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.

Abstract: A wall structure and a method for forming a wall structure is provided using three-dimensional printing of extruded building material applied to a surface of a building structure. According to one embodiment, the wall structure includes a pair of outer wythes spaced from an inner wythe. The outer wythes can include a core extending between the pair of outer wythes and toward the inner wythe. A protrusion can also extend toward the inner wythe a spaced distance from the inner wythe or entirely toward and adjoining the inner wythe. The core is configured with an inwardly facing spaced opposed surfaces of the outer wythes surrounding a vertically extending rebar, with grout surrounding that rebar. Horizontally extending support pins can be spaced parallel from each other and extend from the protrusions and into the inner wythe.
