A synchronized concrete and bonding agent deposition system is proposed to address the weak interlayer bond strength issue in extrusion-based 3D concrete printing (3DCP). In the proposed system, printable concrete and bonding agent are deposited concurrently via a rotatable nozzle with two outlets....
