Abstract
An additive manufacturing system includes a laser device, a build plate, a first scanning device, and an alignment system. The laser device is configured to generate a laser beam. The build plate has a position relative to the laser device. The first scanning device is configured to selectively direct the laser beam across the build plate. The laser beam generates a melt pool on the build plate. The alignment system includes a fiducial marks projector configured to project a plurality of fiducial marks across the build plate. Each fiducial mark has a location on the build plate. The alignment system also includes an optical detector configured to detect the location of each of the fiducial marks on the build plate. The alignment system is configured to detect the position of the build plate relative to the laser device.
