I see 3d printing as an interim technology. We've gone nine rounds about how much it sucks.
But this guy right here is a perfect exemplar of what 3d printing should be, and makes the candyfab look like a joke.
It's cool that this guy wants to make these more affordable and it's pretty neat how he redesigned it, but I really think that the video could have been improved if it showed the thing producing parts of something that people will use. Maybe I'm in the minority, but I'm having trouble thinking of stuff I would want to print. I certainly don't have a use for "hollow cubes", at least not off the top of my head.
