On the one hand, that's great.
On the other, we better really get going on concrete that has a lower CO2 footprint if we're going build all the housing stock this way.
Also, I wonder about the insulation. It looks like the concrete is sort of an envelope that is filled with something (foam?).
Finally, the walls tend to be the easy part, especially on a single-story house. Once you have a flat slab, the walls go up in a few days with a competent crew.

It would be really cool if they could 3D print a home out of cob (waddle and daub) which is a mix of clay, sand and straw (or other fiber.)

Is this 3D-printed home made of clay the future of housing? - CNN Style

I've run across another high-end, artsy clay 3d home, too. And, IIRC, the proposed Mars 'habitats' are 3d dirt prints (look like tall beehives in artists' renderings).
I'm surprised aircrete hasn't been tried.
