Utopia or not, who knows? Ask people for some hundred years ago if they believed in cars or aeroplanes. Maybe we now living wont live as long as it takes to the day a 3d drivable car can be downloaded?

Sure, it would be extremely cool. But the reality is something else. We are still far far away from such future. These are only the beginnings and it will take decades to perfect this technology in order to be possible to use it daily and for such big things.

Not just that, but finding parts for any car you want. No more overpriced parts at the dealer, no digging through junk yards for older cars, and no waiting for shipping. just simple "I need this part, print it!"

That'd be so nice, especially When the part store is closed and you need something for that late night project, even tools.

I think he won't leave it at that. I mean, he made that wooden framework just to support the exterior parts, but there will be additional process afterwards that will polish it nicely and make it at least come close to durability of mainstream cars.

Especially the last part - "test it." I think that'd be some real fun.

Lets see how he performs at our test track in our reasonably printed car

Some 3D printers can print metals.

It won't be only plastic. There is additional process he plans to undertake after the current one is complete.

To quote the article:
"Once the exterior part is finished, he will begin the long, tedious process of sanding, adding filler, sanding even more, prepping the exterior to a glassy sheen, and then finally applying paint on its parts."

That should give it more strength for full functionality. Or at least that's what that guy thinks it will do.

@fatstarr - Exactly my thoughts. Plus, not only that it's plastic, but it's made by having to glue together the 4 by 4 inch parts. There are no larger ones, that's the biggest parts his printer can make. That's too many parts that need to be held together by glue. It's just too unstable and could break any time.
