The Institute for Advanced Architecture of Catalonia (IAAC) completed a 100 sqm low carbon emissions 3D-printed building prototype using local soil and natural materials, utilizing the pioneering Crane WASP 3D printer, in the forest of Valldaura in the Natural Park of Collserola, Barcelona, Spain.
The 3D-Printed Earth Forest Campus is an architectural intervention featuring enclosed, covered, and open spaces made from 3D-printed earth. It serves as a live laboratory for testing new construction and architectural solutions. The project’s fragmented and deconstructed floorplan demonstrates the flexibility allowed by 3D printing technology. The spatial distribution has evolved over time, with wall sections being recycled into new walls and rooms. The organic layout aims to create diverse indoor, semi-indoor, and outdoor environments, departing from standard architectural solutions to better meet users’ needs.
3D-Printed Earth Forest Campus
The 3D-Printed Earth Forest Campus is built primarily from natural materials, with a strong stone foundation below ground and earth walls printed from locally sourced material. The walls are printed at a rate of 25 cm per day and can reach 2.5m in approximately 10 days. Roofs are anchored to the walls to avoid uplift due to wind forces.
The first phase of the 3D-Printed Earth Forest Campus (TOVA) won the “Shaping a Circular Industrial Ecosystem” prize at the New European Bauhaus in 2023. Ursula von der Leien (EU President) described it as “cutting edge 3D printing technology to print sustainable buildings made of earth.” Adjacent to TOVA, TEIXIT extends the living and working area of the forest robotic campus in the Collserola Natural Park.
