In April 2021, the first prototype 3D printed house made out of clay from locally-sourced soil and water as well as fibers from rice husks and a binder, "Tecla", was completed. The housing is not only very low in carbon emissions, but could also be highly cheap, well-insulated, stable and weatherproof, climate-adaptable, customizable, get produced rapidly, require only very little easily learnable manual labor, mitigate carbon emissions from concrete, produce little waste and require little energy. It may therefore reduce homelessness, help enable intentional communities such as autonomous autark eco-communities, and enable the provision of housing for victims of natural disasters as well as – via knowledge- and technology-transfer to local people – for migrants to Europe near their homes, including as an increasingly relevant political option. It was built in Italy by the architecture studio Mario Cucinella Architects and 3D printing specialists WASP. The building's name is a portmanteau of "technology" and "clay".
