Automakers and suppliers are on the cusp of revolutionary change through their growing use of 3D printing, a technology that can make custom parts on demand and has the potential to mass-produce parts.
Once the technology achieves critical mass, industry analysts say, 3D printing also could affect fixed operations at dealerships.
Many automakers now use 3D printing to make prototype parts for vehicle development, as well as tools and assembly aids for manufacturing operations. Several car companies are looking into making production parts with 3D printers in the next five years. Some automakers currently produce handfuls of small replacement parts, typically interior trim pieces.
