A team of researchers from TU braunschweig in germany has developed a new method of 3D printing concrete that shows potential for more complex 3D printed structures. currently, 3D printed concrete construction focuses on three methods, material extrusion, particle-bed binding, and jetting, all of which apply the concrete in horizontal layers. unlike these layered techniques, injection 3D concrete printing (I3DCP) consists of robotically injecting a fluid material into another material with specific rheological properties, in other words, how the material responds under force or stress. free from gravity, injecting allows more complex structures to be printed in one piece.
