World's first 3-D printed cars go on sale next year

For those frustrated at having to search dealers' showrooms for just the right set of wheels, along comes an innovation that could make acquiring a custom-made car as easy as a few key strokes on a keyboard.

A US company said this week that it plans to produce what it's calling the world's first 3-D printed car. Phoenix-based Local Motors says it plans to make them available for sale in about a year at prices ranging from US$18,000 (NZ$23,200) to US$30,000 (NZ$38,600).



The basic idea is simple: Buyers would be able to select their ideal car off a computer screen, then hit the print button. A giant machine would then start making the car out of carbon fibre-reinforced plastic, weaving it out of thin lines of paste that harden to form the chassis, body and even the dashboard. The process takes about 40 hours.

Some of the car's major components are then attached to complete the car, like the wheels, controls and powertrain.

Instead of about 25,000 parts in some modern cars, Local Motors says the prototype that it has been showing off in Las Vegas at the Specialty Equipment Market Association (SEMA) trade show has about 50.

Because the car is easily changed on a computer screen, it can be shaped to however the buyer would like it, says CEO John "Jay" Rogers.

"If I want this car to be 10 per cent bigger, I just click a button," he says.

Don't like the model called the Strati? Just hang on to it for a few months, then go and choose another model. The 3-D designed-car will be recycleable as long as it has not been painted, Rogers says. Buyers quick to change fashions can ground up their existing car into fine particles again and use the materials to make a new model.

Rogers says the car will pass safety tests. And unlike other cars that can take months for improvements, Local Motors can change any part of its cars with a few keystrokes, allowing changes within hours of a crash test.

The notion of a 3-D-printed car "sounds feasible at some point," says John O'Dell, an editor for Edmunds.com, which specialises in eco-friendly cars.

He noted that handcrafters have made one-of-a-kind cars for generations, so the notion of a car made just for a particular person isn't entirely new. Those cars, however, were generally not the for the masses. Rather, they appealed to the whims of the super-rich in the past century.

So O'Dell says he'll watch with interest to see if Local Motors can pull off the idea of 3-D printed cars for the masses.
