In this thesis, a robust control system is developed to manipulate the width of the extruded concrete bead while printing. The system is designed to work with a printer that is intended for use in expeditionary, military environments. The system generates a process map that correlates the width of the extruded concrete bead to the velocity of the gantry printer. To accomplish this, a calibration print is designed that varies the gantry velocity along the print path and holds a constant pump speed. After the calibration print is printed, an advanced scanning apparatus is used to the measure the bead width along the entire print. A process map is then generated from the resulting measurements. From the process map, desired printing parameters are selected and input into the G-code to achieve the desired bead width. This method enables military operators to select multiple bead widths to be implemented in prints regardless of the rheological properties of the cement-based material that is being extruded. The end result of this robust control system is the ability to manipulate the bead width during large-scale additive construction prints to within ± 1/4”, on average.
