Japanese company Lib Work has introduced a groundbreaking approach to 3D house construction, using soil as the main material instead of traditional concrete. Their innovative process, called Lib Earth House Construction, employs a large-scale 3D printer to create homes from a unique blend of earth, slaked lime, and natural fibers.
This method is reminiscent of the ancient technique known as wattle and daub, which has proven to be durable for centuries. Lib Work boasts that their structures have an earthquake resistance rating of grade 3, the highest level in Japan, ensuring safety for residents in seismically active regions.
The recent unveiling of their more advanced Lib Earth model B showcases a significantly more complex design than their first iteration, which was a simple hut. This new model emphasizes versatility, allowing for creative architectural forms that traditional materials struggle to accommodate.
The construction materials consist of 65% soil and sand, supplemented by slaked lime and a small proportion of natural fibers. Lib Work has conducted measurements indicating that the environmental impact of their eco-friendly homes is significantly lower. A typical house using conventional materials might produce around 45,000 kg of CO2 emissions, whereas their new construction technique reduces this figure by over half, leading to just 22,434 kg of emissions.
Additionally, Lib Work is exploring the potential for using Martian soil as part of a project aimed at creating habitable structures on Mars, indicating their ambitious vision for sustainable living not only on Earth but beyond.
