METHOD FOR TREATING AT LEAST ONE PORTION OF THE SURFACE OF A 3D PRINTED OBJECT

A method of treating at least part of a surface (110) of an article (100) in which an article (100) is treated, at least part of a surface (110, 111) of the article having been produced by an additive manufacturing method from a construction material, and the construction material provides a tempera...

Beschreibung
Zusammenfassung:	A method of treating at least part of a surface (110) of an article (100) in which an article (100) is treated, at least part of a surface (110, 111) of the article having been produced by an additive manufacturing method from a construction material, and the construction material provides a temperature TG′ at which the storage modulus G′ of the construction material (determined by dynamic-mechanical analysis according to ISO 6721 at a shear rate of 1/s) is 10 MPa. The article is preferably placed into an evacuable volume and the volume is evacuated. By heating and exerting pressure, the surface is plastically deformed and can be smoothed thereby.
