Pumicecrete is by far the best building material on the planet Pumicecrete is a mixture of pumice cement and water mixed and poured into a set of reusable forms walls are poured from 12"to 24" thick pumicecrete is fireproof termite proof rust rot and mold proof and has a high R value and good sound attenuation solid poured walls means no critters can live in your walls Pumicecrete can be built for a fraction of the cost and time and is perfect for automation
Liquid nails is better, every job I install floors on the contractor has it holding most of the building together and filling all the gaps so obviously it's the best material. Or....maybe the company I subcontract through sucks?🤔
Got Real!! 12. Thermal Bridging. 13. Moisture Control It can all get better by designing machines to make exactly what wall/building assemblies should be, rather than tweaking wall/building design to match what existing 3D printers already do. Imagination required!
It strikes me that the real future of 3D printed houses is somewhere in the middle-whereby the houses are not prnted on site, but in a factory-much in the manner of how typical pre-fabricated timber houses are built-in purpose-built factories, but in (the fewest-possible number of) easily assembled *segments* that are trucked to site and craned-in. (Thoughts?)
@@danohanlon8316 This brings up all the issues of precast concrete, that are very significant cost problems, especially for residential. More challenges for structural, utilities, precision, fit and finish, a need for heavy equipment, higher insurance costs...
@@SpaceCrete I hear you. But I’m really hinting at a marriage of both concepts, whereby the notion of digitally PRE-printed concrete *modules* display at least the potential to eliminate many of the problems of reinforced concrete, such as formwork. Can’t prove it; I just see it. (Maybe!)
I know this is in it's infancy stage and later on issues can be addressed. That said, you'd have to take into account the environment, climate, weather, fault zones, flooding zones and so on. So, building these homes in tornado alley would have to be different from one built in an environment of heavy snowfall. It will be interesting to see how this progresses.
Repairability. In a metal framed structure or wood framed home any damaged components can be repaired or replaced fairly easily without lasting damage, but every cut into concrete permanently reduces it's strength. Locality, you touched on the "just add water" bit, but it goes even beyond that. The availability of cement ready aggregates are not universal... the potential cost of transporting tons of minerals will add up very quickly. Also, cement walls may be great for a temperate and dry location, but places which are extra cold or wet.... not so much.
Thank you for this. I am a consumer and highly motivated to build a 3D printed home in the Pacific North West of the US for myself. I am in the very early stages of this, just working on the idea of it. It is really difficult for consumers to get any usable info, such as pricing, or where to start. I realize a lot of this is similar to building any home, lot prep, hiring an architect, locating a contractor. The newness of 3D printing adds a wrinkle. Will banks write a construction loan for such a project? Are there 3D printer contractors within Washington State? How to find the architect who can think outside the box, but without spending a fortune. My project will be quite modest, a single level 1,200 to 1,400 square foot home with one bathroom, one bedroom, one closet, and the rest will be open plan. So your busting some of these myths is helping a lot. I calculate it will take me 12 to 18 months to get this done from start to finish. I will keep you posted on my progress and share any insights that might help others. BTW, I do have a background in construction and in real estate but I am trying to retire so not able to do much of the work myself.
These homes will be most valuable as “ neighborhood “ projects as opposed to single home construction. Hopefully the larger scale of neighborhood/ subdivision projects can eventually underwrite transportation costs for single or smaller projects.
I’m for advancing the development of 3D printed homes but at the same time I never understood why they don’t use CMU block to build homes. Not only is it a very well understood construction method but the blocks are made in a controlled environment ensuring quality control of not only the mix but also consistent density of the finished product. CMU also has a consistent flat surface allowing other materials like insulation board, hardy board or other finishes can more easily be applied. As someone with a FDM printer at home I’d be worried about layer adhesion, consistent density and repair methods of poor quality sections.
Unless you are talking about something different, here in South Florida, most homes appear to be built of concrete block. My house, built in 1959, is concrete block so it's been around for a long time. There are a lot of commercial projects going on that use tilt wall construction. To me, that makes more sense than printing.
@@rogermccaslin5963 Older South Florida building codes required that exterior walls be made of 8 inch CMU's for hurricane tolerance. They also required tie straps at all roof truss/rafter joints at the upper sill plate for the same reason, and roof cover had to be hard tiles, often flat - tiles were also tied with wires to the sub-roof panels to prevent them from becoming projectiles. South Florida paid dearly for relaxing its construction codes, especially in the aftermath of Hurricane Andrew.
Yeah cmu would work on earth, but to get it to the moon, it would cost a million dollars to bring 1 cmu block over there. A 3d printer that uses the moon’s material is the key to our survival
@egcruzer I think the automation of the building process is the attraction. The labor costs for a concrete block home are higher than for a timber frame home. But a printed home costs far less than a timber frame home. The printed home does need humans to construct the roof, doors, windows, plumbing, electric, mechanical, and finishes. But actually building the walls is far less labor.
