The printed racecar
A team of engineers in Belgium have created a racer called the Areion. Using a process called "mammoth stereolithography" that prints out large, custom objects, the team constructed a fully-printed 3D chassis for their car.
The car is able to reach a top speed of 88mph, going from 0 to 62mph in 3.2 seconds. 50-volt lithium batteries power the racer, sending charge to an 85kw motor. Double-A carbon wishbone suspension, a bio-composite electric drivetrain and composite racing seat bring the weight of the car to 617 pounds.
A printed nozzle and diffuser keep the motor cool, and a fan behind the radiator draws in air on the left. In the right side of the shell, channels were developed and printed to create a cyclone effect which prevents water and dirt from becoming airborne and entering the engine.
