(57) The invention relates to a method for obtaining a concrete construction element (1) by additive manufacturing, in which superposed mortar layers are successively deposited so as to form two walls (2, 4), opposite one another, so as to form a cavity (3), as well as a plurality of reinforcement elements (21, 41, 22, 42) each extending from one of the walls (2, 4) towards the cavity (3), each reinforcement element (21, 41, 22, 42) being in contact with neither the wall (2, 4) opposite to that from which it extends, nor with a reinforcement element (21, 41, 22, 42) extending from the opposite wall (2, 4) to that from which it extends.
