An additive manufacturing apparatus comprises a processing chamber defining a window for receiving a laser beam and an optical module. The optical module is removably-mountable to the processing chamber for delivering the laser beam through the window. The optical module contains optical components for focusing and steering the laser beam and a controlled atmosphere can be maintained within the module.
