Abstract

The invention relates to a method for producing a three-dimensional object, the outer surface of which has at least one surface section that is generated in that, by means of an additive production method (layer-building forming method), initially a surface section is produced on a flat base plate () in two-dimensional form, comprising the following steps: I) applying at least one curable polymer or curable reaction resin with a respective elastic modulus according to DIN 53504 (effective: 18 Apr. 2015) in the cured state, of <250 MPa in fluid form, as material webs onto a flat base plate () by means of a layer-building forming method in order to produce a first layer (); II) applying a second layer () onto the first layer () by means of the same or another layer-building forming method, like in step I); III) optionally applying between 1 and 48 additional layers according to step II), wherein each new layer is applied onto the respective previous layer; IV) curing the layers; V) releasing the cured surface section from the flat base plate (); VI) forming the cured surface section into a three-dimensional object; and VII) securing the three-dimensional object.
