A New Era of Marking—3D Curved Surface Marking

The advent of 3D laser marking machines represents a major leap forward in laser marking technology. It no longer restricts processing to flat surfaces but extends to three-dimensional surfaces, enabling efficient laser engraving and micro-structuring on curved objects. Compared to traditional 2D laser marking machines, 3D laser marking machines offer the following advantages:

1.  Wider range and finer optical effects.

3D marking can be categorized into front-focus and rear-focus modes. In front-focus mode, the primary objective is to achieve a larger marking area. This typically employs larger deflection mirrors for the X and Y axes, allowing for a larger incident laser spot size while producing a smaller focused spot with higher energy density. This configuration satisfies the requirements for marking larger regions.

2. Variable focal length for three-dimensional marking.

Since 3D marking can rapidly adjust laser focal length and beam position, it enables surface marking on curved surfaces previously impossible with 2D methods. With 3D marking, cylindrical surfaces within the projection range can be marked in a single pass, significantly boosting processing efficiency. Furthermore, many industrial components feature non-planar surface geometries that 2D marking simply cannot handle—scenarios where 3D marking proves far more feasible.

3. Superior for Deep Engraving.

Traditional 2D marking inherently struggles with deep engraving on object surfaces. As the laser focus shifts upward during engraving, the energy reaching the actual surface drops sharply, severely compromising both engraving quality and efficiency. 3D marking eliminates these issues for deep engraving, ensuring both superior results and enhanced productivity.

3D laser marking machines broaden the technical application scope of laser marking and expand the demand for curved surface marking. During operation, the laser generates heat, necessitating a chiller for water circulation cooling to ensure the laser's normal functioning.
