In recent years, the development of laser technology has made remarkable progress. Among them, the emergence of 3D laser marking machines is a major jump in the field of laser marking, which has broken through the limitation of the past limited to 2D flat marking and realized the marking of curved surfaces. Therefore, 3D laser marking machine is widely used in a variety of industries.

Applications of 3D laser marking machine

1. Automotive industry

3D laser marking is widely used in the automotive industry for various parts marking, including engine parts, chassis and electronic systems. 3D fiber laser marking can provide high security, traceability and durability, ensuring effective quality control and anti-counterfeiting.

2. Electronics industry

From circuit boards to microchips, 3D laser markers provide precise marking on a variety of electronic components. These markings help identify, track and read essential information such as serial numbers, manufacturing codes and brand logos.

3. Medical industry

3D laser marking also ensures the permanent identification of instruments, implants and surgical instruments in medical device manufacturing. These markings can include lot numbers, batch codes, and even patient-specific information, thus enhancing traceability and safety throughout the medical process.

4. Jewelry and fashion industry

3D laser marking enables customization and personalization for the jewelry and fashion industries. It allows intricate and precise marking on metals, gemstones and various accessories, thus adding value and uniqueness to products.

5. Aerospace industry

3D laser markers can also be widely used in the aerospace industry with precise marking results that meet strict quality and traceability standards. 3D laser marking can be applied to mark aircraft components, provide important identification information, prevent forgery and ensure operational safety etc.

Advantages of 3D laser marking machines

Compared with the traditional 2D laser marking technology, 3D laser marking breaks through the application limitations of curved surface marking, and has the following advantages:

1. Variable focal length to achieve 3D marking

3D marking can quickly adjust the laser focal length and laser beam position so that curved surface marking is possible.  For example, the cylindrical markings that required multiple markings in the past can now be completed at once, greatly improving processing efficiency, thus solving the problem of marking on carved surface shapes of parts that 2D marking cannot meet.

2. Larger range and finer light effect

3D marking can use both front-focus and back-focus modes. The front-focus mode can achieve a larger range of marking, allowing a larger laser spot to enter and achieve a higher energy density through a smaller focused spot to meet the requirements of a larger area marking.

3. More suitable for deep engraving

There are inherent defects in traditional 2D marking for deep engraving on the surface of objects. 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. However, 3D marking for deep carving processing does not have the above problems, which not only ensures the effect but also improves efficiency.