Hello Jarett! It's nice and resourceful that you have covered the industry of 3d printed structures on various parameters. I suggest you and officials from Cobod along with Mensa-Korte have a detailed video on the insurance, valuation and claims settlement of damages aspect of 3d structures.
Those are tough topics! I recently had a guest on from a printing company in Germany and we talked about how experimental construction in Germany isn't eligible for regular insurance! That episode will air on the podcast channel next week.
@@automateconstruction wow amazing!!! Youre so great Jarett, been following you for a couple years at least now and you are THE guy! My boyfriend has done a lot of commercial art and tech classes and has done 3d printing but not for houses; he turned me onto the 3d printing of houses. we have a plan to build in florida 3D as much as we can for a spanish mission style house with an enclosed courtyard!!!! Crazy huh???! oh we have a dream!!!
I saw one news report that the buyer of two of the four Icon homes in Austin could not get homeowner's insurance - in order to get a mortgage (obviously she paid cash). Never heard how it resolved, and have not since found that report.
Appreciate dispelling the myths here, especially costs. I’ve watched debunking shipping container homes as they’re pretty much a scam. 3D printing looks legit, just not cheaper, faster or better than stick built, other than having better R-value walls and walls being fire resistant.
Eventually, I will make a shipping container art studio, but it will likely be pretty rudimentary. Windows and a door with some electrical conduit for power will be the extent of the modifications. I was originally thinking of making a rental cottage with 3 containers, but no. Too expensive and too small an ROI.
The walls are hollow so if they leave access to the top in the attic, I don't think this would be a big issue. Easier than pored concrete or cinder-block construction I would imagine.
All high technology projects involve tradeoffs. 3D printed construction technology is still in its infancy so I readily expect improvements in techniques and processes, standardization, and cost reduction in the years ahead. I'd be interested to compare the carbon footprints of a 3D printed concrete house to comparable sized wood-frame and cinder block homes to see which is greener.
Thanks for this update on 3DCP. This is a fascinating technological development, and it is great to hear where it is at any given point in its development.
Please state specific dollar numbers of 3d printed houses compared to traditional timber frames houses of the same square foot / metre. Also does there need to be flat land all around for the printer to be set up on? What if the land is not flat and clear etc?
Are there any radon concerns with concrete walls all over. Typically it’s only for the foundation and potentially a basement where people don’t spend a lot of time in.
@MichaelWittner oh so gut everything out of your house to pressure wash the interior walls? Or power wash your bed, dressers, clothes and anything else you don't want wet everytime you need to clean your walls lol
same. even with a vacuum with a hose and brush, that would take hours to clean. that being said, the solidity of the structure should allow you to keep most dust out if you really want to. porches could be used as airlocks to help prevent dust getting in. a nice filtration system can keep the air clean. the look is nice. you could easily fill it in though, with mud of some kind, or put board over it.
Some people are going to want to show off the fact that the home is "3D" and what you have raised is an issue. However, the walls don't have to be left that way. First, they can be smoothed during construction on on one or both sides so that they will be a normal, flat and smooth wall. Second, you can still hang drywall or paneling if desired.
I imagine a decentralized approach utilizing a team of bots. One or two programmable types, articulators and haulers coordinated and redundant. A team of 10 or 20 would do almost all tasks: mixing, hauling, scaffold build and tear down, extruding, reinforcement positioning, error and quality control management, washing and cleanup, multiple extruders would allow for better intricacy without slowing things down. About the size of the Silent Running bots. .... and another thought, maybe there is a way to use recycled plastics in fiber form to strengthen the extrusion. ... Great work! btw.
3:00 is the key thing for me. We can certainly acknowledge that for initial trials, there will be hiccups. But when I think about how a house is built, is this method really save time in the entire process, especially when looking at any additional work required post-wall build.
Could the addition of crushed or shredded PET / single use plastics into the concrete help with durability? I live in tornado alley and look at these home types as possibly safer than the paper houses they slap together quickly. Impressive subject, and thank you for doing the work to bring this list together.
