Abstract

A 3D printed structure is provided. The structure includes a composition that is formed from a mixture. The mixture includes an earth component, a fiber component, a water component, and at least one additive. The structure includes an insulation portion and an exterior support portion surrounding the insulation portion. The exterior support portion includes an earth: fib er: water weight ratio of about 65:4:32. The insulation portion includes an earth: fib er: water weight ratio of about 65:244: 1480. In some embodiments, the structure includes an interior support portion that is positioned at least partially between the exterior support portion and the insulation portion. The interior support portion includes an earth:fiber:water weight ratio of about 65: 12:67.5.
