3D concrete printing (3DCP) has all the chances to become the future of the construction industry, but this technology is not yet widely applicable. One of the main challenges still to be mastered is the difficulty of reinforcing printed structures. At this point, many reinforcement strategies have already been proposed, which are fully or partially capable of solving the problem. This publication provides first an overview of existing reinforcement strategies, classified according to the time of reinforcement introduction: before, during, or after 3D printing. Then the authors present the approaches developed at TU Dresden and provide readers with information on new methods that still are in the development stage.
