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 beenproduced 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 bydynamically 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. 处理物件(100)的表面(110)的至少一部分的方法，其中处理物件(100)，其中所述物件的表面(110、111)的至少一部分由建造材料通过增材制造法制成，且其中所述建造材料具有温度T，在该温度下所述建造材料的储能模量G'（通过根据ISO 6721的动态-机械分析在1/s的角频率下测定）为10 MPa。优选将所述物件放入可抽真空的容积中并将所述容积抽真空。通过加热和施加压力，表面塑性变形并可由此变光滑。
