Characteristics and Application Advantages of 3D Laser Marking Machine

The emergence of 3D laser marking machine is a major leap in the field of laser marking. The surface shape of the processed object is no longer limited to the plane-like surface. It can be extended to three-dimensional surfaces to achieve high-efficiency laser graphics for three-dimensional curved objects. Marking and surface microstructure manufacturing.

The laser marking machine uses a high-energy density laser to locally irradiate the workpiece to vaporize the surface material or undergo a chemical reaction of color change, thereby leaving a permanent mark. Laser marking can mark a variety of characters, symbols and patterns, etc., and the size of the characters can even reach the order of micrometers.

So, what are the product characteristics and application advantages of 3D laser marking machine?

The laser marking machine automatically adjusts the laser focal length for three-dimensional curved objects to meet three-dimensional marking; it can meet the one-time marking of objects with different heights without multiple assembly and focusing; three-dimensional projection marking has no visible distortion; it can be right-angled Double-sided marking on the outside; support 3D DXF, STL file format; support relief processing; support 532nm, 1064nm, 10.6um multiple laser work.

1. Larger range and finer light effects

3D marking can be divided into two types: front focus and back focus. When the front focus mode is used, the main purpose is to achieve a larger marking range. Generally, a larger X, Y axis deflection lens is used to allow the incident laser spot to be larger. Larger, a smaller focused spot and higher energy density are obtained; thereby meeting the requirements of a larger area.

2. Variable focal length to realize three-dimensional marking

Since 3D marking can quickly change the laser focal length and the position of the laser beam, it becomes possible to mark curved surfaces that cannot be achieved in 2D in the past. After using 3D marking, the cylindrical marking in the light projection range can be completed at one time, which greatly improves the processing efficiency. Furthermore, the surface shape of many parts of industrial products is not only flat, and it is really powerless for 2D marking processing. At this time, 3D marking is easier to achieve.

3. More suitable for deep engraving

Traditional 2D marking has inherent defects in deep engraving of the object surface. 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 deep engraving. 3D marking for deep engraving processing does not have the above-mentioned problems, which not only guarantees the effect, but also improves the efficiency. The 3D laser marking machine has improved the scope of technical application for laser marking processing and expanded the demand for surface marking.
