timebandit Posted December 12, 2013 Share Posted December 12, 2013 (edited) Can be built quicker than nimbys making the protest placards. 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.

MartinE Posted December 12, 2013 Share Posted December 12, 2013 Extruded plastic house*- now that would be progress. Patch the roof with a shopping bag and a hair dryer. Melt in extra windows in summer and block up in winter. *not recommended for sunny days. Quote Link to comment Share on other sites More sharing options...

The owner will die of cancer - but not in debt, which is the most important thing. The printers spray concrete, apparently. Quote Link to comment Share on other sites More sharing options...

I think you could build the same thing just as quick if not quicker using prefabricated shuttering and a standard concrete pump The only advantage would be the ease at which you could change the design of what`s built Edited December 12, 2013 by long time lurking Quote Link to comment Share on other sites More sharing options...
lebouche Posted December 12, 2013 Share Posted December 12, 2013 I think you could build the same thing just as quick if not quicker using prefabricated shuttering and a standard concrete pump I watched a vid about this a while back. The walls are built with cavities and are v strong, light and provide great insulation. Also you can build any shape including curved buildings, copy old style buildings. The limit is practically your imagination. Quote Link to comment Share on other sites More sharing options...

The limit is practically your imagination. The advantage as far as I can see is the ability to change the design of what`s built at the touch of a button I would be very interested to know what sort of concrete /cement it uses as it can`t be standard if its capable of building a two story house in 24 hours due to the cure time need to support the weights involved Quote Link to comment Share on other sites More sharing options...

Ultimately plumbing, electrical wiring, and even certain internal fittings and wall colour can be fabricated during the 'printing' process.

okaycuckoo Posted December 13, 2013 Share Posted December 13, 2013 How dose it PRINT the electrics/pluming ? all I have ever seen is the finished walls with ressese`s in them ready for the elc/plum to be installed into to manualy that could easly be applyed to shuttering. No idea. If possible, awesome. But central gubmint will make it non-possible, unless at a huge price. Quote Link to comment Share on other sites More sharing options...

To me it's fascinating to see this technology coming to the fore now. In the 1990s I wrote several investment notes covering Virtual Reality systems and consulted to a couple of companies in that market. Fortunately I was on the right side – I predicted that the likes of Virtuality, Division and Superscape would fail (although that was largely because their management was so poor – I had great belief in the ultimate penetration of the technology, and that view hasn't changed). At that time I also became aware of the emergent 3D printing industry and when I told my friends and colleagues about it I was just laughed at. It's a sobering lesson that it's taken close to 20 years for both of these technologies to reach mainstream consciousness. In fact I'm not sure that VR is really there yet, but the recent developments with the Oculus Rift (and especially John Carmack moving from id Software to become Chief Technology Officer) suggest that Joe Public will be aware of it in the not-so-distant future.

Andy T Posted December 13, 2013 Share Posted December 13, 2013 Nice idea but concrete (as I know it) isn't very strong in tension/twist without steel reinforcement, especially in thin wall sections with changes of direction and floors etc. Start adding steel rebar in there and you've got a load of labour involved in setting it out. Think you'd end up having additional insulation to the walls as well. Quote Link to comment Share on other sites More sharing options...
Bloo Loo Posted December 13, 2013 Share Posted December 13, 2013 we already make houses in this way. we just dont use a machine to do it. we stack bricks on a concrete base and build the entire frame first..then we stack the timbers in and floors from the ground up. Question...wouldnt these concrete shells be similar to the unmortgageable "unconventionally built half concrete buildings we have dotted around?

What you see in the video is nothing more than a scaled up CNC router /engraver/plasma cutter with a hose/concrete pump attached in place of a cutting tool This technology has been about for the best part of two decades and is a world apart from multi media 3d printers Quote Link to comment Share on other sites More sharing options...
billybong Posted December 13, 2013 Share Posted December 13, 2013 (edited) It might well be able to build the shell skins "in 24 hours" (the shell skins to include the internal walls as well as the external cavity walls). That's not much of an improvement on current methods as just building the shell skins can be done quite quickly already. Maybe not so much in the UK but overseas there have been demonstrations of extremely rapid construction by manual or by prefabrication methods. Is it much cheaper than current methods seeing as so much cheap labour is available and likely more on its way to the UK in January. So it doesn't seem much quicker or much cheaper - in fact at the moment it's likely to be more expensive due to it being new construction technology. It's interesting news of course as it adds another potential method of construction to the existing methods but like so many of these construction revelations about to revolutionise house building there's a way to go even if the idea gains momentum. It have little or no impact on the current UK house price bubble but if it's worked on it might well start to have some impact at some time to come. In the fullness of time (and that's potentially a very long time) the idea (3 D printing of housing/construction) will likely have a major impact - maybe not in the UK though seeing how hidebound UK housing is by other factors.

The UK are very good at it and increasingly skilled up thanks to the Tunnelling Academy. Quote Link to comment Share on other sites More sharing options...
