While building with soil isn’t entirely new, the idea of 3D printing soil to create a solid building is. Researchers are finding that using soil as the material can open up architectural potential as well as cutting down on buildings’ carbon footprint.
Through a new approach to 3D printing, soil implanted with seeds can now be used as a concrete-like building material. Developed by a multidisciplinary team of researchers at the University of Virginia, this building technique could open up doors to a completely new kind of building, with finely tuned ecosystems of plants and bacteria forming the insulation, the structure, even the exteriors of homes.
“It becomes like a living tissue within your house,” says Ji Ma, an assistant professor of materials science and engineering at UVA who led this research, which was recently published in the journal Additive Manufacturing.
