Students' 3D-printed Concrete Choreography pillars provide a stage for dancers

Dancers at the Origen Festival in the Swiss Alps will perform around nine unique columns 3D-printed in concrete by students from ETH Zurich. The masters students produced the columns using a new process, developed at the technology school, that allows for the fast 3D-printing of concrete structures completely without formwork or any other kind of mould. Titled Concrete Choreography, the series of structures took less than two-and-a-half hours to print in the lab using an industrial robot a
