Researchers at ETH Zürich are showing off their construction robot who has 3D printed a temporary pavilion using stones and string as part of an exhibition at the Gewerbemuseum in the city of Winterthur.

The construction robot used thirty tonnes of loose stones and 120 kilometres of string to build the Rock Print Pavilion. The temporary installation is a research project run by Gramazio Kohler Research, the ETH Chair of Architecture an Digital Fabrication, and is part of the “Hello, Robot. Design between Human and Machine” exhibition.

The construction robot, known as the ‘in situ fabricator’, worked for a total of four weeks to build a total of 11 three-meter-high (10 ft) pillars. But the question is how can a structure made of loose stones and string support an eight-tonne steel roof?

The bot uses what’s known as “jamming,” and the ETH research project “Design and Robotic Fabrication of Jammed Architectural Structures” is focused on the robot-based assembly of simple, loose and granular base materials. The loose stones interlock together; when combined with the arrangement of string between the gravel layers – which is continuously calculated by the robot – this creates a stable, highly durable structure.

The Rock Print Pavilion is exploring the possibilities offered by digital and robotic manufacturing. Recycling is also embedded into the project: the components can be easily dismantled and the material reused.

So basically, the guy is climbing the ladder every 30 minutes to give rocks to the robot, which then deposit them in front of him, with a significant amount of failure. humans are strange.

I think this kind of demonstration is silly and gives 3D printing a bad name! >> worked for a total of four weeks to build a total of 11 three-meter-high (10 ft) pillars. With 11 biodegradable renewable cardboard tubes and 1 cement truck, you could've built it in an afternoon. Add some steel rebar to each pillar and it would probably meet code and last 100 years rather than be a construction hazard not to mention a earthquake death trap.
