Nobody knows just yet how the auto industry will adopt 3D printing. But Desktop Metal Inc. (Burlington, MA) is in a better position than most to make an educated guess.
There is a lot of promise in the coming adoption of Model-Based Definition (MBD) in industry. MBD is the practice of attaching useful information to a 3D CAD model, such as tolerances or material properties. This should be especially good news for manufacturing engineers.
