| Rapid Clay Formations, 2020 |
| Full-scale Mock-up for the SE MusicLab project, Brunnen |

The Rapid Clay Formations project implements an in-situ robotic fabrication process for building with expressive soft clay bonds by robotically compressing clay cylinders at a large scale. The project makes use of accurate robotic positioning, spatial orientation, and controlled pressing of clay cylinders to form interlocking aggregations. It uses computational design and fabrication strategies to arrive at a sustainable construction technique as an alternative to labor-intensive rammed earth structures.
Preliminary material and robotic assembly research were conducted for a pavilion at the World Congress of Architects UIA 2020 during a 10-week design research workshop where students of the MAS ETH DFAB, together with researchers of Gramazio Kohler Research, were able to develop an apposite earthen material mix for the cylinders and a series of fabrication- and material-aware computational design strategies. The team implemented robotic processes that allowed building at full-scale and set up the tooling for controlling the robotic end-effector for picking, placing, and pressing the clay cylinders onto the main wall structure. The development was continued by our team together with our industry partners Lehmag AG and Seforb Sarl, aiming for its application in a real-world construction project. In September 2020, the results of this study were carried out at Lehmag AG in Brunnen, Switzerland, where the team realized a full-scale mock-up of an undulating clay wall of 5m height for the SE MusicLab in Bern. The prototype consists of more than 8000 cylinders, divided into 25 fabrication segments each with its respective robot position, and has been built over a period of 3 weeks.
