Beschreibung
Zusammenfassung:	This invention concerns an additive manufacturing apparatus for building objects by layerwise consolidation of material. The apparatus comprises a build chamber (101) containing a working area, a high energy beam (118) for consolidating material deposited in the working area in layers and a flow device (110, 112) for generating a gas flow across at least a part of the working area from a gas inlet (112a) to a gas outlet (110a). The gas inlet (112a) and gas outlet (110a) are arranged to be movable within the build chamber (101).
