Abstract: Disclosed is an apparatus for the additive manufacture of a component comprising a substantially annular bed for supporting the component, a powder depositor, an energy beam source for emitting a beam of energy towards a beam target location, and control means for adjusting the beam target location. The apparatus is configured to provide rotation of the beam target location and/or the powder depositor relative to the bed, the relative rotation being about a rotational axis. Also disclosed are a method for additive manufacture, a gas turbine engine, and an aircraft.
