what year that will be real ??! not soon plus there are/will be other alternatives to concrete in future.
Not any time soon: "Partially funded by the Office of Naval Research and the National Science Foundation Countour Crafting
is trying to develop 3D printed buildings using concrete."
Key words 'is trying to'. Just like there are loads of people trying to find the cure for cancers most probably.
Actually, I'm under the impression it's far more along than that:

YES,
and
why would they spend taxpayer money while the current market technologies are more than efficient i mean why change the game towards 3D printing with all progress in hand, the operation is fairly enough automated and with the 3D printing is the aim to a full automation?
new ideas and innovation.
Current building technologies are very inefficient, produce a lot of waste and require a large workforce, by comparison to this method.
