Wall structures of extrudable building material

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.
