3D printing a house

thought it may have taken a few years to get to this point but apparently its already possible

Interesting possibilities.

Of course concrete houses often aren't considered great in the UK.
But then you can always knock it down twenty years down the line and rebuild it to your current wants by getting the robot back for a day.

Of course, no reason the house-making robot can't lay bricks either.

Seems I'm definitely not the first to think about that.

But who's going to wolf-whistle at all girls now?

On that - you're having a party next week and want a couple of extra rooms, so give the company a shout and book a slot to do you an extra bedroom and a second reception room.

But then, does it have to be THAT big. Get it on wheels with a big articulated arm and you just get them to dump the raw materials in some collapsible hoppers, connect up the water, plug it in the mains and let it do it's thang.

Looks clever but will probably cost a small fortune even though concrete is cheap.

I want to build a cob house. Mud, straw and sand are the only things you need on top of good solid foundations.

Big dollops of bullshit!

What's the point?
There's no cost or time saving!
You still need to construct the shuttering before pouring the concrete!
You still need steel fixers to place the rebar before the concrete is poured.
"Fibre reinforced concrete", how does that work, if it's poured in layers?
Answer, it won't! How do the fibres bridge the layers of concrete?
Concrete structures, simply, do not work the way the video implies!

If you wanted rebar it would presumablybe easy to have something insert rebard into the paste they are applying.

It looked me that the layers of concrete-paste were squidged together.
Whether that's enough for the 'fibre' to bond between the two is another matter.

It's unlikely what they demonstrate would be the final machine.
But I don't think it would be a big jump to have a similar system laying bricks and mortar.

You cannot insert rebar into concrete, the individual bars need to be tied, in-situ, to each other, or are welded to each other prior to arrival on site, even then the individual components still need to be tied to each other.

A properly reinforced concrete wall will have a series of shaped steel loops, in the horizontal and vertical planes, all tied to each other and tied to the reinforcement rising from the base/foundations. The reinforcement needs a 20 - 50mm covering of concrete, depending on the wall dimensions.

Where was the aggregate in the concrete, being layered up, and how would it fit through the nozzle?
If there had been aggregate in the "layered" wall, the "wall" would have slumped under its own weight!

That layered wall, shown in the video, could never be used as a load bearing section, it has virtually no shear strength.
