The Tecla house is a prototype 3D-printed eco residential building made out of clay. The first model was designed by the Italian architecture studio Mario Cucinella Architects (MCA) and engineered and built by Italian 3D printing specialists WASP by April 2021, becoming the world's first house 3D-printed entirely from a mixture made from mainly local earth and water.[1][2][3] Its name is a portmanteau of "technology" and "clay" and that of one of Italo Calvino's Invisible Cities whose construction never ceases.[1][4][3][5]
