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