Electromobility is a crucial topic of the future. For Germany to be in the pole position, it is important to inspire young minds to take up scientific and engineering professions. Towards this purpose, the annual JET Challenge takes place at the IdeenExpo in Hanover. Students are given the task of building a fast, tough and energy-efficient racing car from a standard, remote-controlled car with a limited budget. Wear-resistant 3D-printed gears from igus made from the high-performance plastic iglidur I6 helped in this endeavour.
