From what I see, 3D Printing is bound to have a massive effect on the Automobile industry.

PARTS:
- Just imagine. If you have an old car that needs a replacement part, aftermarket parts can be very expensive. If you have a printer at home that can print your parts, you will save a ton of money. Once metal printers become common for consumers, this is something I expect to see a lot more of.
- This saves so much not only in terms of money, but in terms of manufacturing and waste. No more uneeded production of parts. They will be able to be printed as need be.
- Recycling is easier. Raw materials that 3D Printers use can be recycled back into their original source material.

CUSTOM CARS:
- Think about all the customizations people will be able to do to their cars. Now you have to buy manufactured parts, or kits in order to customize your car. They aren't really custom though, are they? With 3D Printing, you can make your own parts, any which way you want.

I know I'm excited about what 3D Printing will be bringing to the Auto industry. Any other cool things that we should see in the Auto Industry due to 3D Printing?
