I don't see how this is a big deal. Yes, 3D printing brings manufacturing to a personal level, and it is an important step in technology, but it's nothing that's really that amazing if you think about it. Manufacturing already occurs on a mass scale every single day, yet no one gives a second thought to it.

You buy something in Walmart -- do you ever think about how the product is actually made by robots, made out of metal and powered by real-time operating systems painstakingly coded by software engineers, who then in turn wrote them on software that was painstakingly coded by different software engineers, that ran on hardware that took engineers decades of innovation and miniaturization to achieve, that was created by slightly more advanced robots in some other factory?

No, you don't. You pick up the damned thing, walk over to the cashier, and buy it and move on with your life. It's the same thing with 3D printers. It's a PRINTER. It's not God, it's not the Higgs Boson, it's not the next step in string theory, no new quantum mechanics theories have been discovered, and no, Jurassic Park still can't be created, even if we do have mammoth blood.

On another note entirely, it's amazing how articles like these can make a (supposedly) young 15 year old like me feel like a completely Luddite-esque curmudgeon.
