The 3D printer that can build a house in 24 hours
MSN's Innovation ^ | November 20, 2013 | Mark Hattersley

Posted on 01/08/2014 9:51:31 PM PST by 2ndDivisionVet

The University of Southern California is testing a giant 3D printer that could be used to build a whole house in under 24 hours.

Professor Behrokh Khoshnevis has designed the giant robot that replaces construction workers with a nozzle on a gantry, this squirts out concrete and can quickly build a home according to a computer pattern. It is “basically scaling up 3D printing to the scale of building,” says Khoshnevis. The technology, known as Contour Crafting, could revolutionise the construction industry.

The affordable home?

Contour Crafting could slash the cost of home-owning, making it possible for millions of displaced people to get on the property ladder. It could even be used in disaster relief areas to build emergency and replacement housing. For example, after an event such as Typhoon Haiyan in the Philippines, which has displaced almost 600,000 people, Contour Crafting could be used to build replacement homes quickly.

It could be used to create high-quality shelter for people currently living in desperate conditions. “At the dawn of the 21st century [slums] are the condition of shelter for nearly one billion people in our world,” says Khoshnevis, “These buildings are breeding grounds for disease a problem of conventional construction which is slow, labour intensive and inefficient.”

As Khoshnevis points out, if you look around you pretty much everything is made automatically these days – “your shoes, your clothes, home appliances, your car. The only thing that is still built by hand are these buildings.”(continued)

Yup

No reason it can’t work

Few details worked out, presto

New house

Have seen some amazing examples in my own industry

The more expensive the operations for building (and the wealthier the builders), the more expensive the products will be regardless of averaged, long-term costs. So the robot can build concrete structures. Where are the many other materials and technologies that go into a building?

Per square foot, a knowledgeable and practiced owner-builder can build a small house very quickly and for very little cost—very little as compared to an operation headed by a builder, who sits on his or her rear end giving orders. What will the cost be for buying, transporting and using the gigantic robot? Will it be transported and used in remote areas on the Rocky Mountains or more likely for building in the dangerous urban and suburban areas of the near future?

It’ll be a bigger problem when we don’t need so many American construction workers... That is... Fewer workers overall.

People blame China for taking jobs when it’s really not the case. Automation has taken more jobs than China ever will. Today’s production line requires just few people to manage.

If it 3D prints concrete, the resulting structure ain’t gonna be structurally sound without steel reinforcement to resist tension loads (concrete is great in compression, close to nonexistent in tension). How are you gonna 3D print steel bars into the pour? If you still have to do place those and tie/weld them together manually, then what did you gain with the 3D printing?

Concrete can also be fiber reenforced. It’s possible that formulations that can survive a major ‘quake can be made without rebar.

Well, Concrete is a very "plastic" building material.

This could go well, depending.

The thing prints the outer walls out of concrete, standing up in place, and then fills them in. I think humans would have to step in and put the rebar in before it is filled, unless they make a robot to do that job too.

Regular doors and windows. Humans come along and install them later. They’re just talking about printing the “shell” of the house, not all the fittings.

The conditions will dictate whether or not this machine or whether more conventional methods will be needed. I don’t know why this thing couldn’t come up with some molds for segments of houses, and only the molds and the materials to be poured into the molds need be taken to the building site. If level ground or conventional foundations are feasible, then that might be all we need. Maybe the machine could come up with custom molds for foundations to be set in uneven ground.

There’s no reason all the architecture has to be done from scratch at the site; it could draw upon design libraries. Kind of the Ikea of houses.

The machine could, however, do all the engineering calculations required to confirm that yes, the building will remain sound in the conditions it is expected to meet.

Yeah right, a giant concrete squirting robot is going build a house in less than 24 hours. Maybe it is possible with some other kind of magical material, perhaps the same stuff that keeps Pelosi’s face from slumping off.

So who puts in the electrical, plumbing, heat/AC, doors, windows, etc? I am imagining electric wires strung on hooks across all the walls. And concrete floors.... ouch! What will anchor it to the ground? Will it begin to slide when the ground around it turns to mud in a storm? Will the roof be concrete too?

That 24-hour-house will still need months of work to be livable.

Yep, won’t be long and the construction trades will be a thing of the past thanks to technology. More people unemployed. But then, it will take one or two people to operate the new equipment.

I'm not sure if you were being sarcastic. China already has entire cities that they built over the last couple of decades which are empty and rotting.

I see no forms.

I see no provision for maintaining the structural integrity during the 28 days required for the portland cement concrete to cure to full strength.

In short, the material selected is not suitable for the purpose intended

The concrete walls are hollow with an insulating filler. It would probably be possible to put the wiring and plumbing in there during construction. You simply put an aluminium utility run, with an access panel, in the wall, and and the printer prints over it.
The technology is not mature, but it is interesting and has a lot of potential. The houses in the pictures were butt-ugly, though.

This is one step above adobe, essentially. Not sure you could install rebar by deposition.

While I agree that deposition construction is great, not everything can be built by deposition.

It’s a question of materials. It doesn’t have to be concrete, or the same concrete we have now. Some sort of composite, or combination of materials from cements, to plastics, cellulose, metals... Carbon, glass... Who knows? All sorts of thinks might make for an excellent structure.
