3D Laser Marking Machine Also called 3D Laser cutter Machine.3D relief Machine.3D Laser Machine 

3D laser engraving is a laser surface depression processing method.

Compared with traditional 2D laser engraving, 3D engraving has greatly reduced the surface flatness requirements of the processed object, and the processing effects are more colorful and more creative. 

The processing technology came into being. 3D laser engraving technology is developing vigorously and has received a lot of attention in the industry. 

Some forward-looking industry companies are also stepping up the research and development of 3D laser engraving marking products; 

in the next few years, laser marking will gradually change from 2D Transition to 3D, 3D laser marking will penetrate into all areas of people's lives. 

1. The principle of 3D laser engraving/Marking Machine

A high-energy density laser is used to locally irradiate the workpiece to vaporize the surface material or cause a chemical reaction of color change, thereby leaving a 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 microns. The laser beam used for laser marking is generated by a laser. After a series of optical transmission and processing, the beam is focused by optical lenses, and then the focused high-energy beam is deflected to the specified position on the surface of the object to be processed, forming a trace of depression. Traditional 2D laser marking uses a rear focus method, and generally can only perform flat marking within a specified range. 

Application of 3D laser engraving/ marking industry

1)Large-scale engraving.

3D engraving Machine adopts the front focus optical mode, using larger X and Y axis deflection lenses, so it can allow the laser spot to be transmitted larger, the focusing accuracy is better, and the energy effect is better; if the 3D engraving is in the same way as the 2D engraving When working with the same focus accuracy, the engraving range can be larger.

As long as the shape of the workpiece is set in advance, only switching settings can correspond to the focal length, marking position and shape changes of different product positions. It can be completed without moving the workpiece multiple times or laser marking.


2)Deep engraving

Traditional 2D engraving Machine 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. 

For the traditional deep engraving method, the lifting platform is moved to a certain height at regular intervals during the engraving process to ensure that the laser surface is well focused. 3D engraving for deep engraving 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 table.


The 2D engraving Machine mode, the workpiece must be placed on the same plane, and the roughing surface must also be on the same plane, in order to achieve one-time marking. Using the characteristics of the 3D laser engraving machine, it is possible to achieve one-time marking when the workpiece has a high drop. Even on an oblique slope, the processing consistency can be maintained, so that the processing content is not deformed or not. Form a color difference. It greatly facilitates the engraving of the three-dimensional structure of the workpiece, reduces the process procedures, and improves the efficiency of marking.


Because 3D engraving  can quickly change the laser focal length and laser beam position, it becomes possible to mark curved surfaces that cannot be achieved in 2D in the past. 

After using 3D, the marking of cylinders within a certain arc can be completed at one time, which greatly improves the processing efficiency.

Furthermore, in real life, the surface shapes of many parts are irregular, and some parts have large differences in surface height. There is really nothing that can be done for 2D marking. At this time, the advantages of 3D marking will become more obvious.


In the same plane, black and white marking can be achieved, and even multi-color marking can be achieved with richer effects. For metal surface Make Black, such as anodized aluminum, it is usually done with higher frequency pulses under suitable energy and marking with a fixed defocus. The defocus distance obviously affects the laser’s surface on the material surface. Energy distribution and color effects. For ordinary 2D marking users, even if there is no need for curved surface marking and other features, it is very meaningful that the 3D marking machine can perform flat processing with multi-gray-scale and multi-color effects.

3D laser engraving machine is a special laser machine which engraving embossing effect on metal products, except 3d embossing function, also this 3D laser engraving machine can do engraving on Irregular surface, like round surface, cylinder surface, Bevel surface engraving, you can see some video in the above video, more function you can ask with our salesman, or send email to  

BOGONG MACHINERY also has other laser marking machine, like 2D Laser machine, MOPA laser engraving machine. also, we have co2 laser marking machine and UV laser marking machine.
