Abstract
The invention relates to a device for cleaning a workpiece produced by means of additive production from a granular and/or powdery production material and/or for removing excess granular and/or powdery production material after additive workpiece production. The device comprises a housing in which a workpiece mounting is arranged on which or on which the produced workpiece can be arranged. In or on the housing at least one conveyor is arranged to convey, in particular, excess production material, away from the housing interior. At least one movable nozzle is arranged on at least one movable nozzle arm in the housing interior, such that the workpiece and the housing interior can be acted upon by at least one flow of the cleaning fluid during a cleaning cycle in which the workpiece and/or housing interior are purged of, in particular, excess production material. At least one nozzle rotation is provided, in which the nozzle can be rotated about at least one nozzle rotation axis relative to the nozzle arm. At least one arm trajectory movement and/or at least one arm rotation is provided, in which the nozzle arm can be moved and/or rotated relative to the workpiece mounting along at lea…
