Man, what are they teaching kids these days... Don't you know your General Relativity? Gravity and acceleration are the same thing.

I'm familiar with CNC, Stereo Lith, and variations that use metals, ceramics, etc. The problem is, you can't make most of the things people find interesting - how about a pen? A book? Anything electronic? Anything with parts that are made of more than one material? How about an electric motor, necessary for half the gadgets in your house? The only things these kinds of technology will allow you to make are relatively simple mechanical things, which if you think about it, aren't very interesting. Almost all the mechanical things I'd want in every day life (apart from car parts) are availble from Target for next to nothing already.
Once again, a so-called futurist proves to be purely for entertainment value:)
Sounds like there's a pretty big loophole to me - technically speaking, low earth orbit is not zero-gravity. The gravity that close to the earth is almost as strong as it is here on the surface. The onyl difference is that you're zinging around at 20,000 MPH, thus keeping yourself from falling out of the sky.