@@thirstypilgrim97 +1 for that suggestion - plus consider circular or dome shapes and naturally less susceptible to wind. Solid roof, not a wooden one and you should be pretty bomb proof. And heavy metal window shutters. You could even build earth banks to minimise the above ground profile - Hobbit home style. Always seems insane people just accept their house will be demolished in a tornado - just BUILD them tornado proof! 🤷♀
it is usually about the money and fashion. some people would not even like someone to paint their house purple, let alone make it round or other shapes, so fashion dictates they should look like other houses around them. then there is the money problem. houses are expensive, and contractors already know how to make a square home. even putting in a few nicer features can make the price too high and totally learning new construction techniques would make the price go through the roof, pun intended. many contractors will not even do solar panels. There are also space efficiency issues. the land is very expensive, and is generally also squarish, leading people to want squarish homes. for instance, think of all the floor space you lose if you cut off the corners of your house. overall, it is a lot easier to just agree to have a squarish house and hope you are not hit by a tornado. that being said, a squarish house made of concrete would be fine in a tornado, but then we are back to the expense problems. @@james.telfer
It's possible in the desktop ish sized printers. MatterHackers or one of the pro brands has a carbon fiber injection process. It puts a continuous stand into 3d printed tools
i also wonder if there could be a moving robot that can print, instead of a stationary printer. We have a lot of advancements in robotics. Maybe a sort of spider that can print the building and even build the other components in the near than you think future. Then you can connect a hose for the materials. But I imagine so much... What if there is a way to get the easiest fastest building possible, that would be cool. A project starting from nothing and making all materials from scratch and streaam line the whole process to be as fast as possible, just as like a project. From the plants needed for insolation etc, the pipes and electric managed as well, with maximal sustainability at each stage and the latest technology used.
I think once a standard is developed it’ll become more viable. For now I think where the technology shines is quickly building template houses in subdivisions to minimize travel and setup costs.
Seems to me that 3D Concrete home printing, is something that might be better done making Prefab Panels, with Insulation etc already applied, inside a Shop; rather than printed Onsite. While one large Cement Mixer can be used for several Cinder Block Home constructions, with 3D Printing; several homes being put up simutaneously, would require several Printers printing simultaneously !
i think the opposite. the strong suit of this construction is that you can make all of the walls a singular unit. it should be very strong. having more printers would not be a huge issue, if the construction were common. most small companies could just rent them.
Being from the northeast the cold windy weather makes me look at the key points like thermal break, I don't see a thermal brake at the window and door openings?
Wow! Jarett this very insightful for anyone without experience. It took me 2 years to understand those Myths. Stephan Mansour is the most helpful and realistic guy in the 3D concrete community. Stay great as you are Jarett. In fact, your videos helped me a lot!
maybe do a video on the different kinds of concrete building construction (if you haven't already). 3D printing vs monolithic domes vs preformed slabs etc and which would be the most beneficial in which climate environments.
Too many of these are just common sense understanding of the basics behind either construction or 3d printing in general. There were a few very good ones too which require some experience to understand. Im doing a desp dive on this topic and I'm glad to have found your channel. Keep it up.
What I took from this video is what I had assumed even before I knew anything about the process and materials and that is that if anything it is more complicated and maybe even more costly to use this method to build a house or small structure. But I still understand you have to start somewhere. I remember home computers and the Commodore 64 when it came out and the first mass produced cell phones and they were really expensive for what they actually did which was not a lot but now you can get something that's comparatively a supercomputer at Walmart for 300 bucks which is amazing
One thing that never really gets asked or answer is, "What is the point". Is it to be better than stick built? Cheaper, more durable, more stable? Even if it's not cheaper now, maybe it will be less expensive down the road but is there a true reason to do this versus what we have been doing other than it CAN be done?
to me, it is the strength of a solid build unit, and all of the amazing shapes you could make, including building structures inside of the walls. i think 3D printed buildings are the future. even the way some buildings are cast of concrete now is very similar, and i have seen builds where they raise the building area up with the building. build a floor, raise the equipment up, build another floor, etc.
I'm not clear on the advantage of modern 3DCP -- vs -- modern cinder-block construction for a typical 3br/2ba home. What makes it compellingly preferable?
Anything about Mighty Buildings? They use UV polymer something or other, prefab the modulures and than deliver it, avoiding a lot of the variables in constuction and they claim to be able to build extremely fast as a result and effectively no waste.
Hello Jarrett. You give courses; are you and architect? Who is the expert you are talking to here? What happens when and opening, is wrong size or in wrong place? How about walls that need to be relocated?
Hello Carrl. After many comments asking for one I made a course on how to 3d print a house. No I’m not an architect, the course does not give you the tools to be an architect. It only showcases the commonalities and diffidences between the many projects I’ve witnessed from the ground up. I’m talking to a leader of the ASTM committee on 3D printed construction. If an opening is too big they can cut it wet or dry. Mistakes happen in all kinds of construction and they compensate for it. If it’s too far off for spec it must be redone but that’s uncommon. Phew that was a lot of questions.
I bet it wouldn't be difficult to find a way to smooth the surface as it prints, like a tool head extension where perhaps a heated metal plate or something could smooth the layers
How does 3D printing deal with steel reinforcing? In my country in cyclone/hurricane areas, buildings are required to have steel rods tying the roofing structure to the foundations, so steel reinforcing cannot be avoided.. These clips of 3D printing don't seem to show steel reinforcing, and it seems to me that steel would make it difficult for the 3D printer to work around.
