Interesting but I see no pictures. Does this technology exist? or they're looking for investors?

There's a picture slideshow on the 2nd link, it looks like there is a working machine (probably not of a full house size though) that was used for a sculpture project.

There's a video in the press section of the first link showing the machine working.

Well, duh, there´s a reason you need steel reinforcements in complex concrete elements. Unless they can automatically generate those or their "sand and binder" material has special properties, it´s IMO at least another ten years until such a project really can be used in architecture. Besides, what´s so bad about making complex casting forms from urethane blocks to generate complex forms?

Hi Mike,

Every new technology has advantages and disadvantages.
But sooner or later someone will find an application for it.
That's human nature.

It looks to me that it's not ordinary sand. And the "binder" is likely to be epoxy resin, so it's not exactly concrete. However, it probably doesn't need reinforcement because of that. The inventor claims it comes out like marble.
