Abstract
An additive manufacturing apparatus including a platform and a dispenser configured to deliver successive layers of feed material onto the platform. One or more light sources generate multiple light beams to selectively fuse feed material in a layer on the platform and multiple optical assemblies receive the multiple light beams, where each respective optical assembly transmits a respective light beam along a respective optical path through the optical assembly. Each light beam is directed to a scan spot on the layer of feed material on the platform to scan the light beam to sweep the scan spot along a controllable path across the layer of feed material on the platform. An optical multiplexer selectively transmits the return light emitted or reflected from the respective scan spot from a respective optical path of a selected respective optical assembly of the multiple optical assemblies to the measurement device.
