How long does it take to build a 3D-printed house?

Alquist used a massive 3D printer to create the structure of the home out of concrete, rather than wood and other traditional materials. The process took just 28 hours — the typical Habitat for Humanity house takes at least four weeks to construct — and it cut building costs by 15% per square foot.

Been looking into this tech for Anon-Island.

I have a fren, he is an engineer, that built their entire house in TN out of concrete! The entire thing floors walls all of it. Sold it when they divorced recently.
About 4k sq ft. and it was amazing!
There are also so personal taste decorating differences for instance ya cant just put a pic on the wall with a tiny nail or screw.
Point being the best ppl to confer with might be ones that have lived in one.
Of course over the years concrete also has some issues and the concrete must be the precise consistency to work out without early yrs cracking.
Is there a particular type or consistency that is more hurricane proof?
Nana thinks the 3d printing of homes is awesome.
We are going to only be limited by our own imaginations soon I hope.

We need to figure out hiw the romans made their concrete. Their's gets stronger over time. Total game changer

Wow did not know that!

Nana, look at my answer to the post above - it may not help unless you can find a substitute for volcanic ash, but it should exaplain

Hun sorry but I cant see your comments to other ppl.

I'm guessin' this is my reply you're taking about

"The Roman created Concrete with Volcanic Ashe - Pozzolana
And the ash allowed them to create concrete piers on water, etc; it's one reason why so much stands today

They would occasionally add (small) clay jugs to help displace the concrete to create domes link in the Pantheon

But the concrete wasn't earthquake proof, or allowed some give
till the Byzantines added Lime to the concrete during or before Theodosius II "

Thank you for letting me know which one. Thanks for sharing that. Do you have some more info on it?

Here are a few links on the concrete
