Abstract: Techniques for three dimensional printing of reinforced wall structures using extruded solidifiable material includes printing a first wythe that comprises a first plurality of stacked elongated beads of extruded material, printing a second wythe that comprises a second plurality of stacked elongated beads of extruded material, and building a porous layer disposed between the first wythe and the second wythe. In some examples, embedded reinforcement using mesh, wire, rebar, or other horizontally, diagonally, or vertically-emplaced members may also be performed, where the embedded reinforcement is placed between wythes or within (e.g., disposed within a bead of material, embedded reinforcement is placed) individual beads of a wythe.

Abstract: Techniques for and examples of a partition wall structure of a building are described, including a first shell formed as a first wythe including a first group of stacked elongated beads of extruded building material, a second shell spaced apart from the first shell and formed as a second wythe that has a second group of stacked elongated beads of extruded building material, and at least one structural support having a first portion embedded in the first wythe, and a second portion embedded in the second wythe.

Abstract: Techniques for and examples of wall structures of extrudable building material includes forming, with a three-dimensional (3D) printing system, a first portion of a first shell with a first wythe that comprises a first group of stacked elongated beads of an extrudable building material, forming with the 3D printing system a first portion of a second shell with a second wythe that comprises a second group of stacked elongated beads of the extrudable building material and is spaced apart from the first wythe, and installing at least one structural support that comprises a first portion positioned in the first wythe and a second portion positioned in the second wythe.

Abstract: Techniques of and examples for wall structures of extrudable building material include forming, with a three-dimensional (3D) printing system, a first portion of a first shell that includes a first plurality of stacked elongated beads of extruded building material that forms a first wythe, the first shell forming a first surface of the load-bearing wall structure, forming, with the 3D printing system, a first portion of a second shell spaced apart from the first shell, the second shell having a second plurality of stacked elongated beads of extruded building material that forms at least two second wythes, the second shell forming a second surface of the load-bearing wall structure, and installing at least one structural support that has a first portion positioned in the first shell and a second portion positioned in the second shell.
