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.

MPAA is for motion pictures. 🙄
Probably a DMCA takedown of the pattern involved.

I was in chilies and read on their kiosk on the table on USA today that one of the options that Obozo could do to seek revenge on the DPRK Sony hack would be to drop DVDs of the Interview. I said to myself shit, just drop zombies. LMAO!

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.

probably within our lifetimes true. For the long term the expense of tooling and keeping around the machinery to produce older parts for cars and factories will eventually exceed the cost of making those parts via 3d printing. Specialized and expensive parts will eventually hit a parity point cost/part and then the industry will change/adjust.
I cant wait till printed food.
He was asking if the MPAA would remove the "You wouldn't steal a car" line from their anti-piracy campaigns, though I've personally never seen this before a movie, the campaign in question is at least 7 years old, and it's 'steal' a car not 'download' a car, though the MPAA is retarded as I would totally use a 3d printer to make a copy of a lambo at my own expense. 🙄 😛

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.

While maybe not a combustible engine any time soon, there are other ways...

here's a decent opinion piece on why it's a bad idea to regulate what we can copy/print.

Groups like the MPAA would keep you from making copies of music purchased. Apple and other companies have attempted to crush others for ridiculous appeals to trademark and copyright law. IP? Billions on battles and someone just allowed circumvent that? I know we're not printing iphones but once someone believes there's a threat on which a profit can be made then money will flood the war chests in DC to act.

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?

They will probably give the hardware away eventually. It will all be about the materials.
It will be the new printer ink.

extrusion on additive manufacturing? extrusion is used, at least in aircraft, but you still have to machine surfaces, drill holes, etc. so extrusions are generally not finished products.
additively manufactured parts, depending on the method of manufacture, can be used (in theory) directly after finishing production. however, things like surface finish, tolerances, part strength, corrosion finish, etc. may require post-manufacture operations.
for example, any powder-based method generally has a poor surface finish, which greatly reduces fatigue life. so some sort of surface finishing operation - whether machining, grinding/polishing, chemical milling - needs to be done to achieve a "normal" fatigue life.
another example might be with the powder bed method - you might want to heat treat after the part is finished to ensure uniform microstructure and mechanical properties within the part.

You can get closer than you might think -
The plastic engine consisted of metal cylinder sleeves, metal combustion chamber tops, metal piston crowns, bearings, valves and seats, and a stock 2.3L Pinto crankshaft. Nearly everything else in the engine, including the block, rods and piston skirts, were made of Torlon thermoplastic resins manufactured by Amoco Chemicals Co. - with 1980's technology no less...

^^ many small 2 cycle engines are now largely made of plastic as well.
