How Does 3D Laser Cutting Work?

3D laser cutting employs a computerized system that directs a laser beam along predefined paths on a workpiece. The laser beam is typically generated by a fiber laser or a CO2 laser, which emits a high-energy, concentrated beam of light. As the laser beam interacts with the material, it transfers thermal energy, causing the material to melt, vaporize, or burn.
