Abstract: The present invention enables real-time, automated monitoring and measurement of 3D printed concrete quality during an additive manufacturing process. The method continuously measures electrical impedance of the fresh concrete during the printing process, using electrodes automatically carried by the printing head at the same time as concrete printing proceeds. The real-time measured impedance, resistance, or capacitance curves as a function of printing time, printing path and printing location represent the fingerprint of the 3D printed concrete product being additively manufactured. The fingerprint contains essential information on the printing quality change with time and along the printing path, allowing the real-time detection of location and severity of imperfections. It also enables monitoring and quantifying concrete strength development during 3D printing. Furthermore, it allows closed-loop control to assure the printing quality through real-time adjustment and corrections of the printing parameters.
