Sustainable 3D-printed home built primarily from soil

Here is a 181-word summary of the news article: A sustainable 3D-printed home has been built primarily from soil. The single-story Lib Earth House Model B was created using 3D-printing technology and a soil-based mixture instead of traditional concrete. The home was designed and constructed by the University of Maine's Advanced Structures and Composites Center. It is the second iteration of the Lib Earth House, following the initial prototype built in 2021. The soil-based mixture used for 3D-printing the home's walls is composed of local soil, cement, and other materials. This approach reduces the environmental impact compared to traditional concrete construction. The home features 600 square feet of living space and includes a kitchen, bathroom, living room, and bedroom. It is designed to be energy-efficient and sustainable, with the potential for further advancements in materials and construction methods. The project aims to demonstrate the viability of 3D-printed, soil-based construction as a more eco-friendly alternative to conventional building practices.
