A great deal of hype surrounds the 3D printing of concrete, but the old dilemma remains: even printed concrete requires some cement – and cement production alone is currently responsible for 8 % of worldwide CO2 emissions.
For Mario Cucinella Architects this was reason enough to look around for suitable alternatives. They found what they were looking for literally under their own feet: the idea of constructing buildings primarily out of locally dug earth has been common practice for thousands of years, for example in rammed earth and adobe construction. Together with Wasp, a company specialising in 3D printing, and a number of other industrial partners, the architects have developed and built Tecla, a dome-shaped, monolithic prototype building that mainly consists of earth, straw chaff, rice husks and a binder of lime and water.
