Abstract:
The invention relates to the use of a cleaning composition for removing uncured printing resin from 3D-printed articles, the cleaning composition comprising either of the following components alone or in combination: di basic esters of a carboxylic acid, tri basic esters of a carboxylic acid. The invention also relates to a process of cleaning a 3D-printed article, the process comprising the steps of a) providing the cleaning composition and a 3D-printed article comprising uncured printing resin on its surface, b) treating the surface of the 3D-printed article with the cleaning composition, c) optionally treating the 3D article with a solvent, in particular water, d) optionally drying the 3D article, optionally repeating steps b), c) and d) either singly or in combination. A further embodiment of the invention is directed to kit of parts comprising the cleaning composition and a 3D-printable resin composition, as well as a 3D-printing system comprising the cleaning composition, a 3D-printing device and a 3D-printable resin composition.
