A device suitable for cleaning a workpiece manufactured by means of additive manufacturing from a granular and/or powdery manufacturing material and/or suitable for removing excess granular and/or powdery manufacturing material after manufacturing the additive workpiece, wherein the device comprises a housing in which a workpiece holder is arranged, at or on which the manufactured workpiece can be arranged, at least one conveyor device is arranged in or on the housing for removing excess manufacturing material from the inside of the housing, and at least one moveable nozzle is arranged on at least one moveable nozzle arm in the inside of the housing so that at least one cleaning fluid flow can be applied to the workpiece and the inside of the housing during a cleaning cycle in which the workpiece and/or the inside of the housing are cleaned of excess manufacturing material, wherein, an angle is provided at the end of the nozzle arm, on which the moveable nozzle is arranged, at least one nozzle rotation is provided in which the nozzle can be rotated about at least one nozzle rotational axis relative to the nozzle arm, and at least one arm rotation is provided, in which the nozzle arm can be rotated around an arm rotational axis relative to the workpiece holder, wherein the rotation speed of the nozzle rotation and the speed of the arm movement are designed in such a way that, during a cleaning cycle, the cleaning fluid flow assumes all or almost all flow directions within the housing so that the entire or almost the entire surface of the workpiece and the housing can be directly affected by the cleaning flow from all or almost all directions, wherein the orientations of the nozzle rotational axis and the arm rotational axis differ, wherein the nozzle undergoes a multitude of revolutions per nozzle arm revolution, and wherein the workpiece holder inside the housing can be moved, or swivelled, or rotated, or moved and swivelled, or moved and rotated, or swivelled and rotated, or moved and swivelled and rotated, or could be moved and swivelled and rotated. the device comprises a housing in which a workpiece holder is arranged, at or on which the manufactured workpiece can be arranged, at least one conveyor device is arranged in or on the housing for removing excess manufacturing material from the inside of the housing, and at least one moveable nozzle is arranged on at least one moveable nozzle arm in the inside of the housing so that at least one cleaning fluid flow can be applied to the workpiece and the inside of the housing during a cleaning cycle in which the workpiece and/or the inside of the housing are cleaned of excess manufacturing material, wherein, an angle is provided at the end of the nozzle arm, on which the moveable nozzle is arranged, at least one nozzle rotation is provided in which the nozzle can be rotated about at least one nozzle rotational axis relative to the nozzle arm, and at least one arm rotation is provided, in which the nozzle arm can be rotated around an arm rotational axis relative to the workpiece holder, wherein the rotation speed of the nozzle rotation and the speed of the arm movement are designed in such a way that, during a cleaning cycle, the cleaning fluid flow assumes all or almost all flow directions within the housing so that the entire or almost the entire surface of the workpiece and the housing can be directly affected by the cleaning flow from all or almost all directions, wherein the orientations of the nozzle rotational axis and the arm rotational axis differ, wherein the nozzle undergoes a multitude of revolutions per nozzle arm revolution, and wherein the workpiece holder inside the housing can be moved, or swivelled, or rotated, or moved and swivelled, or moved and rotated, or swivelled and rotated, or moved and swivelled and rotated, or could be moved and swivelled and rotated.