Most of the shortcomings listed in the video are due to the fact that the market for such construction is still in process. It is foolish to expect from a new product that all supplies, supply chains, and contractors will be at the same level as in the established monopoly market. 3D Homes is an innovative product and is marketed accordingly. Other things being equal, this is indeed a much more convenient, high-quality, and efficient type of construction than traditional frame houses (in the USA).
it might be, if you want to use wood which is light weight for transportation. i like these thick, dense, walls. heating and cooling costs should be lower, with concrete, and they should be resistant to damage.
Heating and cooling costs wont be lower with concrete walls. The cheapest you can go is probably a house made from SIP panels. They are also less expensive and a lot faster to build on side. I also wouldnt be so sure about durability of these walls vs the traditional brick wall. These walls could be very prone to fractures and cracks. The foundation wont always be perfectly still, it can sink a little on one side of the house over the years, with the brick house it can crack a little, but with a house the crack will probably go through the whole construction. @@itoibo4208
Only in light hyw size spec housing, 3d printing will beat market in customization longevity and price per sq foot after fully integrated assembly is automated. What there doing wrong is not contrling thermal managment Plug in play Spool in electronic plumbing and H vac assembly inagratin with sip pre fab roofing all installed off same inclosed gantry.
The value of printed concrete is to create a "tub" surrounding a house in a disaster prone area. Or the ground loor of a house in a disaster prone area. No penetrations allowed, such as doors or garages, though. The stairs could be enclosed, and watertight doors installed. Any upper construction anchored to the "tub" isn't going anywhere. Should be a way to have a levee around your house, without violating the "must accept the flood" ordinances that prohibit homeowner levees or prohibit manmade islands.
building walls is about -10 percent of the time when building a house, it is the cheapest thing, so about the uselessness of this technology,and not to mention that you won't replace people with that machine, it still requires an operator plus a qualified programmer technician and transport, and setting up and removing the machineso it turns out to be much more expensive
In regards to “price”….you still get WAY more house for the money than a conventional built house. It’s cheap enough to print so that the builder can afford to add in extras like steel roof, solar panels etc all for the same price as a conventional he built house. Not to mention the fact that this house has much greater secondary characteristics, like thermal, retaining, strength, longevity, etc. etc.
You guys are mentioning “myths” that are the same for conventionally built houses…and we’ve had hundreds of years to correct those items but can’t. There will definitely be a learning curve with any new process. Just like electric cars, just started becoming mainstream 10 years ago, and have passed-up gasoline vehicles that have been around for over 100 years. Printed houses will pass up conventional built homes. It will just take a little time to learn the best way.
apart from all the other issues with the technology I definitely don't like the part where they sell their own cartridges with special material and their machines work only with THEIR cartridges... if anyone remembers the whole ink printer cartridges controversy around HP then you know what I mean by that.
We need a showdown, two teams build the same exact building, one with 3d printing, one with traditional wood. Who will finish first? I think you can have wooden walls up in a day right?
"The media" have their own problems and their own agendas. They want an interesting story to get readers. That story could range from "3-D printed houses are amazingly cheap/fast" to "3-D printed houses are a lie". The reporters are not likely to have easy answers and, as the guy in the podcasts says, they are still working out the details and trying different things, plus the companies who make the houses want it to look promising for buyers, and the reporters are less likely to know the difference between exaggeration and the truth, and it takes time and money to do real research, where often the reporters need to write a story for very little pay. There are a lot of reasons why it is hard to write objective and accurate stories about 3-D houses, and to make them interesting as well.
For the issues of mix consistency and having to deal with different atmosphere conditions and weather based on location, why not make some kind of portable shield to put around the area you're printing so that you can create a controlled environment. This should reduce anomolies and help speed up dry times if you also make the shields have a drying feature. Food for thought...
The most straightforward method will be to do a small test mix after taking environmental conditions into consideration, see how it fares, tweak it here and there and one should be good to go. Even regular construction is affected by local climatic conditions hence why for example when using concrete it's good to look up regional guidelines to get the best results, too much humidity during construction can affect the curing properties and structural strength can be compromised.
Yes, a shield, protection against wind, rain, there happens to be 1, fast, easy assemble, take down, cheap, reusable, large coverage, transportable, not much weight, available materials, tarp between wire mesh or other, reinforced with rebar
It seems that 3D printing is more efficient and cost effective only when printing small prefab houses, or prefab modials that could be assemeled on site, but using the printer on site to print big houses just doesn't seem to have many advantages over other building styles.
That’s the milestone project I visited it in Eindhoven you can watch the tour on my RUclips channel. (Also it’s just in the video for nice visuals I’m not calling them out for the just add water thing, that wasn’t them.
