The field of 3D concrete printing and the integration of load-bearing reinforcement remains a significant challenge. This paper introduces three innovative methods for constructing monolithic, steel-reinforced concrete walls using the CONPrint3D technology, which was previously developed for large-scale, monolithic, on-site 3D concrete printing. These methods include: 1) the additive application of reinforcement meshes hung in front of a printed core wall, 2) the lateral additive filling within a reinforcement cage, and 3) the fully automated construction of a welded reinforcement structure followed immediately by layer-by-layer encasement with extruded concrete. In the paper, the material challenges regarding concrete and the mechanical engineering development approaches are discussed. A comparative evaluation of these proposed and in lab scale tested new processes against established construction methods is included.
