Abstract: An additive manufacturing (AM) apparatus includes a build chamber, a build platform disposed within the build chamber for supporting an AM build part therein, and a build material deposition device. The apparatus further includes an energization arrangement having at least one energization source. The energization arrangement is capable of, in a fusion energy operation, selectively applying energy to a layer of build material to fuse the build material to form a next-to-be-produced layer of the AM build part and, in a material processing operation, selectively applying energy to and processing the surface of a last-produced layer of the AM build part, the layer of build material, and/or a surface of the next-to-be-produced layer.
