Half the cost sure as a marketing gimic.

IRVING KAHN
by Samuel Tailor Coolman

In Levittown did Irving Kahn
A lovely Cape Cod house decree:
Where Alf, the Sacred Neuman dwelt,
And Nick Fazool and Olaf Svelt.
And even Sean McGee.

There, fifty feet of crabgrass ground
With picket fence were girdled round.
A place for little Milt to play,
A port for Irving's Chevrolet.

But just one thing is not the very best,
you can't tell Irving's place from all the rest!"

With thanks to Mad Magazine

300K is half the cost? Can I get half the cost of that instead? Also, I would buy one.

But you'd have to live in Levittown.

I know building materials are up, but how does a 1,500 sq ft. House cost $600k to build?

Would buy one in a moment. Edison wanted to do concrete houses back in the day because they were cheap, economical, and most importantly, fire proof.

California should be taking note and buying from the company in bulk.

How the heck do you insulate them? Also is the concrete reinforced in anyway? I would think a precast system would be better than 3d printing.

That's pretty cool. I'd feel pretty secure in an all concrete house. Seems like most new construction is made of construction farking paper and bubble gum.

Build no.  Land cost.  Usual construction will cost you 125 a sq.  The rest is land.

But then you'd have to admit you were basically living in a utility vault.

Nice!  Those things are sturdy and really rock!

It's disappointing to see that in the 10 or so years since I first saw 3D home printing tech that it hasn't improved.  You've already got automation there that's following a motion plan... how hard is it to place 2 or more positionable smoothing paddles near the nozzle to knock down that nasty extrusion splooge line?  Heck, add a little rotatory motion to the paddles and give it a robo-stucco textured look.

Because these people are builders and engineers, not artists.

That's why it will fail. People need to desire what you have for sale, not settle for what you have for sale.

"So after careful review of my finances, I've determined I can afford an 11 Sq ft house. Lets build this thing! "

Theres nothing as warm and environmentally friendly as a concrete home.  Think of all the home improvement projects you can do with a simple jackhammer and ramjet nailer. The beautiful textured outside is good for shedding heat in the winter, while learning about the thermal expansion properties of the water as it freezes between the ripples. Pointing? More like pointless, right?

FTA "We started making small, desktop 3D printers and came up with the idea that we needed to disrupt the housing market and the construction industry,"

This tech has been around a while https://en.wikipedia.org/wiki/Constru​c​tion_3D_printing.

Interesting idea

/-I was thinking it needed siding but some texture in the concrete might do the job

FWIW, most or all of the homes in Iceland, not known for its tropical climate, are concrete construction. There are ways to deal with the insulation problems.

Manipulators of several types, maybe even interchangeable tools, would be useful near the nozzle or even on a independent seperate gantry.  I imagine hanger pins could be inserted in the extrusion once the mix has set enough to hold them.  Or they could be part of a bracket placed ahead of the nozzle and cemented in place at pre-planned intervals.

Pins/brackets that would extend outside or inside as needed to be hangers for insulation, siding, drywall or similar.

The uncovered cement walls on the interior made the house sound like a damned cave in the video.  Way more so than a regular empty dry-walled house.  Very few people would put up with that hideous echo.
