Claim 1:
2. The method of claim 1, wherein the printhead assembly comprises a printhead and defines a printhead axis which is parallel to the vertical axis, the printhead comprising a supply coupling, a deposition nozzle, and a translatable flow-directing element, the deposition nozzle defining a deposition orifice which circumscribes the printhead axis and is oriented orthogonal thereto, and wherein depositing one or more layers of the wall element further comprises:
receiving, via the supply coupling, a portion of a cementitious material from a material supply;
establishing a fixed print path for the printhead by aligning the printhead axis with the midline reference curve, wherein the printhead axis remains aligned with the midline reference curve and parallel with the vertical axis during the deposition of the cementitious material;
maintaining the deposition orifice in a fixed shape and orthogonal to the printhead axis during the deposition of the cementitious material; and
establishing a deposition footprint of the cementitious material at at least one radial position which is offset from the midline reference curve via the translatable flow-directing element positioned within the deposition nozzle between the supply coupling and the deposition orifice.
