3D UV Laser Marking Machine

The 3D UV Laser Marking Machine is capable of creating three-dimensional, depth-enhanced patterns and text on object surfaces. By combining a rotary device with 3-axis laser engraving technology, unparalleled three-dimensional effects can be achieved. This combination utilizes the laser’s ability to move in three directions, while the rotary device allows the workpiece to rotate in another dimension. This synergy enables precise laser engraving throughout the entire three-dimensional space.

The emergence of 3D laser marking machines marks a significant advancement in the field of laser marking. It removes the limitation of surface shapes being confined to a flat plane, expanding the capability to mark on three-dimensional surfaces efficiently. This advancement facilitates laser marking and surface microstructure manufacturing on three-dimensional curved objects with high efficiency.

3d uv laser marking machine

3D dynamic focus UV laser marking machine is an advanced tool used for precision marking on various materials. Unlike traditional laser marking machines, this machine utilizes UV (Ultraviolet) laser technology, which offers very fine details and high-resolution marks, making it suitable for applications where precision is crucial, such as LCD liquid crystal glass, medical devices, and electronic component.

The 3D Dynamic Focus features can adjust the focal point of the laser beam dynamically, allowing it to adapt to the contours and shapes of the material being marked. This capability enables the machine to produce consistent, high-quality marks even on uneven or curved surfaces.

This desktop UV laser marking machine adopts advanced digital 3-axis dynamic focusing technology with fast marking speed, as well as 3D curved surface stereo marking and large format marking functions. It is mainly applied to the marking needs of circular and curved objects such as LED bulbs, water bottles, mugs and eggs.

  • The UV laser has a shorter wavelength and a smaller focusing spot, which can realize ultra-fine marking effect. The use of high-speed digital vibrating mirror, marking speed, high efficiency and high precision.
  • The UV laser marking machine can not only mark on the plane, but also realize three-dimensional curved surface three-dimensional marking, making the marking effect more rich and diverse. It can accurately focus the spot within the height range of 0 to 150 mm to ensure the consistency of the marking effect.
  • The use of advanced digital three-axis dynamic focusing technology improves the marking speed, and zoom control is more real-time, while ensuring the uniformity of the focusing spot, thus improving the quality and efficiency of marking.

Key Features of 3D UV Laser Marking Machine

Variable Focus to Achieve Three-Dimensional Marking

3D marking technology with variable focal length function, can realize the complex three-dimensional surface for accurate marking, breaking through the limitations of 2D marking cannot deal with curved surfaces, especially for cylinders and other non-planar objects, you can one-time completion of the entire marking process, significantly improve work efficiency.

More Suitable for Deep Engraving

Compared with the traditional 2D marking, in the deep carving application, 3D marking has more advantages. 2D marking in the depth of the carving, with the laser focus upward, the energy attenuation is serious, affecting the effect of carving and speed. While 3D marking without the use of motorized elevator to adjust the focus, to maintain a good focus state, both to enhance the quality and efficiency of deep engraving, but also to reduce costs.

Larger Range and Finer Engraving

3D marking through the front focus and back focus mode, not only to achieve a large area marking, but also to achieve a finer engraving effect. In the front focus mode, the equipment uses a large-size deflector lens, which makes the laser spot focus smaller and has higher energy density to meet the demand for high-precision marking over a large area.

Rich Black White and Color Marking Effects

3D marking technology can also achieve rich black and white and color marking effects. For example, in the anodized aluminum surface marking black, through the regulation of laser frequency, focus distance and other factors, can create a variety of colors and grayscale effects. Even on occasions where curved surface marking is not required, 3D marking machines can also provide more detailed and rich color performance for 2D flat marking.
