OPTICAL ASSEMBLY FOR ADDITIVE MANUFACTURING

Abstract:

An additive manufacturing apparatus includes a platform, a dispenser to deliver a layers of feed material onto the platform, one or more light sources to generate a first light beam and a plurality of second light beams, a galvo mirror scanner to scan the first light beam on a layer of feed material on the platform, and a plurality of polygon mirror scanners. The galvo mirror scanner has a first field of view that spans a width of a build area of the platform, whereas, each of the plurality of polygon mirror scanners having a second field of view with the plurality of polygon mirror scanners providing a plurality of second fields of view. Each second field of view is a portion of the first field of view, and the plurality of polygon mirror scanners are positioned such that the plurality of second fields of view span the width of the build area of the platform.
