Abstract
An additive manufacturing system includes a plurality of laser devices, a plurality of first scanning devices, and an optical system. The optical system includes an optical detector and a second scanning device. The plurality of laser devices are each configured to generate a laser beam. The plurality of first scanning devices is each configured to selectively direct the laser beam from a laser device of the plurality of laser devices across a powder bed. The laser beam generates a melt pool in the powder bed. The optical detector is configured to detect electromagnetic radiation generated by the melt pool. The second scanning device is configured to direct electromagnetic radiation generated by the melt pool to the optical detector. The optical system is configured to detect a position of the laser beams in the melt pool.
