Collaborating with robotics engineers and Italian 3D printer manufacturers, a Japanese company is building “homes of earth” made primarily from soil. Utilizing AI technology from design through construction, Lib Work, Ltd. completed their first 3D-printed earth home in Yamaga, Kumamoto on July 22, calling their creative process “uncharted territory where tradition and convention offered no guide”. With an eye toward recycling, sustainability, and reduced carbon emissions, Lib Work focused on combining 3D-printing with natural materials enhanced for strength, constructability, and design quality. The walls of the completed Lib Earth House Model B use no cement (which produces industrial waste). Instead, they utilized only naturally derived materials with soil as the primary component to create sustainable earthen walls. Compared to the previous model that used some cement, the building’s strength has improved approximately fivefold while significantly reducing CO2 emissions from the manufacturing process itself. The company aims to construct 10,000 units by 2040.
