3D homes should be more free-form and take advantage of the earth's thermal balance.
We could learn a lot from termites...

Barely a month ago, a 3D-printed house was listed for sale to the public for the first time in the U.S. Now, a small, 3D-printed community in Texas is following suit. Another, larger community in California is also in the works. In other words, 3D-printed real estate is taking off in a big way.

—” pre-pouring entire office buildings off site for at least a decade.”
Hollowcore slabs on a steel structure with precast exterior?
Still, need a topping on the floor? Pumped up?
The interior walls are still tin studs and drywall? CMU? ?
—”then do the whole routine over again the next work day.”
They add a floor a day, weather permitting? Low rise/mid rise?
Interesting. Thanks! Just ordered a X-Max to replace my XYZ-Pro so I can print Carbon Fiber Polycarbonate.
—”Unless it includes rebar, concrete is brittle”
There are many mechanical additives for concrete, not all of them can be pumped.
Yes, some of the fibers would protrude from the wall.
They could lay in durawall.
The concrete used on the pyramids, no rebar?
Still holding!
Decent of him.
There is a lot of dislike here about even the concept, but I think it may revolutionize construction. The amount of customization would be astonishing.
I think it is something to watch. It is in its infancy. I am an avid 3d printer, and I see a lot of potential.
I think many people see this the same way many people saw a Wright Brothers flyer back in 1905, and it was impossible for them to imagine a Boeing 747.
His boss said “He’s the hardest working kid I’ve ever known. Hire him.”
They bought him a brand new semi tractor and trailer

Shut way? Three houses?
Even if it's fiber reinforced?
—”All the structural walls are printed.’
How is the pour completed around plumbing and electrical services in the wall?
A photo at the link shows plumbing, electrical boxes, and romex in the wall.
The wall texture appears uninterrupted?
Listening to his old man paid off...
Me too. And you're right. 3d printed homes are in there infancy. We've not hit on the right materials just yet, IMO.
There's no reason the material used shouldn't provide insulation, non-cracking characteristics, and great strength. 3 printed structures should be the safest of all structures.
And we seriously do need to get away from the boxed, poverty look to free-form structures able to last centuries that take advantage of earth's thermal resource and blend in with nature.
Not so sure. Hearing rumblings from the left that concrete is environmentally harmful so Greenies will probably try to ban it. Plastic is out. Can’t harvest trees. Think we’ll all wind up living in canvass tents.
Yep, that is why they are opposing hydro power from a Canadian dam that is already built, Hydro Quebec. Fighting like mad to keep a power line from running through Maine to service them in Massachusetts. The evil power lines are supposedly going to destroy the view of the wester mountains, while there windmills have already destroyed the view in Eastern Maine.

The pyramid is compressive loads.
Sure did.
It’s kinda cool the way that works.
All of my kids are independent and on their own, but they have no problem calling us for advice.
The Australians did the old opal mines make great homes.
Beat me to it.
But someone might huff and puff and blow our houses down!
"Yo! Wolf Face!" 
I do not know about the topping - they cast the floor slabs off site, delivered by truck, and just dropped them into place.
As I recall, the interior walls were completely assembled and they had some clever ways to deal with wiring and pipes, which I do not recall at the moment.
I read the article maybe 5 years ago - everything in the building was pre-fabbed, perfectly measured, and set in place.
Seemed like a good idea that they could have been doing decades ago.
I am thinking maybe 20 floors. They were having problems trying to get permits, so the builder just said screw it, we will build the whole thing off site and just drop it into place.
I think the builder actually got R&D money from the government eventually.
I will search for the article and send you the link if I can find it.
