You cannot build a complete car. Many car components cannot be made of plastic. (e.g., motor, wiring, etc.) It's unlikely the plastic can withstand the stress that other parts experience. Think about it: plastic is less dense than metal. If it could be made of plastic, many of those parts already would, as a way to save weight, which translates into better fuel efficiency.
Also, 3-D printers will likely be no more common than CNC machines in people's houses. Except for serious hobbyists, few people will ever bother to own a 3-D printer - there really isn't much to print that wouldn't be more economical to just run down to the store and purchase.
in the short term yes.
Once carbon fiber or something with similar properties is printable the paradigm shift will happen.
Its gonna be all about who can afford the materials.
The only types of things that you'd print would be items that are not manufactured for whatever reason. I don't think it's conceivable that a 3-D printer is ever going to match mass production for the final cost of goods.

a lot of work is being done in additive manufacturing of metal parts, but you're looking at extremely high value-added applications (mostly aerospace industry) where this is being used. you save a hell of a lot of time and money when you cut down on lead times and reduce machining time/cost.
Will 3D printers come with warning labels "Do not use to create 3D printers"?
How long do you think costs are gonna be prohibitive before extrusion is cheap enough that say a F1 team can make parts in the pit? When that happens the enthusiast market isnt that far behind is it?

Didn't a 3d printer of some sort help the Chinese build the biggest building in the world in record time or something?
