    Abstract: Techniques for additive construction of structures and production of additive construction materials are described, including a 3D printing assembly including a container configured to store a material, a mixer configured to mix the material to provide an extrudable mix including cementitious material, and a dispenser configured to receive the flowable mix from the mixer and to provide the flowable mix under one or more controlled parameters to form a structure, and a controller configured to receive a value associated with a material property parameter of the material, to generate a mixture by inputting the value into a machine learning algorithm, the mixture being generated using, by the controller, another value associated with a control parameter configured to control operation of the 3D printing assembly, and using the 3D printing assembly to print a structure using the mixture.

    Abstract: Techniques for and examples of wall structures formed of extrudable building material (i.e., extrudable material) include a first shell having a first group of stacked elongated beads of extruded material that forms a first wythe, the first shell forming a first surface of the load-bearing wall structure, a second shell spaced apart from the first shell, the second shell having a second group of stacked elongated beads of extruded material that forms at least two second wythes, the at least two second wythes forming a second surface of the load-bearing wall structure, and at least one structural support that has a first portion embedded in the first shell and a second portion embedded in the second shell.

    Abstract: Construction systems for constructing a structure on a foundation and methods relating thereto are disclosed. In an embodiment, the construction system includes a rail assembly configured to be mounted to the foundation. In addition, the construction system includes a gantry movably disposed on the rail assembly configured to translate along a first axis relative to the rail assembly. Further, the construction system includes a printing assembly movably disposed on the gantry and configured to translate along a second axis relative to the gantry. The second axis is orthogonal to the first axis. The printing assembly is configured to deposit vertically stacked layers of an extrudable building material on the foundation to construct the structure. The gantry has a width along the second axis that is configured to be adjusted relative to the foundation.

    Abstract: A 3D printable clay-based mortar cementitious ink includes a blend of commercially available Type I/II Portland cement, and a fine and coarse silica sand. The ratio of Portland cement to fine sand or fine clay, may be approximately 1.02. The ratio of water-to-binder (Portland cement and SCM) may be approximately 0.55, and the ratio of water-to-powder (binder plus fine clay smaller than 75 microns) can be approximately 0.416. Included with the water and binder/powder mix is an admixture. According to one embodiment, the admixture can include a water reducing admixture, or plasticizer. The fine clay within the aggregate material is unprocessed, and the binder material is approximately 84 to 90 percent cement and 10 to 16 percent SCM. The unprocessed clay, or fine sand, does not undergo any heating, any chemical modification or sifting before being added to the aggregate material.

    Abstract: Embodiments disclosed herein relate to methods of constructing a structure and related non-transitory computer readable medium. In an embodiment, the method includes (a) defining a vertical first slice and a second vertical slice of the structure. A lateral cross-section of the structure within the first vertical slice is different than the lateral cross-section of the structure for the second vertical slice. In addition, the method includes (b) depositing a plurality of first vertically stacked layers of an extrudable building material with a printing assembly to form the first vertical slice. Further, the method includes depositing a plurality of second vertically stacked layers of the extrudable building material atop the first vertical slice with the printing assembly to form the second vertical slice.

    Abstract: Material delivery systems as well as systems and methods relating thereto are disclosed. In an embodiment, the material delivery system includes a tank to hold water therein. In addition, the material delivery system includes a hopper to hold dry ingredients of the extrudable building material therein. Further, the material delivery system includes a mixing unit to receive water from the tank and dry ingredients from the hopper. The mixing unit includes an agitator to mix the water and the dry ingredients together to form the extrudable building material. Still further, the material delivery system includes a controller coupled to the agitator that is to: measure a load imparted to the agitator by the extrudable building material, add additional water to the mixing unit when the load is above a first threshold, and add additional dry ingredients to the mixing unit when the load is below a second threshold.
