A research team from ETH Zurich used 3D-printed moulds to make the skeletal framework for this all-concrete boat, which won first prize for design innovation at the Concrete Canoe Regatta.
The boat race takes place every other year on the Rhine river in Cologne, Germany. It challenges participants to create the lightest and fastest vessel, and race it 200 metres without sinking. The competition allows no other material than concrete to be used.
For their SkelETHon canoe, the team from ETH Zurich relied on research that allowed them to fabricate large-scale concrete building components, casting concrete in any shape using 3D-printed moulds.
"With 3D printing we have an almost unlimited geometrical freedom for making formworks, which was not available to concrete so far," said the team's Andrei Jipa. "Undercuts, microstructures, high-resolution details are now possible."
The moulds are made from recyclable plastic, and allowed the team to cast slender "bones" – some of which measured just 15 millimetres in diameter – from steel fibre-reinforced concrete.
