A few things I wanted to figure out are : if something like a pipe bursts or a electirical fault occurs and you have to take down the wall, how do you go about repairing it, since the wall was designed by using a injection system. Would you just do it the normal way or have to get other special equipment to repair it? I love the idea of this, it turns everyone in the building industry into potential designers, you may lose the bricklayer but instead he would be the man who monitors the machine.

I really hope this vision will come to reality soon & mass produced. Think of the millions of homeless people who are living in poverty. If city developers build well planned 3D printed houses and cities for the masses - think of the enormous savings on property / housing prices for the people. The reason why we need a day job is because 30-40% of our salary is paid for housing loans. Hence, if 3D printed cities are well developed, price of houses can be reduced (but this requires great political will). Then, all of us will no longer be a slave to the banks paying mortgages for 30-40 years of our lives while working 10-12 hours a day (or more). Reduction in mortgage loan payment for an average household will mean MORE savings for education,healthcare, retirement and other expenses. Therefore, a loss of job (if any) would lead to less hardship for a household as you are paying less mortgage which is the biggest expense for any household. As a result, we no longer need to fear the loss of jobs in the property sector as less resources is required to pay monthly mortgages for an average family and other jobs will continually be created in other sectors in future.

pat raj The technology is actively used - in real life construction - in China. They printed some emergency housing and more recently a multi-family house. I think this technology is a way to make concrete construction much more affordable and usable instead of painful form work to cast concrete in place or heavy prefab elements that have to be transported by truck. Since the printer can in principle build any form, it will be up to engineers to find out if some form will hold up. The Iraninan builders were in fact much advanced: they used earth quake proof design already in the Middle Ages: most Iranian domes - the beautiful colored domes - are earthquake proof! They are all built as double shells so they have shear webs between the two shells. The technique of building domed hallways and rooms with at least one wall that goes up bit higher so the arched bricks can be leaned on it so the construction won't need any scaffolding, is ingenious and extremely beautify. The Iranians also developed the first gravity fed air-conditioning system with a tower that acts as wind scoop, guides the air down over a bed of rocks or water to cool the air and draws it into the living room by means of a domed roof with a hole in the center - completely simple and ingenious. They didn't whine about lack of work places from not needing wood structures. They created other jobs which society needed. I think that every technology has its enemies initially as yes, it will require rethinking and retooling and retraining workers for other jobs, but that problem existed many times and was overcome (think of coal fired locomotives, taken over by Diesel and electric. Think of horse drawn carriages taken over by self conducted cars. Think of coal mines taken over by oil wells. Think of brick layers overtaken by steel buildings and prefab wall panels. It takes retraining of workers, but there will be other jobs arising from eliminating some construction jobs. Not all jobs can be eliminated, as these printed houses also need windows and doors! which may still have to be hung by hand. But casting concrete isn't really such a great job and if the machine can do it, all the better. Besides, concrete needs no painting. How great - no flaking paint!

Brigitte Meier Assuming you're talking about WinSun, the company that made 10 homes in 24 hours, Khoshnevis actually has explained that they have copied his design. CEO Ma Yihe of WinSun actually visited Khoshnevis years ago in his lab and learned much about his process. Then Yihe turned around and started his own printing. Contour Crafting can be traced back to 1996, with Khoshnevis.

Nate Moore I think it's a stretch to say WinSun has copied his design, they are quite different. Khoshnevis is talking about a 3D printer to build entire houses, WinSun is essentially printing pieces which are transported and assembled on-site, modular in other words. Khoshnevis is talking about a portable light-weight printer, WinSun is using a huge fixed printer in a factory, it's 6.6m x 10m x 40m. Khoshnevis's idea for CC is much more complex and but will be amazing if he can get the funding and build the machine. WinSun is essentially using a much simpler model in the meantime. Happy that someone's doing it though!

This will not decrease the cost of building. I am a concrete contractor and know the industry rather well. Like when paving machines came out and can lay roads 10 times faster than manual labor. However, material costs will "suprisingly" go up accordingly and the "laborers" will turn into concrete plant operators or raw material distributors. So this will not put people out of work or make it less expensive to build. It will just have good quality control, thats all.

*Sign me up.* The Printer That Can Print A 2,500 Square Foot House In 20 Hours. We have seen huge advancements in 3D printing. We’ve even seen oversized wrenches printed that measure 1.2 meters in length. Now, we can print an entire 2,500 sqft house in 20 hours. In the TED Talk video, Behrokh Khoshnevis, a professor of Industrial & Systems Engineering at the University of Southern California (USC), demonstrates automated construction, using 3D printers to build an entire house in 20 hours. In manufacturing we use a process called CAD/CAM (computer-aided design / computer-aided manufacturing). 3D models are designed on a computer and then manufactured using CNC Machines or 3D printers. The design is manufactured into a physical object automatically, with instruction from 3D computer model to physical object without human interface. Automated construction basically scales up this process. The size of the 3D printer is large enough to construct walls by depositing concrete based material layer upon layer to build a wall. www.contourcrafting.org #futuretech. #constructiontechnology. #contourcrafting.

Most foundations crack. The reason the rest of the house doesn't is because there is some give between the different portions of the house, and when a wall does crack, the problem is more or less isolated. What do you think the odds are that a one piece, rigid house will settle evenly? Plus, there are all the problems Edison faced-it is damned near impossible to fix plumbing and electrical when all the walls are super strong concrete.

Certainly there is a great deal more research that needs to be done with large-scaled 3D printing. However it is notably faster than prefab and almost certainly uses less materials. The technique is also best suited, not for straight walls, but for organic construction with curves, domes, and arches where the shape itself is inherently strong and reinforcement is far less of a concern. A prefab dome is expensive. But with 3D printing the cost of the straight wall and the dome are the same.

Practically, this system won't have "minimal human involvement." For efficiency and quality control, you're still going to have a crew of guys for each machine feeding it concrete, transporting materials to the build site, double-checking its measurements, pre-install testing the house's electrical systems, and making sure the equipment doesn't break, clog, or go apeshit and flood an in-progress apartment with slurry. This isn't a colossal step away from modern crane-based prefab construction.
