Beschreibung
Zusammenfassung:	An additive manufacturing apparatus includes a platform, a dispenser configured to deliver a plurality of successive layers of feed material onto the platform, a light source assembly to generate a first light beam and a second light beam, a beam combiner configured to combine the first light beam and the second light beam into a common light beam, and a mirror scanner configured to direct the common light beam towards the platform to deliver energy along a scan path on an outermost layer of feed material.
