A slightly more informative video about how it works: https://www.youtube.com/watch?v=XeTdo-w6Qx8 https://www.youtube.com/watch?v=XeTdo-w6Qx8 Edit: And another much more informative video about the actual printing process: https://www.youtube.com/watch?v=VXntl3ff5tc https://www.youtube.com/watch?v=VXntl3ff5tc Looks like it uses black ink printing onto plastic beads spread on a printing bed to make some sections melt under light and others not. Edit2: Probably not actually "black" but "UV Absorbing" for the ink.

the contained waste material recovery is a nice touch :) now, where did I put my piggy bank...

It almost certainly uses black ink. All parts produced with the machine they have now are to be black. It technically doesn't use beads, it uses plastic powder. It works exactly as you described though.

  Oh, yeah. I put the UV part in there because of the talk about full color printing. The first time through that video I missed the key phrase "could in the future"[1]. [1] https://www.youtube.com/watch?v=VXntl3ff5tc&t=3m27s https://www.youtube.com/watch?v=VXntl3ff5tc&t=3m27s

    Why would you need UV absorption for color printing?
    - azdle 10y ago
      Well, I'd assume white counts as a color, as well as other light colors. Plus they then go on to talk about printing clear things. You need to absorb energy from somewhere so I figured UV was about all that was left.
