Abstract

An additive manufacturing apparatus comprises a laser beam source emitting a laser beam, a build platform, a powder source depositing a layer of powder onto the build platform, and a scanning assembly disposed along an optical path between the laser beam source and the build platform. The scanning assembly comprises at least one solid state optical deflector that modifies at least one of a size or an impingement location of the laser beam on the layer of powder at a scanning position of the laser beam. The at least one solid state optical deflector may be used to heat treat the layer of powder either before or after the powder is melted.
