Thank you Belinda...for the accumulated information

first real explanation of why 3d printed concrete constructions make sense that I found, thank you

Excellent clear presentation and simple clear explanation - thanks

Great video with a thorough explanation In my school, I am currently working on developing a new mechanism of simultaneously reinforcing printed concrete (vertically) while printing.

Thanks a lot Omar! Would love to see your work.

ONE 1st National Seminar in Nov 2017 on 3D printing in CIVIL Engineering was conducted and I also represented India in a 1st int. Conference on 3DCP held at Australia 2018. I find that basics of 3D printing with concrete mix has been explained very well by you now, I wish this vedio was then available to the participents of my conducted National Seminar at AKGEC, held on 15-16 th July 2018 .Congratulations-Prof K Kamal

Really Informative. It would be great if you post more videos on 3d printed materials used in construction and thank you for this amazing video.

Awesome! I would love to implement some of these ideas in my little world.

Thanks for that excellent explanation. I would love to see this technology help people and countries that suffer from problems with homelessness, refugee housing and people who many need emergency housing due to natural disasters.

Thanks a lot!

Very informative piece. It seems as though this tech just might be starting to catch on in wider use. With builders like ICON in Texas developing their own in-house printers and acting as a builder in a vertical integration while also being able to conquer regulatory hurdles, its only a matter of time before we see a paradigm shift in construction using this tech. This is especially true today as our industry is confronting runaway material costs and an acute skilled labor shortage which is unlikely to improve any time soon. I really do believe, like you stated, that additive construction is the future and may very soon be the now. I work for one of the top 10 residential homebuilders in the US and I cannot wait until my industry can break its old habits and embrace methods like this. If we fail to do so, we will be left to the history books I fear! Please make more content that explores the emerging world of additive and modular construction tech!

I rarely comment on videos but this was just really good! Really informative.

@@BelindaCarr I have a lot of questions regarding 3-D printed concrete homes. I have not found any ACTUAL examples of homes built this way. Does this method also install roofs, doors, windows, HVAC, plumbing, electrical, stairs etc...? From what I can see 3-D printing can ONLY make a partial shell (no roof) of a home. How about the physical footprint of the 3-D printer itself? There would have to be room on the jobsite to accommodate some kind of gantry system that, by necessity, would be larger than the house itself. In urban and suburban areas you may only have small building lots. I would like to see an actual REAL LIFE example of a 3-D house being made and the ACTUAL TOTAL COST. I smell a political government program SCAM to fleece the tax payer. This makes shipping container homes seem reasonable.

Great insights, thanks.

Great job on the video...very informative! I would love to know your thoughts on building materials made out of recycled plastics...maybe even plastic pulled from the ocean.

It looks very interesting

If I might ask, what's allowing the individual layers to stick to eachother?

Can you make any recommendations for large scale construction 3D printers for large buildings? Anything you may know would be great 😊

Is rebar still needed with 3d concrete? If so, how are the various printers coping with this requirements ?

Very nice video 👍. I like to see more organic 3d printer homes with gardens.

Just saw your video debunking 3d concrete bs. You linked it to here. Thanks. Keep up the good work.

I'd love to do this, i wonder what hurdles there are to meet Australian building standards.

This was really helpful.I just had a doubt.Do you think this concrete can be used to print complex patterns like a honeycomb?

It's really an innovative technology. Thanks India is adopting faster. Your video is very informative.

what is added to the concrete to make it set so fast? is it added during the mixing or just before it gets to the nozzle?

The 3-D houses I have seen have been rather small ones. Is it possible and have they begun printing large homes and other buildings?

Good presentation 👌👌👌

Hi We are working on 3D printing pilot project. We are in the process of developing a suitable ink for the purpose. I am glad I found your video which is so informative. It will be of great support if you can guide us more on this.

This is excellent, thanks. I'd like to see how industrial scale 3d printing might work, for commercial or industrial facilities. It's promising and interesting. This how looks really beautiful.

Whats the simplest way to integrate steel reinforcements into 3D-printed buildings? What about insulation? And is it more efficient to print the whole wall structure or just the outer shell and filling it up with reinforcments and conventional concrete? Nice content btw :)

@hellosoll2953

To integrate steel reinforcement into 3D-printed building could be made possible if you print the outline of the wall first, add the rebar, then cast it. With this method, the printed wall outline acts as the formwork for the structure. This would be case if you need the reinforcement in the design. 3DCP offers flexibility in terms of the width of the extruded concrete and the material you want to print (higher strength concrete). With that in mind, you may want to consider designing building with load bearing wall. About the insulation, you can produce double wall for the building and apply the insulation in the void.

Hi Belinda, Is this classified as a geopolymer cement? What is the chemistry of Durham's water putty, we don't have it in the UK, but it might be produced under another name?

Can you trowel it as it pours to smooth the walls?

I thank you for sharing this video. I would like to see information on strength testing of the 3D concrete. Perhaps there are too many planes of potential failure by placing this way.

Does the 3d printed concrete with carbon fiber have an enough ability to handle the loading of tall building construction?

Great information. I dream of ideas of art with concrete. In addition, building ideas are greatly interesting as well. New technology for now with 3D printing. I have ideas of cement structures, for gardens, art, and building facade, ornamentals. Old tech work by hand. I dream of the vast possibilities, and I'm nothing without funding, money does make huge impacts. Thank you for your informative video.

I'm looking forward to see what people come up with to get steeper overhang angles. With plastic, you an easily do 45° overhangs, but it looks like concrete needs to be much more vertical.

👌👌👌 Thanks

How is the carbon footprint of concrete used in 3D printing vs traditional forms of concrete?

