Abstract
A process can be used for the surface treatment of three-dimensional objects which have been produced in additive manufacturing processes from at least one polymer. The process involves a) immersing the three-dimensional object in a substance mixture A, b) leaving the three-dimensional object in the substance mixture A for a time, and c) removing the three-dimensional object from the substance mixture A. The process then involves d) immersing the three-dimensional object in a substance mixture B, e) leaving the three-dimensional object in the substance mixture B for a time, and f) removing the three-dimensional object from the substance mixture B. The substance mixture A has a temperature (process temperature A) which is above the melting point of the polymer, and the substance mixture B has a temperature (process temperature B) which is below the melting point of the polymer.
