Title: METHOD FOR TREATING AT LEAST PART OF THE SURFACE OF A 3D-PRINTED OBJECT
Abstract:
The invention relates to a method for treating at least part of a surface (110) of an object (100), in which an object (100) is treated, at least part of a surface (110, 111) of the object having been produced by an additive manufacturing method from a structural material, and the structural material having a temperature TG' at which the storage modulus G' of the structural material (determined by dynamically mechanical analysis according to ISO 6721 at an angular frequency of 1/s) is 10 MPa. The object is preferably placed in an evacuable space and the space is evacuated. By heating and exerting pressure, the surface is plastically deformed and can thereby be smoothed.
