A cleaning device configured to clean three dimensional objects (7, 14) produced by layered application and selective solidification of a powdery building material wherein the three dimensional objects (7, 14) are cleared from a non-solidified powdery building material that envelops the objects (7, 14) and/or that remains in openings or channels of the objects (7, 14), the cleaning device comprising: a) a cleaning chamber in which an object (7, 14) is cleaned and that includes at least one outlet opening configured to release powder that has been cleaned from the object (7, 14) from the cleaning chamber wherein the cleaned off powder passes through the outlet opening, b) a pivot device on which the object (7, 14) is fixable and on which the object (7, 14) is pivotable relative to at least one pivot axis (11, 12) into various pivot positions, c) an electronic control device that controls or regulates the pivot device to control or regulate the pivot positions of the object (7, 14), characterized in that d) the cleaning device further comprises a sensor device which captures a cleaning variable that represents an amount, a mass, a mass flow, a volume and/or a volume flow of the powdery building material that is cleaned from the object (7, 14) and that passes the at least one outlet opening, e) wherein the electronic control device controls or regulates the pivot device so that pivot positions of the object (7, 14) are controlled or regulated as a function of the cleaning variable, wherein f) the electronic control device controls or regulates the pivot device during a subsequent cleaning process so that - the object (7, 14) is pivoted with respect to the at least one pivot axis (11, 12) into various pivot positions and so that the cleaning variable is captured by the sensor device, wherein a pivoting of the object (7, 14) is stopped in each pivot position of the different pivot positions in which the cleaning variable reaches or exceeds a predetermined minimum value for the cleaning variable, subsequently - wherein the object (7, 14) is stopped in a respective pivot position and the cleaning variable is captured until the cleaning variable has dropped below the predetermined minimum value, subsequently - wherein the object (7, 14) is pivoted into additional pivot positions, - wherein the pivoting of the object (7, 14) into the additional pivot positions and the cleaning process are terminated when the captured cleaning variable does not reach or exceed the predetermined minimum value for the cleaning variable in any of the pivot positions. a) a cleaning chamber in which an object (7, 14) is cleaned and that includes at least one outlet opening configured to release powder that has been cleaned from the object (7, 14) from the cleaning chamber wherein the cleaned off powder passes through the outlet opening, b) a pivot device on which the object (7, 14) is fixable and on which the object (7, 14) is pivotable relative to at least one pivot axis (11, 12) into various pivot positions, c) an electronic control device that controls or regulates the pivot device to control or regulate the pivot positions of the object (7, 14), characterized in that d) the cleaning device further comprises a sensor device which captures a cleaning variable that represents an amount, a mass, a mass flow, a volume and/or a volume flow of the powdery building material that is cleaned from the object (7, 14) and that passes the at least one outlet opening, e) wherein the electronic control device controls or regulates the pivot device so that pivot positions of the object (7, 14) are controlled or regulated as a function of the cleaning variable, wherein f) the electronic control device controls or regulates the pivot device during a subsequent cleaning process so that -

wherein the object (7, 14) is stopped in a respective pivot position and the cleaning variable is captured until the cleaning variable has dropped below the predetermined minimum value, subsequently - wherein the object (7, 14) is pivoted into additional pivot positions, - wherein the pivoting of the object (7, 14) into the additional pivot positions and the cleaning process are terminated when the captured cleaning variable does not reach or exceed the predetermined minimum value for the cleaning variable in any of the pivot positions. - the object (7, 14) is pivoted with respect to the at least one pivot axis (11, 12) into various pivot positions and so that the cleaning variable is captured by the sensor device, wherein a pivoting of the object (7, 14) is stopped in each pivot position of the different pivot positions in which the cleaning variable reaches or exceeds a predetermined minimum value for the cleaning variable, subsequently -
