Abstract (en)

A method for producing a reinforced three-dimensional object from a binder composition with an additive manufacturing process, comprising the steps of:a) Applying a first curable binder composition in the setting state with an additive manufacturing device, especially having a movable printing head, to produce the three-dimensional object (UP);b) During and/or after producing the three-dimensional object (UP), forming at least one cavity (C) for receiving a reinforcement element (RB) in the three-dimensional object (UP);c) Insertion of a reinforcing element (RB) into the at least one cavity (C);d) Casting of the reinforcing element (RB) inside the at least one cavity (C) with a second curable binder composition (SL) in the setting state which is chemically and/or physically different from the first curable binder composition.