@@marko8095 Yep, funny story about that day... I was visiting Vertico and their CEO was kind enough to drive me over to the milestone house even though it's a Weber Beamix project (they are friends). The door happened to be open and a realtor was there who was kind enough to show us around and let me film. Pretty lucky I was able to get the footage!
I actually stayed in the 3D printed home at the very beginning of your video, currently being used as an AirBnb in Austin. I also visited the Icon home development in nearby Georgetown. Interesting stuff. I'm not sure what the compelling selling point is beyond the novelty of it. The homes in Georgetown were priced around $500K so there was no advantage versus stick building. I think it needs some sort of clear and universal advantage to make any significant inroads in home construction. I also assume that 3D printing does not lend itself to one-off construction (except for luxury homes) given the set-up overhead of the equipment.
in places like Florida where I'm from, insurance companies will no longer be writing policies for homes w mortages due to paying out every year for hurricanes. I can see the benefit of them if insurance companies will write policies for concrete homes. Same for homes in tornado alley etc. Everyone in florida thats a homeowner in 30 years will be either rich people or uninsured which sounds like a nightmare. Not to mention stickframe newbuild in a moisture rich, termite rich state, sucks ass and they dont last longer than the life of the mortgage in the first place due to getting rained on all the fuckin time during construction. A whole subdivision was built behind my parents 15-20 years ago and pretty much every home has had major work done on them due to rot.
It's way, way early in the development arc of 3D printing of homes. While making a list of criticisms is fine and useful, calling them "lies" is a bit over the top. If the tech is really going to be viable, the issues will be worked out. If it's not going to work, it will fall by the wayside along with all the other futuristic "innovations" that have failed over the decades.
Like any other technology there is lot of "marketing fluff" about 3DP in all aspects of production.. for mass production or construction industry it will be lot of commercial/ legal issues, + purely niche usage .. lets hope lot of these companies don;t do the "Fake it until make it" mantra! like that Teranos by the way 3DP is great technology and it has been around fora while nothing new really once it come out of patent protection it become widely known
ASTM have nothing to how a house is built. It ONLY has to do with testing of materials. ICBO is the standard many state and localities are or have adopted.
@@automateconstruction ASTM is American Society for Testing and Materials. That's how you go about certifying if a material meets a certain standard. Like R rating for insulation or break strength for concrete. Absorption rates for CMU's or density of asphaltic concrete. ICBO is International Conference of Building Officials. These are the standards that will tell you if the stairs are up to "code". The two are completely different areas of the construction industry. ASTM also covers many things that are not even in the construction industry because they cover testing not codes. Been in construction industry for over 20 years and am certified in quite a few ASTM procedures.
@@automateconstruction 1 Scope This document defines quality assurance requirements for Additive Construction (AC) concerning building and construction projects in which additive manufacturing techniques are used for construction. The requirements are independent of the material/materials and process category used. QC for additive manufacturing, not a code for the design of the building. They do work hand in hand but one is not the other.
as I was listening, nearly every point was equally applicable to all kinds of constructions and not really industry specific. Prime example, construction waste. So not much really new, as for the overall process it seems.
When you start innovating and thinking outside the box you are part of the solution not the problem. 3 D printing should be and is a better way to build ... why? Because measure twice cut once is now measure cut, as well as its only as good as its programmer, training and expertise take the place of all the mistakes made by measuring. Measuring is never the same from one area to the next but here it is. Its truly wonderful. Don't let these critics stop you.
Both of us in the video are dedicating our careers to this tech. Our criticism comes from an optimistic place and I do run with time some of these claims which are inaccurate today will become true.
they need to adapt a smoothing tool to the printer to get rid of the layered look. how do you clean walls like that ? say in a washroom? the only way to paint it is with sprayand that will take a lot of paint to get into all the grooves.
Every 3D printed home video I watch is pushing the assumed narrative that these companies will help homelessness. There are folks that can’t afford these homes that work long hours in this country (USA). I get that it’s a great insert on a business plan/grant proposal for government funding and corporate investment but it’s a lie (at least in this country)..If you’d please, stop using this line about homelessness. This may be the new building normal but I don’t understand why homeless ppl who won’t or can’t work are being offered free housing at the expense of those who also can’t afford housing but care to work and pay outrageous taxes. I can’t believe I have to say this but the housing crisis is being caused by investors and so called “helpful” government funding. Wake up!
It's the constructors who rip off are being cut off with this. My home was built by a substandard contractor who delayed the project, demanded more, and the walls collapsed. At least 3D printer works faster and less people are involved.
@@automateconstruction thanks. GuyExpo in Guyana invited a US company and a house was built. I hope this becomes common in Guyana as we desperately need honest construction workers. Guyanese invest a lot in building houses and it is a field of business. You should pop there someday.
