3d printed earth-fiber structures

A method of making a structure, comprising:

• providing a mixture, comprising:
• an earth component;
• at least one fiber component;
• a fluid component;
• and
• at least one additive component;
• and,
• fabricating one or more structures from the mixture, the fabricating including a 3D printing process, a mechanical compression process, a manual fabrication process, or combinations thereof,
• wherein the mixture comprises a weight ratio of earth component:
• fiber component:
• fluid component:
• additive component of:
• about 2-50 parts of the earth component;
• about 5-50 parts of the fiber component;
• about 25-80 parts of the fluid component;
• and
• about 0-10 parts of the at least one additive component.

A structure including a composition formed from a mixture comprising:

• an earth component including a naturally occurring soil, subsoil, topsoil, clay, a clay-rich soil, sand, silt, an engineered soil formed of sand and clay, or combinations thereof;
• a fiber component including a bast or leaf fiber, including straw, wheat straw, rice straw, rice husk, reed, hay, hemp, kenaf, banana, sisal, fique, flax, jute, or combinations thereof;
• a fluid component including water, oil, acid, or combinations thereof;
• and
• at least one additive component including a bio-based additive such as cellulose, a polypeptide such as gelatin, a polysaccharide such as alginate, guar gum, locust bean gum, chitosan, and xanthan gum, and lime, or combinations thereof, wherein the mixture comprises a weight ratio of earth component:
• fiber component:
• fluid component:
• additive component of:
• about 2-50 parts of the earth component;
• about 5-50 parts of the fiber component;
• about 25-80 parts of the fluid component;
• and
• about 0-10 parts of the at least one additive component, and
• wherein the structure is a block-like geometry. a monolithic wall, a panel element. or any otherwise prefabricated building element that is fabricated via including a 3D printing process, a mechanical compression process, a manual fabrication process, or combinations thereof.
