10 years ago, Ford 3D-printed perhaps 4,000 prototype parts for its vehicles. Today, just one of the automaker’s five 3D prototyping centers churns out more than 20,000 parts annually. 3D printing is relatively new to the consumer market, but manufacturers like Ford have been using it for nearly 30 years. A single print run on one machine can create anywhere from a few parts to hundreds of thousands of parts. The 3D printers range in price from $250,000 to high six figures.”]
