3D laser marking is a laser surface concave processing method, compared with the traditional 2D laser marking, 3D marking on the processing of the object surface flatness requirements have been greatly reduced, in the process of deep carving, not only to ensure the effect, but also to enhance the efficiency of the processing of the effect of more colourful and more creative processing process came into being. 3D curved surface laser marking machine came into being, and gained continuous maturity and Development. With the progress of the times, the market demand for continuous updating, 3D surface laser marking machine can be in a variety of complex curved surface workpiece accurate and rapid marking, for the refinement of the surface of the marking enterprise to provide a more perfect processing scheme.
Nowadays, 3D laser marking adopts a front-focusing optical mode, using a large X\Y axis deflection lens. This facilitates the conduction of a larger laser spot, which improves the focusing accuracy and marks a larger surface. At the same time, 3D marking will not be like 2D, as the laser focal length of the upward shift, and affect the energy of the surface of the processed items, ultimately leading to unsatisfactory engraving results, the use of 3D marking, for a certain magnitude of the curved surfaces can be completed at once by using the current 3D laser marking. This greatly improves the processing efficiency.
In the current processing and manufacturing, there are many irregularly shaped products, some products will exist on the surface of the phenomenon of unevenness, and the traditional 2D marking method is unable to meet the demand, only the current 3D can be processed to complete. Although the laser marking machine is now widely used in many fields, but the emergence of 3D laser marking machine effectively fill the lack of laser curved surface processing, for the application of laser now provides a bigger stage.
