3-D-printed car could hit streets next year. Chris Woodyard, USA TODAY

Several companies have come out with what they call "3D-printed" cars,
but none have 3D-printed the most important part, the engine.

This would be difficult to do with an internal combustion engine, with
its high temperatures, multiple moving parts, and high tolerances.

But it shouldn't be too difficult with an electric engine. In fact
considering there are now miniature 3D-printers on the market for the
home, an amateur could be the first to produce an entire, scale-size,
3D-printed car.
And then it could be scaled up to produce a full-size, working, fully
3D-printed automobile.

This would revolutionize the industry, obviously.

The two most difficult parts would be the engine and the transmission.
* Transmission not needed; look at the Tesla.


This video shows how you can make your own simple electric motor:

Looking at the steps in the video, it appears they could all be
accomplished by 3D-printing.
* GACK! A DC motor with commutator! How gross.
The working part of the engine should be exactly like the armature
in the Tesla car: design is same as armature in an AC shaded pole fan motor.
That design would not be too difficult for a 3Dprinter.
