@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.

It can even be stronger depending on the mixture.

These can easily be deployed in poor countries to print houses. The best part in my opinion is the lack of a need for any concrete. These machines can print houses with nothing but dirt and water. For those of you that want the machine to build bigger perfect homes complete with duct work, electrical, and wiring that might not sound great, but for homeless people in poverty stricken countries that's a win.

Not to mention a lot of that can be added afterward as well. It would be really interesting to see the cost per sqft of this vs "traditional" housing.

When you look at the actual cost of traditional housing in impoverished countries, I doubt this is any cheaper, if it's even close to as cheap. And of course, land is the real cost anywhere you are.

Not really. In many places land is effectively free. Even within the EU there are countries with zero cost land.

Yall are all missing another critical component here to Mars. It has to be somewhere above 40 degrees F to properly set concrete. It may get to 70 degrees on a summer day on Mars, but you better be hoping for a heat wave or something.

Concrete mix is a far cry form dirt and water.
