What are the specific advantages of the 3D laser marking machine?
First, a larger range and more elaborate light effects
3D marking uses a front focusing optical mode that uses a larger X, Y axis to deflect the lens. Thus allowing for a larger laser spot, better focusing accuracy, and better energy efficiency; if 3D marking is in 2D marking When working with the same focus accuracy, the marking range can be larger.
Second, can mark objects of different heights
3D marking can quickly change the laser focal length and laser beam position, making surface marking impossible for 2D possible. After using 3D, the cylindrical marking in a certain arc can be complete at one time. Which greatly improves the processing efficiency. Moreover, in real life, the surface shape of many parts is irregular. And the advantages of 3D marking will be very obvious.
Third, more suitable for deep carving
The traditional 2D marking has inherent defects in the deep surface carving of the object. 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 the deep carving.
The traditional deep carving method is to electrically move the lifting table at a certain height during the engraving process to ensure that the laser surface is well focused. The 3D marking for deep carving processing does not have the above problems, which not only ensures the effect, but also improves the efficiency, and at the same time saves the cost of the electric lifting platform.
Fourth, can achieve multi-color marking
For general metal surface blackening, such as anodized aluminum, it is usually using for a suitable energy to use higher frequency pulses, marking with a certain defocusing, the defocusing distance obviously affects the energy distribution of the laser on the material surface and Color effect. For general 2D marking users, even if advanced features such as surface marking are not required, it is meaningful for the 3D marking machine to perform plane processing of multi-gradation multi-color effects.
Compared to traditional flat marking, 3D laser marking machine has more practicality in many occasions. If you need deep surface carving, please choose 3D laser marking machine using laser beyond.
