In a groundbreaking development for Latin American architecture, a team from the University of Bío-Bío has constructed the region’s first 3D-printed concrete home, aptly named the “Casa Semilla” or “Seed House.” This innovative project showcases the potential of 3D printing technology in addressing housing shortages and promoting sustainable building practices.
“This is a very revolutionary technology because it changes the traditional way of building, where plans are made, products are quoted, a large number of elements have to be purchased and the land prepared, which is time-consuming.
— Rodrigo García, University of Bío-Bío
Leveraging Advanced 3D Printing Technology
The construction process employed a KUKA KR120 industrial robot in conjunction with the Atenea-UBB printer. This combination allowed for the precise layering of concrete based on a digital architectural model. Remarkably, the seven concrete walls of the 30-square-meter structure were completed in just 29 hours, with the entire assembly finalized over the subsequent two days .
A Model for Future Housing Solutions
Led by architects Claudia Muñoz and Rodrigo García, the project aims to revolutionize traditional construction methods in Latin America. By demonstrating the efficiency and adaptability of 3D printing in architecture, the team envisions a future where such technologies can be harnessed to meet the region’s pressing housing demands, especially in areas prone to natural disasters.
Implications for the Architectural Community
The success of the Casa Semilla project underscores the transformative impact of integrating 3D software and robotics in architectural design and construction. As the industry continues to explore sustainable and efficient building methods, this initiative serves as a compelling case study for the potential of digital fabrication in real-world applications.
