3D Dynanic focus laser marking is a method of laser surface depression. Compared with traditional 2D laser marking, 3D marking has greatly reduced the surface flatness requirements of processing objects, and the effects of processing can be more colorful and more creative. Processing technology came into being. With the rapid development of laser technology, laser processing forms are gradually changing. In order to meet the demand for surface processing, 3D laser marking technology is now emerging. Compared with previous 2D laser marking, 3D laser marking can quickly laser mark products with uneven surface and irregular shape, which not only improves the processing efficiency, but also meets the current personalized processing requirements. Now it produces rich display patterns and provides more creative processing technology for material processing. In recent years, with the gradual expansion of market demand for 3D tagging services, the current 3D laser marking technology is also a concern of many companies in the industry. Some domestic leading laser companies have developed their own 3D laser marking machines, such as Chengdu MRJ- The 3D laser marking machine developed by laser is widely used in many industries nowadays. The refined surface marking provides a professional solution for processing and producing curved surface processing.
Today's 3D laser marking uses a pre-focusing optical mode, using larger X, Y-axis deflection lenses. This facilitates the conduction of a larger laser spot, which has a great improvement in focusing accuracy and energy effect, and the surface of the mark is also greater. At the same time, the 3D mark will not follow the upward movement of the laser focal length like the 2D laser mark, which will affect the energy of the surface of the processed object, and ultimately lead to an unsatisfactory engraving effect. After using 3D marks, surfaces with a certain amplitude can be completed at one time using current 3D laser marks, greatly improving the efficiency of processing. In current processing and manufacturing, due to the need to meet specific needs, there are many products with irregular shapes, and some products may have irregularities on the surface. The use of traditional 2D marking methods seems to be limited and it is necessary to use current 3D laser marking can complete the processing. Although the current fiber laser marking machine has been widely used in many fields, the emergence of 3D laser marking machine has effectively filled the gaps in laser surface processing and provided a broader stage for current laser applications.
