A company in China has unveiled a house created entirely though a 3D-printer.
Experts took part in the creation of the building which was printed in one go at a construction site in the Tongzhou district of Beijing.
It took just 45 days for the project to be completed.
The entire large villa was printed in one go without being cut and then put together using a number of different pieces.
Construction firm Beijing Huashang Tengda worked to build the 4,305 square foot home which stands at two storeys tall.
The company claims that the walls are as thick as 8 feet....

I was going to ask, How do they print re-bar?
But then I saw the line about 8-foot thick walls, and thought that maybe they really didn’t need re-bar. But then the fifth photo in the article shows a forest of re-bar, clearly not “printed”.
In the photos there’s no evidence of 8-foot thick walls, so I’m thinking that “8 inches” got lost in the translation. From the pictures, it seems like the printing method is to lay down 8-inch wide, 2-3 inch thick layers of wet concrete along the perimeter of the house. It took 45 days because each layer had to cure before the next one could be laid down. The “printer” would be like a big pastry bag controlled by a robotic crane.
Funny :)
B the time it got back around finishing a layer it may have been cured.
Will all the house wiring conduit and boxes and pipes be visible since the walls are solid?
I think prefab sectiomal houses go up faster than 45 days.
So basically they designed a computerized concrete pouring machine to make a shell. Interesting concept but that’s about all.
Notice there is no finish work inside (insulation, wiring, plumbing, etc.) which is a whole other story to complete.
I’d rather take a modular house completed on a production line in about a couple of days, transport to site, drop on a prefab foundation bolted together in about 4-6 hours.
One job I was on was a house of 3900 sq. feet with 9 foot ceilings and 4 sections/2 stories. Prefab concrete foundation assembled on site in 5 hrs. on compressed gravel footings. The foundation also had 3/4 foam insulation built in and the option to add 6 more inches if needed in structural bays. Also already firred out for sheetrock.
Install a boiler and water tank, tie in waste and plumbing lines and electric and you are done in under two weeks.
Any idea how much one of these house would cost, say, in Detroit?
“But how will it do in an earthquake?”
I find no reason, why the latest earthquake safety measures can not be engineered and built into the design.
Materials, sheer reinforcements, flex, footings, etc.
A buck ninety-eight.
But you have to pay the back taxes, which comes to twenty-seven million, four hundred thousand, thirty-three dollars.
Uh, no. There are many different types of 3D printers. Most do NOT involve lasers. And certainly not "human tissue", since those involve whole cells. Try zapping a living cell with a laser, and you get a puff of smoke, not a 3D structure.
Unless they have a video, I say the baloney is 8ft thick.
If you look at the actual pictures (not the drawings) it appears that all that was done with a “3-D printer” was deposit concrete mix. All the reinforcing bar appears to be hand built, the windows look as they were installed by hand, and the roof looks hand built. It seems to me, that the “3-D printer” was simply a controlled direction cement pump.
It’s not that the printer is big, it’s the continuous feed concrete that is the challenge. This has been done elsewhere.
That’s all well if that’s the case I’ll take two.
