3D laser marking technology is specifically designed for complex shapes, making it easy to mark curved, slanted, and cylindrical surfaces that are challenging for traditional 2D marking methods. By intelligently adapting to the geometric curvature of the workpiece, it delivers high-precision, detailed, and durable markings. Compared to conventional approaches like manual repositioning or using rotary axes, an industrial 3D laser marking system offers advanced dynamic focusing and spatial positioning capabilities, making it a key technology in driving production upgrades across industries such as mechanical manufacturing, automotive manufacturing and medical device fabrication.
How Does a 3D Fiber Laser Marking Machine Work?
A 3D laser marking machine operates by generating a high-energy laser beam through laser excitation. This beam is transmitted and modulated via an optical system, and finally, focused precisely onto the surface of the workpiece using optical lenses to perform marking. The focused high-energy laser ablates the surface of the material, leaving a permanent mark.
Traditional 2D laser marking is limited to flat or slightly curved surfaces and has a restricted marking range. In contrast, 3D laser marking uses software-controlled dynamic Z-axis and XY-axis galvanometers to precisely position and adjust the laser focus in three-dimensional space in real time. The system is equipped with a dynamic focusing lens capable of zooming and beam expansion, allowing the laser to maintain optimal focus on surfaces at varying heights. This enables high-precision marking on complex three-dimensional structures.