Thanks Belinda: I’m still not grasping exactly how tensile strength is being introduced into the robotic fabrication process. One might argue that factory-based fabrication of prestressed double-tee floor beams, commonly used in parking garage construction, is already “robotic” to a considerable degree. In my region, in common building construction, concrete is primarily used for foundations and floors, is reinforced with steel and is almost never seen. Critical yet fundamentally prosaic from the standpoint of architectural expression.

Have just come accross this . Last year I attended a a presentation by the founder of Trik Her product adds value to drone surveying by using data from the images taken to produce models The same approach has potential to drive 3d printing so that a replacement property had the same edifices as one that had reached the end of its useful life Townscape retention could help meet the concerns of those opposed to change in the character of their community

Love your videos. Do you know is this type of technology is being considered for production of habitats for moon or mats colonization? It seems like it could be adapted for robotic building before humans actually set foot on a different planet.

Hard to say if it will be worthwhile. It has been taking some time to develop so there are still some kinks to be worked out. In time, it will likely be very cost effective in the long run as soon as people can figure out how to do it.

Which Concrete is stronger??

How much coast building 3 D printed 2 bedroom with 2 bath ?

How strong this 3d printed house is ? What happens to the 3d house if somone throws a stone to the house wall. Does 3d wall handles Mr. ROCK's punch ? ☺️😊

3D layering effect can be quite organic (if done tastefully), but Gaudi will just cover it up with tiles. The biggest problem is fitting windows or 2nd floor, so most 3d printed house end up being a dome.

This would be awesome in the theming industry

I am very interested in this technology. I understand that it is typically much cheaper to build homes this way due to decreased costs in labor and waste. My only concern is with issues such as air quality and comfort level of occupants within the home with regard to heating and cooling requirements.

Hi Belinda, traditionally concrete is reinforced with steel (re-bar). Are you saying that the carbon fibre additive to 3D printed concrete is a replacement for steel reinforcement? I'm wondering what the differences are in terms of structural rigitidy and durability between traditional steel reinforced concrete and this new type of concrete composition. If the carbon fibre reinforced concrete is an adequate replacement for re-barred concrete, should we see a transition to this composition of concrete even for companies using traditional methods?

A well thought out 3D printed house is simply a way to get the most Bang for the Buck.

This was very interesting. Though, you'd think someone would come up with a knife that would follow behind and cut the layer smooth. Just a thought. I guess you'd have to figure out what the hot knife would be for that butter. Dunno

Hi ... thoughts on aircrete / foamcrete? Aircrete Harry has an interesting KZread channel

Each layer would need to cure before the next layer was put on top of it, so that the weight of the layers didn't crush the ones below. This means very fast cure times, like under a minute. At the same time, if it cures before it leaves the nozzle, it would jam the machine. Maybe a two part epoxy concrete that is mixed in the nozzle. Both parts would have to be pumped to the nozzle separately.

@@teslastones How fast setting? And how strong? Say you mix it thirty minutes before it is extruded onto the wall. Then the next layer comes around and is laid down on top of it one minute later. You would need a setting time no less that thirty minutes and no more than thirty-one minutes. That is a very small window to hit. Even if you hit that narrow window, how many layers can it support before it cures?

Michael Deering all of those parameters are engineer-able with the right binder Your input to this young lady are true only if you are using OPC Set times of the right binder ( cement ) for the job can be a matter of seconds-- or days if such is needed As stated earlier, cure time is also adjustable. Usually I like full strength within a few hours if I’m fast-tracking Since there is no shrinkage ( the number one cause of cracking in OPC ) one does not have to worry so much about fast set There is no curing procedure as with OPC

"It's to be expected, it's a new technology, the costs will continue to go down with time" - every time I hear this statement it makes me doubt the viability of whatever product is being discussed - I've seen so many people misuse this for bust technologies that are inherently flawed, for example, solar roadways.

I am interested in constructing a 3D printed house in Baja California, Mexico. I need an architect. I have a piece of property 450 square meters. Besides the basic structure, the print should include duct work, cableways, water ways, solar panel supports, and tanks for water, black, grey, and potable.

3:00 Form boards aren't always wasted though. You can reuse just about all of it and most concrete guys I know do. I mean, you only get a half dozen, maybe a dozen pours out of them usually before you most guys replace them, but still. I've actually thought about designing a modular fiberglass or plastic/epoxy form board system that you could extend in length and snap/pop together and stack for taller footers and slabs on sloped grade etc. Could even do nice texture on it so exposed footer looks good. Don't steal my idea now.

Most/all builders don't use wood forms for walls. They use reusable metal forms that you can rent and they drop them off in a container like a large dumpster. Takes a few days to bolt together then one day to pour. They are usually patterned like brick but any pattern is possible. I don't see any way 3d printing cement walls can beat that speed, price or simplicity.

As the sole and only 3d print concrete license owner, that covers all 3d printers, its sad to see piracy already creeping into this sector. The human manual labour construction companies are now facing a new challenge of pirate 3d print companies making commercial gain on extremely low cost prints achieved by not paying royalties, piracy. Steeling money, jobs and businesses from the wider comunity in such a new sector is very disapointing. All manual labour construction companies and comunity should be asking all 3d print sellers making commercial gain did they license check and pay the royalties, no matter where the stl came from or who drew it. To not is piracy. And this fast growing competition to the construction sector and job market has already a lack of checks and ballances. Pirate farms can and are being close for non payment of royalties so i urge all companies espesially manual human construction firms to check all commercial gain being made on 3d printing concrete. As it stands this is one sector of 3d printing that requires pulling into line. As its growing fast and so are the losses. I can easly confirm wether royalties are being paid or not. Its been revieled to me in the last few days the rapidly growing scale of companies comming on line making commercial gain and the scale of infringments and non royalty payments. Please all assistance apreciated. Thank you.
