The invention relates to a cleaning system for cleaning at least one three-dimensional object which is formed by solidification, in particular layer by layer or continuously, of a material which is solidifiable under the action of radiation, which cleaning system comprises a cleaning chamber for receiving the at least one three-dimensional object to be cleaned, wherein the cleaning system comprises at least one cleaning agent container containing uncontaminated cleaning agent, wherein the cleaning chamber and the at least one cleaning agent container are fluidically connected to one another, wherein the cleaning system comprises at least one conveying device for conveying uncontaminated cleaning agent from the at least one cleaning agent container into the cleaning chamber and for conveying contaminated cleaning agent from the cleaning chamber back into the at least one cleaning agent container. A method for cleaning at least one three-dimensional object is also proposed.

The invention is generally a system for drying, recycling, and washing off residual resin from three-dimensionally (3D) printed objects. Exemplary systems may include a wash reservoir, a fan module, and one or more air exchange vents. The wash reservoir contains a wash solvent and a propeller fully or partially submerged into the wash solvent. The propeller splashes the wash solvent upwards to disperse on the 3D printed object, thereby largely washing away the resin residue present in the 3D printer object. The fan module is connected to the wash reservoir to create a positive or negative air pressure inside the wash reservoir, thereby redirecting the airflow to the wash reservoir. The air exchange vents are provided between a splash guard and a platform/lid of the wash reservoir to act as an air intake when the fan module blows air out of the wash reservoir and as an exhaust vice versa.

The invention relates to: an apparatus (1) for the post-cleaning of 3D objects (90), 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 (1) comprises a cleaning chamber (2), which can be filled with a liquid cleaning agent (20) and has an agitator (5), for receiving the 3D object (90) to be cleaned, wherein a contamination detector (8), which is connected to a control unit (11) and determines the optical density of the cleaning agent (20), is provided for checking the remaining cleaning capacity of the cleaning agent (20), wherein the contamination detector (8) is located in an area kept free of non-translucent and insoluble particles above a predefined size in the cleaning agent (20). The determined optical density is used to determine the cleaning capacity of the cleaning agent (20).
