Interesting technology.

Although billed as a 3D printer I think the main technological advance is
the concrete which can be laid from a nozzle and keep its shape. It must
set very quickly as well to be able to build a complete single storey
house within 24 hours. I wonder how well this would work with normal
shuttering as a former just being constantly jacked up?

The walls are dual thickness with cavities (but not continuous) and look
as though they should be strong.

Not up to building regulations (unless the concrete is also a very good
insulator) as there isn't insulation built into the walls.

Looks pretty good for fast build accommodation on a suitable site,
although you would also have to be laying all services prior to the build.
That would go with the concrete slab for the base, of course.

It looks to require a flat site, as well.

At the moment I'm trying to work out how this stacks up against a
traditional block build using brickies.

As far as I know the main constraint to speed of build is the time it
takes for the mortar to go off. You can only lay so many rows of blocks or
bricks before you have to leave it alone to cure.

I'm pretty sure there was a mechanical brick layer about 30-50 years ago.
Ah, yes.

Haven't seen many of them around on building sites. Still better and
faster than me, though.
