Abstract
An additive manufacturing method includes providing a first and second scanners with fields of view that at least partially overlap. The method includes applying a layer of powder-based materials to the part bed and providing a number of laser sources that direct a number of laser beams to the first and second scanners. The laser beams are directed from the scanners to the part bed to selectively fuse the material to produce a layer of a three-dimensional part. The layer is formed by selectively directing laser energy to the material in a selected pattern, and synchronizing the movement of the laser beams to continuously process the selected pattern in each layer of the three-dimensional part. An additive manufacturing system includes first and second laser sources, first and second scanners, and a controller configured to operate the scanners and laser(s) for producing the three-dimensional printed part.
