I wonder if bubble chain homes will have a surge in popularity as three or four circular bits get attached to one another.
You remember those concrete domes that were basically like paper mache over inflated pillows? There's one out in the Midwest somewhere painted to look like a psychedelic caterpillar, that's like 4 overlapping domes in a chain.

@stacksofplates this same printer can make a square or any shape needed.
True, but as the arm operates radially, the largest footprint for any length arm will be the full swing of the arm, and not its inscribed square. They already look pretty small.
I've seen proof of concepts with others that look more like dry dock cranes that do larger rectangles really well. But mobility is low, obviously. This one looks like you can put it on a truck and drive it from pad to pad.
Yeah, it's certainly possible. This one looks like the budget "Habitat for Humanity" model.
It's perfect, from what I see, for the third world. In Nica they do man made houses not unlike this but in little squares. This looks like it would do a larger footprint with a cooler design and more solid construction (although they do all cinder block so they are already really solid) with less transportation costs (cinder blocks have to be brought from somewhere.) I could totally see Central American housing developments being made with these.

Uh oh, now the queen wants a castle...
You mean all us minions get to go live in the castle after it's built, right?

A lot of the excitement around this stuff is less the size and more the ability to explore designs that were impractical before.

If I recall correctly NASA and the private space companies are looking into this technology to build habitats on the moon and mars. The problem they keep running into is how do you get the raw materials there in a consistent manner.

You have to figure out how to produce the raw resources on site... at least as much as possible.

Yep, from the reading I did last year Mars has some decent aggregate that could be harvested by a robot. They still need some kind of binding agent and the most common one, and the one that often works the best, just isn't available on Mars where and when we'd need it.

That'll be a great way to go. They just need to create a cement factory there too, which is totally doable.

@scottalanmiller With what water?
I suppose if they can pull the Hydrogen and Oxygen out of the surrounding material and condense it into water then they'd be able too..
But it's not as easy as going to the local stream and collecting a few billion gallons of the stuff..

If we are talking Mars or the Moon, there is expected to be water there.

@scottalanmiller The moon and mars have been determined to have very little accessible water. And the ice on mars is yet to be confirmed as even accessible.
If it is the next issue comes in as how do they break the ice apart and pick it up, and then how to melt it. And then how to mix it.
And lastly the tech for all of these printers is based around being in the center of the structure. Which poses some issues, such as completing the roof.

There are some 3D structure printers that are more akin to a shipping container crane. They can print some pretty large building too.

@DustinB3403 You remember The Martian? That turning 1 liter of hydroxide into 4 liters of water actually works. Mars might not have much of an atmosphere, but it doesn't take much.

My only question is where is the rebar?

They were using fiberglass instead of rebar for that extra support.

IIRC once hardened it functions almost identically to rebar reinforced concrete. Which is kind of amazing.

Conventionally-poured concrete allows for whatever odd shapes, addition of reinforcement, and also for placement of pipes and conduits. While this is cool in a very basic sense, it lacks pretty much all of those features.