Re cost- If shipping and assembly of the equipment is a very large component of cost, would constructing 100 houses in the same area and thus sharing those costs out by a lot* make DCP cheaper? *We're assuming people are prepared to 'wait their turn', while the houses are constructed, rather than 100 machines arriving. (But, Hey! It's only 24 hours a house, if I heard you right.)
Because of course you can grow new rock. 🙄 Maybe it's my multigenerational background in managed forestry, but it's always laughable when I see/hear these kinds of comments. People prefering plastics and other non-renewable resources over a crop that is regrown continually because they want to "save trees" shows they don't really care about environmental concerns and don't plan to be around long enough to witness the ruination of the only inhabitable planet we have. Or maybe their experience with trees is limited to a copse in their local park. I always wonder what they eat if they're so hell-bent on saving renewable vegetation over non-renewable materials-Quarry cereal, maybe. "But you can recycle plastic!" Is that what you were going to say? Do you have any idea how that's done, how efficient it is, what chemicals are involved, and what the quality actually is of 100% recycled petroleum products? There's a reason you don't see "100% recycled material" on most petroleum-based recycled products. Not to mention how quickly and into what components it breaks down into the surrounding ground water and soil (much more quickly than you think; that "1000 years" thing is bullshit and that's not a good thing), especially with UV exposure. Paper, on the other hand, is manufactured with fewer and less volatile chemical compounds, can actually be recycled (again with fewer chemicals), and wood can be reused, repurposed, and recycled without the vulnerabilities of plastics. As a building material, it's actually quite flexible. Adding an outlet or a moving a staircase is relatively easy. As for "3D printed" homes, it's merely extruded concrete (not really new, my dad was doing this in the 1940s while working with the US Army Corps of Engineers), not really a new miracle product, just new(ish) packaging, delivery, and trendy label. Concrete is an excellent building material, but as someone else pointed out elsewhere in these comments, it's hard to regulate quality, moisture, etc, on-site (not to mention site access limitations and the costs of setting up and maintaining the delivery system). They made a good case for more affordable, flexible, and quality controllable prefabricated materials already available and in use. Transportation costs are going to be similar as well, since a similar amount of any building material would have to be brought to the site, and in the case of "3D printing" you're also moving the massive apparatus both to and from the site. Maybe someday, but this just isn't ready for prime time or budget housing. Aesthetically, it's interesting and looks nice. Right now, that's the best argument for it, if buyers prefer this aesthetic over others.
"3D printing" carries tons of terrible conceptional baggage. The phrase should be "digital placement", it does not matter at all whether it's placed by a nozzle or not. Dimensionality reduction is not the way forward.
It depends what you mean by print the house if you want to print it on site in concrete, Emergent is the only girl by November in California doing that with houses right now. They have some projects in northern California. I also know of a couple groups in LA that have concrete printers, RIC may be starting building projects soon and rumor has it Winsun will be starting construction projects in LA as well.
How is it cheaper than regular CMU blocks ?? Just the labor costs?? Surely it's using more grout/concrete than the standard wall thickness of CMUs --- Its like NFTs - i just don't understand where the "savings" comes in - the block "masons" are just a small fraction of the price of the home
There are many different types of 3d printer construction robots and designs. It's still cheaper faster and more efficient than regular homes. Especially in a society where most people are poor. This and many other technologies, will make our world far better.
@@automateconstruction for what's involved, it should be far cheaper. If the government wants to screw people like they have many times, then yeah, they'll make 3d printed residences more expensive. They don't want better and cheaper tech out there. It goes against their greed fake power and control issues.
@@automateconstruction as it explains in the video and others, it depends on what material your using. Each 3d printed homes price, would be subjective. It depends on what is used to make it.
Today's materials are tomorrow's problems, everyone who has worked in construction is aware of that saying, I see many issues with these but an obvious one is expansion joints, All concrete needs an expansion joint, floor slabs, even roads, but a south facing wall with expand and contract a lot, thin walls must be prone to cracking, moss on north facing walls in the northern hemisphere will be horrendous with that amount of texture, compression failure after a certain height and weight has been reached,. I'm all for new techniques but they need to be cheaper than this and compete with conventional buildings, brick walls, tiled roofs, wooden joists, its taken years of trial and error to get to the best method of building,
It has always seemed like 3d printed houses address creating the shell of the house, where the bulk of the cost is in labor and materials is in the plumbing, heating, and electrical systems. In any case, reducing the cost of construction is irrelevant to housing pricing for consumers. It just alters the amount that is split up between municipalities, speculators, and contractors. You can't have cheap housing or that will destroy the property values of existing owners. As long as zoning laws, land use regulations, licensing requirements, and other such restrict the supply of housing, and central banks manipulate interest rates to keep a guaranteed amount of housing inflation, rent will be high, and overall a lot of the economy will be directed towards housing.
Hasn't this technology matured yet to the point where they can eliminate that annoying horizontal ribbing from the printer layering? All I can see is crevice upon crevice for dust to collect on both inside and outside wall surfaces. It's still at the novelty phase.
