3D laser marking machine brings more creative designs to surface processing

With the rapid development of laser technology, the market has more and more demand for 3D marking business, and the processing form of laser is gradually changing. In order to meet the needs of surface processing, the current 3D laser marking technology is gradually emerging. The current 3D laser marking technology is also concerned by many companies in the industry. Some leading domestic laser companies have developed their own 3D laser marking machines, which are widely used in mobile phone manufacturing, three-dimensional circuits, medical equipment, molds, 3C electronics, and automotive parts. components, electronic communications and other industries. Refined surface markings provide a professional solution for surface machining today.

Key points: 3D laser marking improves efficiency and solves the engraving effect of 2D unevenness.

At present, Bot Laser's 3D laser marking machine adopts the front focusing optical mode and uses a large X, Y axis deflection lens. In this way, it is beneficial to transmit a larger laser spot, which greatly improves the focusing accuracy and energy effect, and the surface of the mark 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 a little powerless to use the traditional 2D marking method. 3D laser marking can complete the processing. Although the current fiber laser marking machine has been widely used in many fields, the emergence of the 3D laser marking machine has effectively filled the shortage of laser surface processing and provided a broader stage for the current laser application.

Extension: German researchers have developed a new process for laser processing curved glass

In the process of 3D glass hot bending, the flat glass is heated and softened to be stably formed in the mold, and then annealed to make curved glass. However, these molds are expensive to manufacture and the process is time-consuming. Now researchers at the Fraunhofer Institute for the Mechanics of Materials in Germany have developed an alternative laser-based technology that is less expensive and takes less time to process.

Because there is no support under the glass, the softened part begins to sink due to gravity. Once the desired shape is achieved, the laser is turned off, allowing the glass to cool and harden in the new form. It takes about half an hour for the glass to cool completely in the oven. That said, depending on the complexity of the design, the laser can do the job in minutes. This means that multiple glass sheets can be processed in a relatively short time.
