Strati by Michele Anoé
The winning car has a sporty body and an accordion-pleated retractable roof. Its body is a single block 3D printed in ABS around an aluminium frame and roll cage, with carbon fibre supports on the front and rear.
ISF -- Internal Strut Frame by Greg Thomson
Greg Thomson's ISF is inspired by the bone structure of birds' wings, and its frame is printed in a single piece, offering lightness, durability and an aerodynamic form. "The ISF is a study in creating a new generation of automobile that relies not on forms found within the conventional manufacturing processes but is rather a design that results solely from shapes that can only be created and produced through means of additive manufacturing and 3D printing technologies," Thomson wrote.
Aeroblade by iMAN Maghsoudi
Based on the concepts of aerodynamics, safety and aesthetics, Aeroblade is 3D printed in one piece with a unique blade structure that conducts the airflow through and around the vehicle. For an advanced safety feature, designer Maghsoudi said, parallel sandwich blades are wrapped around the cockpit to absorb impact.
3DPCX by Sasank Gopinathan
This doorless sports vehicle was designed around the idea of one swooping structure surrounding the car's occupants, with a central spine to support the car. 3D printed ribs provide additional support, and the rest of the car's body is intended to be 3D printed in separate pieces.
Supernova by Sebastian Dib
Smooth and sleek, this luxury car has no angles greater than 45 degrees -- with the exception of the wheelhouse. Creator Sebastian Dib even printed up a scale prototype all of one piece, showing how the car provides easy access to battery and engine through the wheelhouses and underneath. "I got inspired from the supernovas, from one moment to another they explode in a very aggressive way creating all the elements in the universe, the gravity makes its work forming solar systems, and at the end everything find its order," Dib wrote of his design.
Mirage by Kai Y
Mirage is so named because, while it looks smooth and sleek, beneath the surface of its body are complex structures that provide support, only achievable through 3D printing, including 3D printed crumple zones. "Utilising multi-material printing, we are able to layer soft rubber-like material on top of hard plastics to provide comfort and safety," designer Kai Y wrote. "We looked toward nature for inspiration, by applying synthetic sharkskin texture onto vital areas, aerodynamics is greatly improved. The MIRAGE is a culmination of elements that work to provide not just technical performance, but also elicits an emotional response from the user."
E-spider by Xavier Gordillo
This tough little off-roader has been designed, creator Xavier Gordillo said, to minimise material use while maximising strength. Its frame is inspired by bones, with space in between. These holes -- as well as a roof -- can be added to the vehicle when conditions demand, with other detachable elements, such as the windshield and roof struts, inspired by children's toys.