Eventually yea by using a mold in the place so it dries straight. And I am sure eventually they will add the quicklime Roman ingredient that preserved concrete by allowing it to self heal cracks
OK, guys. I am sure most people don't expect their 3D printed home to be $10,000. Builders have an idea how much it cost to build a 3D printed home do they not? Just give the buyer an estimate cost per square feet. Everybody know it is still a new technology and price will change over time. Why make it sound so dramatic?
It is the future. Especially here in Europe where stick houses never became popular. Majority of housing is built from prefabs, cinder blocks or bricks.
As with all technologies, healthy skepticism is needed.
Pumicecrete is by far the best building material on the planet Pumicecrete is a mixture of pumice cement and water mixed and poured into a set of reusable forms walls are poured from 12"to 24" thick pumicecrete is fireproof termite proof rust rot and mold proof and has a high R value and good sound attenuation solid poured walls means no critters can live in your walls Pumicecrete can be built for a fraction of the cost and time and is perfect for automation

Got Real!! 12. Thermal Bridging. 13. Moisture Control It can all get better by designing machines to make exactly what wall/building assemblies should be, rather than tweaking wall/building design to match what existing 3D printers already do. Imagination required!
It strikes me that the real future of 3D printed houses is somewhere in the middle-whereby the houses are not prnted on site, but in a factory-much in the manner of how typical pre-fabricated timber houses are built-in purpose-built factories, but in (the fewest-possible number of) easily assembled *segments* that are trucked to site and craned-in.
(Thoughts?)
@@danohanlon8316 This brings up all the issues of precast concrete, that are very significant cost problems, especially for residential. More challenges for structural, utilities, precision, fit and finish, a need for heavy equipment, higher insurance costs...
@@SpaceCrete I hear you. But I’m really hinting at a marriage of both concepts, whereby the notion of digitally PRE-printed concrete *modules* display at least the potential to eliminate many of the problems of reinforced concrete, such as formwork. Can’t prove it; I just see it. (Maybe!)
@@danohanlon8316 We don't need formwork. We can use concrete to glue everything else together by doing it last.
I know this is in it's infancy stage and later on issues can be addressed.
That said, you'd have to take into account the environment, climate, weather, fault zones, flooding zones and so on.
So, building these homes in tornado alley would have to be different from one built in an environment of heavy snowfall.
It will be interesting to see how this progresses.
Truly respect your willingness to highlight these man. You are only strengthening the space by doing so. Well done 👊🏻
Repairability. In a metal framed structure or wood framed home any damaged components can be repaired or replaced fairly easily without lasting damage, but every cut into concrete permanently reduces it's strength.
Locality, you touched on the "just add water" bit, but it goes even beyond that. The availability of cement ready aggregates are not universal... the potential cost of transporting tons of minerals will add up very quickly. Also, cement walls may be great for a temperate and dry location, but places which are extra cold or wet.... not so much.

Thank you for this. I am a consumer and highly motivated to build a 3D printed home in the Pacific North West of the US for myself.
I am in the very early stages of this, just working on the idea of it. It is really difficult for consumers to get any usable info, such as pricing, or where to start. I realize a lot of this is similar to building any home, lot prep, hiring an architect, locating a contractor. The newness of 3D printing adds a wrinkle. Will banks write a construction loan for such a project? Are there 3D printer contractors within Washington State? How to find the architect who can think outside the box, but without spending a fortune.
My project will be quite modest, a single level 1,200 to 1,400 square foot home with one bathroom, one bedroom, one closet, and the rest will be open plan. So your busting some of these myths is helping a lot.
I calculate it will take me 12 to 18 months to get this done from start to finish. I will keep you posted on my progress and share any insights that might help others.
BTW, I do have a background in construction and in real estate but I am trying to retire so not able to do much of the work myself.
These homes will be most valuable as “ neighborhood “ projects as opposed to single home construction. Hopefully the larger scale of neighborhood/ subdivision projects can eventually underwrite transportation costs for single or smaller projects.
Maybe even low income housing?
I’m for advancing the development of 3D printed homes but at the same time I never understood why they don’t use CMU block to build homes. Not only is it a very well understood construction method but the blocks are made in a controlled environment ensuring quality control of not only the mix but also consistent density of the finished product. CMU also has a consistent flat surface allowing other materials like insulation board, hardy board or other finishes can more easily be applied. As someone with a FDM printer at home I’d be worried about layer adhesion, consistent density and repair methods of poor quality sections.
Unless you are talking about something different, here in South Florida, most homes appear to be built of concrete block. My house, built in 1959, is concrete block so it's been around for a long time. There are a lot of commercial projects going on that use tilt wall construction. To me, that makes more sense than printing.
