Abstract
An additive manufacturing apparatus for building objects by layerwise consolidation of material. The apparatus includes a build chamber containing a working area, a high energy beam for consolidating material deposited in the working area in layers and a flow device for generating a gas flow across at least a part of the working area from a gas inlet to a gas outlet. The gas inlet and gas outlet are arranged to be movable within the build chamber.
