At the RAPID event next week, a company called Forecast 3D will be on hand with a racecar called the Harbinger. It features 45 different 3D printed parts, from the shift nope to the fender flares, going to prove that 3D printing can be used to make fully function parts. If proof is what you are looking for, how about an entire race season? That's how this car and its parts were tested.
