3D laser marking machine is an advanced laser marking equipment that can perform precise marking operations on three-dimensional surfaces. Compared with traditional flat laser marking machines, 3D laser marking machines have higher flexibility and can handle workpieces of various complex shapes and curved surfaces, such as metals, plastics, ceramics and other materials. The equipment uses high-speed and high-precision laser scanning technology to make the marking content clear, durable and have high visual effects. It is widely used in electronics, automobiles, aerospace, medical equipment and other industries to meet the diverse needs of identification, serial numbers, QR codes, etc. The emergence of 3D laser marking machines has greatly improved the personalization and traceability of products, and provided strong technical support for modern manufacturing.

The core difference between 3D marking machines and ordinary (traditional 2D) marking machines lies in their adaptability to the processed surface and their optical path control methods. This directly leads to significant differences in their application range, accuracy, and efficiency.

Core Differences: Processing Capability and Surface Adaptability

Ordinary 2D Marking Machines: Use a back-focusing method, with the laser focus fixed on a single plane. It can only mark on flat surfaces, requiring extremely high surface flatness. If the workpiece surface has curved, arc-shaped, spherical, or uneven surfaces, the 2D marking machine cannot effectively focus, resulting in blurry marks, inconsistent depth, or even failure to complete the marking.

3D Marking Machines: Use a front-focusing (or dynamic focusing) optical mode, equipped with a three-dimensional dynamic scanning galvanometer and a dynamic focusing mount. It can control the focal length of the laser beam in real time through software, automatically compensating for height differences on the workpiece surface. Therefore, it can perform one-time, high-precision marking on irregular, uneven surfaces such as curved surfaces, arc surfaces, spherical surfaces, deep engravings, and reliefs, greatly expanding the application range of laser marking.

Optical Path Control and Precision

Ordinary 2D Marking Machine: The optical path is relatively simple, focusing through a fixed field lens. Changing the scanning range (area) usually requires replacing the physical lens.

3D Marking Machine: By jointly controlling the galvanometers along the X, Y, and Z axes, the spot size and focal point position can be adjusted in real time during scanning. This ensures that the laser energy density remains consistent throughout the processing area, resulting in uniform and clear marking effects. Furthermore, its software-controlled area switching method is faster and more flexible than changing physical lenses.

Application Effect and Efficiency

Ordinary 2D Marking Machine: Suitable for simple and regular marking such as planar markings, barcodes, and serial numbers.

3D marking machines not only perform traditional marking but also deep engraving, relief marking, and multi-color marking (achieving black and white marking effects on the same plane), resulting in richer and more diverse marking effects to meet personalized and high-value-added processing needs. For complex curved workpieces, 3D marking machines can complete the processing in one pass, significantly improving efficiency and avoiding the need for multiple clamping operations or special tooling that may be required in traditional methods.

In summary, 3D marking machines are an advanced technology developed to overcome the limitations of 2D marking machines in curved surface processing. They possess unparalleled advantages in adapting to complex curved surfaces, achieving high-precision dynamic focusing, improving processing efficiency, and enriching marking effects.
