School: Aalborg University (Denmark)

Team: Team Aalborg Energy

Car Name: Carbon Killerwhale (Hydrogen Urban Concept category)

What is special about your car? The car is made of carbon fiber and awesome neon green 3D-printed parts with a total weight of just 82 kg!The car took a lot of time to design, but only a weekend to put together. So basically, anyone with a 3D-printer can print their own parts, cut the rods and sheets and build their own car. Custom fitted to their needs! And if anything breaks, just print it again and make it a little stronger or lighter! We needed a place for the phone during the race—four hours later, the case was printed and mounted in the car.

Why is fuel efficiency important to your team?

For the average person, fuel efficiency is money in the pocket as gas prices skyrocket. For the community, fuel efficiency is cleaner air in the cities, better economy and money better spend elsewhere! For Earth, fuel efficiency is us leaving a smaller footprint, making sure we have a home in 200 years. For us, it's all of the above. 3D printed parts are light weight and robust which is king in the world of fuel efficiency.

Who or what inspired you on the way to Eco-marathon? We have been inspired by the open source community. A lot of the parts on the car have been made with open source hardware (the RepRap 3D printer and the Arduino). Open source and, in particular, 3D printing, is the future and we wanted to prove that the future is now! We were also inspired by the idea of doing something no one had done before. Pioneering with a 3D-printed car is an awesome feat and we will keep pushing the limits for the use of 3D-printed parts in our car, and everything else we build!
