3D Printing With Clay, Aggregate and Straw

Terran’s 3D printing system emulates traditional adobe hand-building techniques to produce walls that are soundproof and fireproof. Using reinforcement learning, they are training custom-designed unmanned aerial drones to emulate traditional earthen building techniques.

By leveraging the world’s most abundant building materials—clay, aggregate, and straw—Terran walls save 50% on construction costs versus conventional stick-built walls.

Terran’s system saves time and money by reducing the number of different materials required and replacing at least four subcontractors: framing, drywall, siding and insulation. From cradle-to-cradle, Terran walls produce about 80% less C02 than conventional wall systems (stick-built or concrete). The materials in Terran walls are non-polluting and non-toxic. And the combination of high thermal mass with natural humidity regulation means lower energy bills for homeowners.

Their adobe-printing drone works in a 2-step process: picking and placing the adobe building material, and sculpting the material into the desired form.

Custom built-ins are also possible with this system.

In 2022 they will begin building homes in the Midwest, expanding to other regions based on demand.
