Design Boom reports on a new 3D printing process developed by ETH Zurich. This process has been used to produce nine individually designed concrete columns.
This process “allows the production of concrete elements without the need for any formwork. In addition, one-of-a-kind designs with complex geometries can be fabricated in a fully automated manner. Hollow concrete structures are printed in a way where the material can be strategically used only where needed, allowing a more sustainable approach to concrete architecture.”
This project was completed “in collaboration with the Origen Festival in Riom, Switzerland. The installation, which has been dubbed ‘Concrete Choreography,’ consists of nine 2.7-meter-tall columns (8.9 ft each). Each column is concrete 3D printed at full height in 2.5 hours with the process developed by ETH Zurich, with the support of NCCR DFAB.”
“Students of the Master of Advanced Studies in Digital Fabrication and Architecture explored the unique possibilities of layered extrusion printing, demonstrating the potential of computational design and digital fabrication for future concrete construction.”
“Computationally designed material ornament and surface texture exemplify the versatility and significant aesthetic potential 3D concrete printing holds when used in large-scale structures.”
This installation will “frame and inform the dance performances of the 2019 Summer Season in Riom. The project showcases how technological advancements can bring efficient and novel expressions to concrete architecture.”
