You might think 3D printers are just a passing fad, a tool used to create all sorts of miscellaneous and small plastic doodads but Local Motors, an Arizona-based company is gearing up to bring out their own line of street-ready 3D printed cars in 2016. As a 3D printing enthusiast myself, this news really gets me excited about what the future will bring in terms of how traditional manufacturing will be supplanted by newer methods such as 3D-printing and CNC machining. The obvious advantage of these methods is that the products can be infinitely customized by tweaking the design on a computer and made on demand. The major hurdle to overcome is the obvious lack of speed, for example, Local Motor’s first 3D printed car, the Strati, took 44 hours to print. But there are various technologies in development such as Carbon 3D‘s CLIP technology that could radically accelerate the printing speeds by 25 to 100 times. I imagine in the car lots of the future, there will be just several gigantic 3D printers spitting out cars on demand after the customer has customized the designs to their hearts content. I suppose the big question is “When will it happen?” and not if.
