2D Laser Marking Machine: Suitable for marking flat surfaces. Using XY-axis galvanometers to control the movement of the laser beam within a two-dimensional plane, it offers high marking accuracy (repeatability ≤ ±0.001mm) and is suitable for simple designs such as regular text and QR codes.
2.5D Laser Marking Machine: Supports both relief and deep engraving, using dynamic Z-axis focus to achieve localized depth variation. Suitable for textured engraving on metal and non-metal surfaces (such as molds and cutting tools).
3D Laser Marking Machine: Designed specifically for three-dimensional curved surfaces, it features a motorized lifting column and a 3D galvanometer (such as the FEELTEK F10). It automatically compensates for surface height differences and is suitable for marking complex curved surfaces such as automotive parts and aerospace components.
Decision Recommendations
Prioritize 2D: If you only need flat marking and have a limited budget, 2D models offer the best value.
Choose 2.5D: If you need relief effects but don't need surface adaptation, 2.5D is a good compromise.
Upgrade to 3D: When processing complex curved surfaces or high-precision industrial parts (such as aviation parts), 3D is irreplaceable.
