State of the Art of 3D printing of buildings and concrete structures

The last years, the media has been filled with stories about new start-ups 3D printing an entire building in less than 1 day. The stories in the press have made the interest for 3D printing buildings explode with millions of downloads of the videos announced. The stories are fueling peoples hope for making buildings cheaper and for finally solving the need for affordable housing. More and more 3D printed buildings are popping up around the world and more and more precast plants are also starting to use the technology, but we have not yet seen a large scale application of the technology yet. 

So what is the real truth here ? Can buildings be 3D printed in 24 hours ? Is it all just hype, but if so what makes a company like GE invest in the technology now ? Will 3D construction printing finally disrupt the construction sector and create all the new possibilities promised ?
