Abstract

The invention relates to a method for producing a three-dimensional target structure using a 3D printing device, comprising the following method steps: a) generating at least one three-dimensional support structure (10a-c) with the 3D printing device by outputting at least one first material; b) applying an adhesive to the partial section (12a-c) of the surface of the support structure (10a-c) in order to obtain a prepared support structure (14a-c) having a surface adhesive layer (16a-c); c) generating a three-dimensional target structure (18) by dispensing at least one second material with a 3D printing device, wherein the second material is at least partially applied to the adhesive layer (14a-c) of the prepared support structure (14a-c); and d) separating the support structure (10a-c) from the target structure (18) in the region of the adhesive layer (16a-c).
