Cultural site from a 3D printer

ETH engineers and architects are planning a 23-metre-high tower made of 3D-printed columns for the village of Mulegns on the Julier Pass. Construction is scheduled to begin in spring 2022. Three professors from D-BAUG are involved: Robert Flatt is working on the concrete mix, the "ink" for the 3D printer, so to speak, Walter Kaufmann on the supporting structure and the connections of the printed concrete elements, and Andreas Wieser on the measurement and shape control.
