Print a Vacuum Cleaner

Very interesting.
Sterling's been harping on this for quite a while. And, like all predictions, I assume it will be partly wrong. However, it will be interesting to see what is correct.
I think the biggest thing after self-production will be cradle-to-cradle. We're starting to see great advances in the use of traditional materials: glass, metal, fabric. Traditional foresight predicted "magic" exotic materials, whereas we're starting to get such a handle on the existing materials that we have exotic implementations of old, boring things. Gorilla glass is a good example: plain glass, but with a couple of atoms replaced and moved around. We no longer have to tape a clock and a radio together to make a clock-radio.
Being able to use these materials everywhere means that it's easier to melt down your phone to fuel whatever looks good on github.
Anyway, I wish they focused more on the real advantage of these things which is to produce replacement parts when a 5 cent piece breaks on a 100+$ object. Think being able to replace the little plastic tab on your remote control so you don't have to resort to duck tape to keep the batteries from falling out. Or one of those clips on your backpack that let's you readjust things without just tying a knot in them.
3D scanners have been touted as a way to solve this (scan your object, print a new one) but I don't think the resolution will be high enough any time soon to print reasonably aesthetic replacements. The real solution in my opinion is to make MCAD easier and more affordable so it's easier to design a replacement then to walk to the store.

So, even if I'd had to buy everything from scratch, it only would have cost me ~ $15. Since that wasn't the case, it only cost me my time and some negligible expenses. Meanwhile, the cheapest portable vacuum cleaner I could find at the stores I went to was $39.99 + tax...
Also, we're not that far from printing motors. Fab@home has printed metal by dissolving it into a thick paste and others have printed grooves and run solder through them. Once I can print metal coils, I can print a motor... (Some motors don't need an internal magnet -- see http://en.wikipedia.org/wiki/Induction_motor)
There are areas where it's an obviously better/cheaper solution than the alternatives. The best example I've seen recently was the Pixar 3D zoetrope.

Each item is unique in the world, they only need 1 of each (per zoetrope), they already have 3D models in the computer. Another niche I heard about was classic car owners printing out moulds to cast replacement parts for their cars. Or the guys that prototyped the glif stand for iPad. These are the things that these will be used for first.
I wonder what laser printers were first used for when they were tens of thousands of dollars to purchase? And if anyone's graphed the decline in price and increase in availability/usage over time and compared it with 3D printing's progress to guess when we'll all have one to print out our kids latest 3D model and display it proudly on top of the fridge.
It's really pretty amazing. But the very sad thing is that the kidney printing (http://www.shockmd.com/2011/03/10/printing-a-human-kidney/) would get less funding than a mainstream application of what you've done.
When the price of open source 3d printers decreases to a couple hundred dollars and their quality has steadily improved for 5-10 years will it matter which cash cows corporations are chasing? In a world where you can just go to your computer and print a kidney for yourself they may just be entirely irrelevant.
disclaimer: if you print yourself a kidney, please get a certified doctor to install it :)
EDIT: watching the ted talk. He's using custom machines, very impressive in-body printing.
As an aide, most people like the idea of innovation, but when they see it up close, their reaction is often ugh.
PS. Just emailed Chris, he'll be super excited to see this!
