Using  3D printing, scientists have developed a paddling submarine that requires no engine, propellant or power supply.

Researchers at ETH Zurich    have developed a new propulsion concept for swimming robots. The robot exploits temperature fluctuations in the water for propulsion without the need for an engine, propellant or power supply.

As a proof-of-concept st udy, the researchers developed a 7.5-centimetre mini-submarine equipped with paddles, which they fabricated entirely using a multi-material 3D printer.
