via adjustable housings or pass-throughs. |
Production Environment & Speed
Feature | Flatbed Laser | Galvo Laser |
Setup | Standalone operation; manual loading/unloading. | Modular: manual, semi-automated, or fully integrated with conveyors. |
Cycle Time | Slower for complex jobs; multi-machine operation. | Seconds-per-task; optimized for high-speed automation. |
Configurability
Feature | Flatbed Laser | Galvo Laser |
Adaptability | Quick lens/tabel adjustments for diverse tasks. | Tailored to specific applications (e.g., ERP integration, dynamic data marking). |
Laser source | Usually use Co2 glass tube 80W- 300W | Usually use Co2 RF metal tube 150W- 400W |
Key Takeaways
- Choose Flatbed Lasers for thick materials , large-scale products , or precise perpendicular cuts.
- Choose Galvo Lasers for speed, thin-material efficiency, and scalable automation.
