Abstract: A system includes an optical device configured to emit light toward a build area, and an optical sensor configured to detect reflection of the light off the build area. The optical device operates at a first operating setting or at a second operating setting. The optical sensor receives reflection of the light emitted from the optical device operating at the first operating setting and reflected off the build area to determine one or more of a position, an orientation, or a shape of an object disposed on or within the build area. The optical device operates at the second operating setting to emit the light to additively form onto the object disposed on or within the build area.
