Future of Construction Process: 3D Concrete Printing

the pussies should PRINT those pipes already in the wall!

Rebar in the form of small steel rods (approximately the size of a normal wood nail - eg - just a few inches long) is used in Australia, and I've seen it in use on Grand Designs as well. All that's needed to make structural components would seem to be some kind of mini-rebar feed system, perhaps coupled with some compter smarty stuff so that the mini-bars are positioned in structurally useful ways.

So I'm curious as to where this is up to, I've read the exhibition flyer. But what I want to know, is how long until you are willing to build a house with this?

[animalnt]

would make more sense just to design the plastic mould, that way you can reinforce it, and make it quicker. Good idea though.

[thebigseahorse]

Thank you, yes you are quite correct. We live in amazing times if the world could come together as one then we would be almost there!

Om ah hum, Om mani padme hung.

Gratitude my friend.

[3goldy]

This IS A-mazing!

Can you also pring ANY ather metirial?

[elvide82]

Wrong way! The idea is nice, but the challenge of future buildings, is to have beautiful architectures using little energy energy and natural materials. So I don't think that concrete is a good solution.

[dreamerofhanuman]

@elvide82 Maybe they can use hempcrete. Have you heard of it?

[elvide82]

@dreamerofhanuman What a coincidence! I saw a house made with hempcrete just 2 days ago. It was the first time, I didn't know nothing about this technology before. From what I saw and touched I can say that hempcrete (blocks of hempcrete) is very light and not very resistant. Basecally it can't bear much weight, so it needs a supporting structure. Well I guess it is possible to print a monolithic nice shaped hempcrete structure and then to adapt a supporting wooden structure to it.

[dreamerofhanuman]

@elvide82 Lol thats funny. I just learned about hempcrete to. Yeah it does need a support structure though. I wonder if it can be incorporated somehow?

[hotfreshrider]

OK COMPUTER...

BUILD ME A HOUSE K THX

See also, the videos on "Contour crafting". People have been working on this idea for quite a few years now.

[Gilotopia]

Cement cures in a looong time. Doesn't that cause a problem with the object becoming very mushy and collapsing?

[Ardias000]

This work seems very similar to the contour crafting process by Behrokh Khoshnevis at the University of Southern California, have you been in contact with him for possible collaboration?

The Venus Project on action......Let´s change to a resource based economy..

[benreidnz]

Forget off-site construction: Just print the building on-site from the foundations upwards!

[copie692012]

It makes me think about the Venus Project from Jacque Fresco since I discovered ZEITGEIST ADDENDUM then ZEITGEIST MOVING FORWARD

[thebigseahorse]

Thank you for uploading this by the way.

[thebigseahorse]

The Venus Project . com and The Venus Project design .co.uk shows a very possible solution for what is possible for the entire world, if we can all agree on something for once.

[mquiroz90]

@thebigseahorse think that now new construction will come there be faster building and self building like be like 2 secs be done and tools can advance that we can still do things manually

[thebigseahorse]

@mquiroz90 Thank you, yes you are quite correct. We live in amazing times if the world could come together as one then we would be almost there!

[CarsonConcreteCorp]

Concrete is definitely the future of construction. Keep up the good work.

[kjelle90]

This idea is awesome. It makes construction of building houses a lot more efficient. But I have one question. What would be better for a wireless network? A house made of wood or conctrete?

Take your time for a response

See ya!

[KlunkerRider]

What they making is essentially a custom made fancy shaped concrete block. Steel rebar would still need to be placed by hand and mortered in place. Still this opens a lot of new intriging ideas, custom shaped blocks would be possible. but regarding the suggestion about placing pipes inside the block structure? what happens when it leaks? Water saturated concrete is not a good situation. place your pipes/duct/conduits where its readily accessable. good luck with it.

[concreteprinting]

@KlunkerRider Thank you for the comments. Eliminating rebar is another option we are looking at now. Regarding the easily accessible utility holes and pipes, yes you are quite right. We will keep in mind your comments. :0)

[cola2k3]

@concreteprinting You want to eliminate rebar? Are any of you engineers? Concrete is a terrible material in tension. That is why they have rebar installed. Elimination of it would create rapid failure in a worst case scenario.

[ColdT3a]

@cola2k3 I think the comment was focused more on using alternatives which would be easier to use in an automated process. Fiber-Reinforced Plastic is one such alternative.

[videowatchaccount]

@concreteprinting How much can you get away with with a ferrocrete mix?

[manofsan]

@concreteprinting,

Why not consider some kind of enhanced fiber-reinforced concrete as an alternative to rebar? The goal of rebar reinforcement is to add stiffness, is it not? In which case, the right kind of fiber-reinforced could add stiffness to the walls/structures in a more uniform way than rebar could.

[3goldy]

@KlunkerRider "by hand" is EXACTLY what 3d printing is eliminating.

as time goes by; 3d printing WILL BE more accurate & reliable.

[KlunkerRider]

@3goldy my concern wasn't the issue of assembly, it was the notion of placing utility pipes (water, drains) inside the block cavity itself, if the pipes leak or break the only way to repair them would be to physically break open the concrete wall to get access, and that would be prohibitively expensive and water saturation is potentially catastrophic to the building structure. Those were my main concerns. I still say good luck with it and hope they succeed, its interesting stuff.

[3goldy]

@KlunkerRider Today it is possible to claculate the maximum pressure needed for the pipe.

It's also possible to to design a service door.

[KlunkerRider]

@3goldy true but stresses, defects and/or bad installation can result in leaks and breakages. You just dont want to place pipes where you cannot get your hands around it. I inspected a bldg built in the 1920's where the pipes were cast into the concrete structure of the building, bad mistake as the concrete was damaged and most of the leaks were totally inaccessable. The only solution was to totally redo the plumbing system in new chases at great expense, dont "build in" a problem you can avoid

[3goldy]

@KlunkerRider I'm sure that in the future it will be possible to cast all ingredients at the same; 'rocks' to the cement & iron the the cast: as if it is a traditional building.

[davidadunade]

excellent work. my thesis is on prefab systems and lean construction. please send me more info to davidadunade@yahoo.com for collaborative research work. thank you.

[usernameunvalidhuh]

all the best and cheers!!!!

[faisaldurr]

Wow! Proud of seeing my collegues working on such ambitious project. It was fun seeing Mr. Buswell And Mr Austin too. All the very best guys!
