OTF: 3D Printing Architecture

Although not considered highly valued nowadays, earth has always been one of the most widely used building materials. Currently, a third of the world population lives in earthen buildings, both for its intrinsic properties – absorption of heat and humidity – and for its natural characteristics – the earth is present everywhere, it does not need energy to become a building material and it is entirely recyclable.

3D printing, as a new construction technique, potentially puts earth in the foreground. 3D printing allows a high degree of formal freedom when designing, integrating structural and climatic criteria. Thanks to robotics, on-site construction can be achieved with 0-km materials, an agile process of excavation and extraction of earth, which is subsequently filtered, mixed with natural additives and extruded as a wall or other architectural elements. Digital media facilitate the approach between the design and construction processes, supporting the building phase with computational processes, such as modelling, the production of print codes, and the mapping of soil composition and humidity, which open up new opportunities for performative architecture. Analyzing the geography and orientation of the plots allows defining the climatic needs of the facades, which can be integrated by means of the parametric modelling on walls or ceilings. A freedom that leads us to a type of architecture that adapts to each place, culture and user; that integrates material and process, valuing local crafts and construction means, cooperating with communities in both the design
and construction of the house. A future where we will live together in harmony with the land and the different cultures.
