With the rapid development of laser technology, the processing form of laser is gradually changing. In order to meet the needs of curved surface processing, the current 3D laser marking technology is gradually emerging.
3D laser marking is a surface depression laser processing method. Compared with the previous 2D laser marking, 3D laser marking can perform fast laser marking on products with uneven surfaces and irregular shapes. It not only improves the efficiency of processing, but also meets the current personalized processing needs. It gives rich display styles for current marking for products, and provides more creative technology for current material processing.
The current 3D laser marking adopts the front focusing optical mode and uses a larger X, Y axis deflection lens. In this way, it is beneficial to transmit a larger laser spot, and the focusing accuracy and energy effect are greatly improved, and the marked surface is also larger.
At the same time, 3D marking will not affect the energy of the surface of the processed object as 2d laser marking does with the move up of the focal length of the laser, which will eventually lead to an unsatisfactory engraving effect. After using 3D marking, the current 3D laser marking can be used to complete the curved surface with a certain range at one time, which greatly improves the processing efficiency.
In today’s manufacturing, there are many products with irregular shapes in order to meet specific needs. Some products may still have irregularities on the surface. It seems that the traditional 2D marking method is limited and powerless. At this time, the current 3D laser marking can be used to complete the processing.
Although the fiber laser marking machine has been widely used in many fields, the emergence of 3D laser marking machine has effectively filled the shortcomings of laser curved surface processing and provided a broader stage for laser applications.
