Swissloop Tunneling

Swissloop Tunneling is a student-led association based at the Swiss Federal Institute of Technology (ETH) Zurich conducting research on tunneling solutions. Last year, the Swissloop Tunneling team designed and built their first tunneling machine, “Groundhog Alpha”, named after one of nature’s most creative tunnel building animals. With its unique steering mechanism and progressive tunnel lining system, “Groundhog Alpha” is more agile than conventional solutions and can 3D-print the tunnel tube while continuously moving forward. This is something that has never been done before.
