▎ 摘　　要

NOVELTY - Treating a molded part comprises: (a) providing a molded part constructed from (a1) at least one polymer K and (a2) at least one material; (b) contacting the molded part with at least one solvent-A; and (c) forming a concentration gradient on the surface of the molded part with the concentration of the polymer K increasing towards the surface. USE - The molded part is useful as an element (claimed) for three dimensional printing. ADVANTAGE - The method is economical and enables faster processes due to faster energy input. The molded part restores the original or natural color tone without the additives that change the color.
