The Japanese company Lib Work is using earthen materials to 3D print homes. House Model B is a 1,076-square-foot, single-story residence built mainly from earth, lime, and natural fibers.
Lib Work says improvements to the overall manufacturing process have lowered its carbon emissions and the building itself is about five times stronger than their previous design that included cement.
To fabricate the home the company worked with Italian 3D-printing firm WASP to construct the initial shell. WASP configured their equipment on-site to create Model B’s shape with the soil-based composite material and a blueprint.
Once completed, workers then coated the shell in a protective glazing before installing doors, windows, and plumbing.
The Model B is completely off-grid, using a battery storage system and solar panels, along with energy efficient A/C, lighting, and water heating devices.
Sensors embedded in the walls monitor for condensation and insulation performance over the prototype’s testing phase, as well as measure for any structural degradation.
Unlike standard houses, Model B is designed for eventual deconstruction, allowing much of its materials to return to the earth, reducing landfill waste and environmental impact.
