In Colorado, one man turned a two-car dream into a one-car project and printed the rest himself. Working with a budget of around $20,000, he and his son scaled up a digital model of a Lamborghini Aventador, then 3D‑printed the body panels and many components piece by piece before assembling them in the backyard. Nearly every visible surface is printed plastic, sitting over a Corvette V8 rather than a factory V12, yet the finished car looks startlingly close to the real thing.
