3D laser marking

3D laser marking is a laser surface depression processing method, such as curved surface marking, three-dimensional engraving and deep engraving, etc. Compared with traditional 2D laser marking, 3D marking has greatly reduced the surface flatness requirements of processed objects, and can be processed. The effect is richer, and more creative processing technology emerges as the times require. 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 also gradually emerging. Compared with the previous 2D laser marking, the 3D laser marking can perform fast laser marking on products with uneven surfaces and irregular shapes, which not only improves the processing efficiency, but also meets the current personalized processing needs. Now processing and producing rich display styles, it provides more creative processing technology for current material processing. In recent years, with the gradual expansion of the market’s demand for 3D marking business, the current 3D laser marking technology has also attracted the attention of many companies in the industry. Some leading domestic laser companies have developed their own 3D laser marking machines, such as Han’s laser and Dowin laser, the 3D laser marking machine developed by Dowin laser is widely used in many industries, and the refined surface marking provides a professional solution for the current processing and production of surface 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, the 3D marking will not move up with the focal length of the laser like the 2D laser marking, which will affect the energy of the surface of the processed object, 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 the current processing and manufacturing, in order to meet specific needs, there are many products with irregular shapes, and some products may have irregularities on the surface. It seems that the traditional 2D marking method is limited and powerless. 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 shortcomings of laser surface processing and provided a broader stage for current laser applications.

So normal 2D fiber laser marking machine could not be used as a 3D marking machine by only using 3D software, it must use 3D scanner or 2.5D which use 3D software and an electrical up-down head. Dowin laser focus on laser technology since 2010, could offer you professional solution about laser technology.
