Mass is more appropriate than volume here, but point taken.

  Sort of. You still need support materials if you were making something hollow. But anyway, this is pedantic details. We both get where each other is coming from.

    How about getting the raw materials like tap water?

      It'd be kind of possible. Not all of them use liquid materials, but even then, the ones that do look like this: http://www.youtube.com/watch?v=nwQ5HA8sE-k http://www.youtube.com/watch?v=nwQ5HA8sE-k Right now, you load the material into the machine with a small crane-like thing. So theoretically, I guess you could hook up piping instead. But that's still a honking big machine, and you'd need a machine that'd be larger than the things you're building with it, really. I think eventually, it could happen. It's just not going to happen any time soon. My favorite theoretical material supply scheme is grabbing carbon out of the air and re-configuring it into whatever you're printing with ;)

        How about grabbing stuff out of the ground?
