Abstract: The invention relates to a method for the post-treatment of 3D objects (10) printed from a light-curing resin formulation. A 3D object (10) removed from a 3D printer is post-treated according to the following steps: a) exposing the surface (11) of the 3D object (10) to a post-treatment liquid (16) comprising a light-curing resin formulation for a prescribed exposure time, wherein the post-treatment liquid (16) and the exposure time are chosen such that the post-treatment liquid (16) can penetrate into a crack (12) or a pore (13) on the surface (11) of the 3D object within the exposure time as a result of capillarity; b) removing the post-treatment liquid (16) remaining on the surface of the 3D object (10); and c) irradiating the 3D object (10) with light for post-curing the light-curing resin formulation used for the printing of the 3D object (10) and curing the post-treatment liquid (16) that has penetrated into cracks (12) and/or pores (13) on the surface (11) of the 3D object (10).
