The days of the iconic car assembly line seems to be numbered. 3D printing technology will one day scale up for mass production of full-size automotive components and body panels using molten polymers, allowing manufacturers to build cars to microscopic exacting standards without the space currently required for assembly line manufacturing. The transition should result in lighter, better built, easier to construct, and more affordable vehicles. Cars will also probably look nothing like the vehicles on the road today once 3D printing becomes the standard.
