Abstract
The invention relates to: an apparatus () for the post-cleaning of 3D objects (), which are printed from a light-curing resin formulation and comprise uncured residues of the resin formulation which adhere to the surface and have non-translucent and insoluble particles; and the use of a corresponding apparatus. The apparatus () comprises a cleaning chamber (), which can be filled with a liquid cleaning agent () and has an agitator (), for receiving the 3D object () to be cleaned, wherein a contamination detector (), which is connected to a control unit () and determines the optical density of the cleaning agent (), is provided for checking the remaining cleaning capacity of the cleaning agent (), wherein the contamination detector () is located in an area kept free of non-translucent and insoluble particles above a predefined size in the cleaning agent (). The determined optical density is used to determine the cleaning capacity of the cleaning agent ().
