"A Simpler, Streamlined Build
The Strati is a sleek two-seated, roofless electric vehicle that weighs about 2,200 pounds with all its non-printed parts attached. Most of the car was constructed in a shipping container-sized 3-D printer, which used nozzles to squirt layer after layer of a carbon-reinforced thermoplastic to construct the chassis from the ground up. The end product looks a lot like a topographic map of an Italian roadster (see the assembly video below).
The primary advantage of 3-D printing the Strati is that most of the chassis components are already complete after it comes off the printer. Once the steering wheel, shocks, tires, electric motor are all quickly installed, it can be driven off the lot.
The Strati can reach speeds of about 40 miles per hour and can travel 120 miles on a charge, but a gas engine could also be fitted. Local Motors expects the Strati to retail for about $18,000."
ETA:"When asked what would happen in a crash, though, Mr. Earle, driving the two-seat car, said it would be like a rock slamming against a brick wall."
