Sensor Fusion Enables Comprehensive Analysis of Laser Processing in Additive Manufacturing


New laser processes, such as additive manufacturing (AM) techniques using laser powder bed fusion (LBPF), require consistent energy be delivered to the metal powder material that is to be transformed. Successful outcomes require the power density distribution of the laser beam, as it is delivered to the weld plane, to be symmetrical, uniform, and stable. AM laser applications require the beam spot size and intensity to be maintained within a finite acceptance window. In most cases, laser parameters must be measured to be certain the requirement for consistent, stable, and correct laser power density or irradiance is met. But how do we know the laser is delivering exactly the beam that is needed?
