3D laser marking industry application
1. Large-scale marking
3D marking adopts the front focusing optical mode, using larger X and Y axis deflection lenses, so it can allow the laser spot to be transmitted larger, the focusing accuracy is better, and the energy effect is better; if the 3D marking is in the same way as the 2D marking When working with the same focus accuracy, the marking range can be larger.
As long as the shape of the workpiece is set in advance, only switching settings can correspond to the focal length, marking position and shape changes of different product positions. It can be completed without moving the workpiece multiple times or laser marking.

2. Deep engraving
Traditional 2D marking has inherent defects in deep engraving of the object surface. As the laser focus moves up during the engraving process, the laser energy acting on the actual surface of the object will drop sharply, which seriously affects the effect and efficiency of deep engraving. For the traditional deep engraving method, the lifting table is moved to a certain height at regular intervals during the engraving process to ensure that the laser surface is well focused.
3. High and low surface marking
In the traditional 2D marking mode, the workpiece must be placed on the same plane, and the processing surface must also be on the same plane, in order to achieve one-step marking. Using the characteristics of the 3D laser marking machine, it can achieve one-time marking when the workpiece has a height difference. Even on an oblique slope, the consistency of the processing can be maintained, so that the processing content is not deformed and does not form a color difference. . It greatly facilitates the engraving of workpieces with three-dimensional structure, reduces the process steps, and improves the efficiency of marking.

4. Any surface marking
Because 3D marking can quickly change the laser focal length and laser beam position, it becomes possible to mark curved surfaces that cannot be achieved in 2D in the past. After using 3D, the marking of cylinders within a certain arc can be completed at one time, which greatly improves the processing efficiency. Furthermore, in real life, the surface shapes of many parts are irregular, and the height of some parts is quite different. There is really no way to do 2D marking. At this time, the advantages of 3D marking will become more obvious.

5. Color engraving
In the same plane, black and white marking can be achieved, and even multi-color marking can be achieved with richer effects. For general metal surface blackening, such as anodic aluminum oxide, higher frequency pulses are usually used under suitable energy, and marking is carried out with a certain defocus. The defocus distance obviously affects the energy distribution and energy distribution of the laser on the material surface. Color effect. For general 2D marking users, even if there is no need for advanced features such as curved surface marking, the 3D marking machine can perform flat processing with multi-gray and multi-color effects.