@@rogermccaslin5963 Older South Florida building codes required that exterior walls be made of 8 inch CMU's for hurricane tolerance. They also required tie straps at all roof truss/rafter joints at the upper sill plate for the same reason, and roof cover had to be hard tiles, often flat - tiles were also tied with wires to the sub-roof panels to prevent them from becoming projectiles. South Florida paid dearly for relaxing its construction codes, especially in the aftermath of Hurricane Andrew.
Yeah cmu would work on earth, but to get it to the moon, it would cost a million dollars to bring 1 cmu block over there. A 3d printer that uses the moon’s material is the key to our survival
@egcruzer I think the automation of the building process is the attraction. The labor costs for a concrete block home are higher than for a timber frame home. But a printed home costs far less than a timber frame home. The printed home does need humans to construct the roof, doors, windows, plumbing, electric, mechanical, and finishes. But actually building the walls is far less labor.
Hello Jarett! It's nice and resourceful that you have covered the industry of 3d printed structures on various parameters. I suggest you and officials from Cobod along with Mensa-Korte have a detailed video on the insurance, valuation and claims settlement of damages aspect of 3d structures.
Those are tough topics! I recently had a guest on from a printing company in Germany and we talked about how experimental construction in Germany isn't eligible for regular insurance! That episode will air on the podcast channel next week.
@@automateconstruction wow amazing!!! Youre so great Jarett, been following you for a couple years at least now and you are THE guy! My boyfriend has done a lot of commercial art and tech classes and has done 3d printing but not for houses; he turned me onto the 3d printing of houses. we have a plan to build in florida 3D as much as we can for a spanish mission style house with an enclosed courtyard!!!! Crazy huh???! oh we have a dream!!!
@@elizabethbennet4791 That's awesome thank you so much for you kind words can't wait for an update on your project in the future!
I saw one news report that the buyer of two of the four Icon homes in Austin could not get homeowner's insurance - in order to get a mortgage (obviously she paid cash). Never heard how it resolved, and have not since found that report.
@@SpaceCrete I met her when I stayed there, she joined Belinda Carr and I for a slice of pizza. Good people! I hope they got their insurance sorted.
Appreciate dispelling the myths here, especially costs. I’ve watched debunking shipping container homes as they’re pretty much a scam. 3D printing looks legit, just not cheaper, faster or better than stick built, other than having better R-value walls and walls being fire resistant.
i live in a container house....when i go on vacation i just put it on a container ship,i been to 198 countries so far!
Eventually, I will make a shipping container art studio, but it will likely be pretty rudimentary. Windows and a door with some electrical conduit for power will be the extent of the modifications. I was originally thinking of making a rental cottage with 3 containers, but no. Too expensive and too small an ROI.
What about the challenge of installing electrical/plumbing systems? And I'd hate to have to renovate one of these someday.
It's simple to leave conduits and e-boxes. Not challenge at all.
@@phil562you have no experience in renovation if you think that.
The walls are hollow so if they leave access to the top in the attic, I don't think this would be a big issue. Easier than pored concrete or cinder-block construction I would imagine.
All high technology projects involve tradeoffs. 3D printed construction technology is still in its infancy so I readily expect improvements in techniques and processes, standardization, and cost reduction in the years ahead. I'd be interested to compare the carbon footprints of a 3D printed concrete house to comparable sized wood-frame and cinder block homes to see which is greener.
Thanks for this update on 3DCP. This is a fascinating technological development, and it is great to hear where it is at any given point in its development.
I saw thw Lennar cummunities of 100 houses, priced at around 500k , so "the biggest lie: 3d house printing does not resolve the housing crisis,
Please state specific dollar numbers of 3d printed houses compared to traditional timber frames houses of the same square foot / metre. Also does there need to be flat land all around for the printer to be set up on? What if the land is not flat and clear etc?
Construction isn’t commoditized like that, costs in one region could be double another
Are there any radon concerns with concrete walls all over. Typically it’s only for the foundation and potentially a basement where people don’t spend a lot of time in.
Seems like they would be a nightmare to clean all the interior walls.
Not at all. We got pressure. Washers lol😅
@MichaelWittner oh so gut everything out of your house to pressure wash the interior walls? Or power wash your bed, dressers, clothes and anything else you don't want wet everytime you need to clean your walls lol
same. even with a vacuum with a hose and brush, that would take hours to clean. that being said, the solidity of the structure should allow you to keep most dust out if you really want to. porches could be used as airlocks to help prevent dust getting in. a nice filtration system can keep the air clean. the look is nice. you could easily fill it in though, with mud of some kind, or put board over it.
Some people are going to want to show off the fact that the home is "3D" and what you have raised is an issue. However, the walls don't have to be left that way. First, they can be smoothed during construction on on one or both sides so that they will be a normal, flat and smooth wall. Second, you can still hang drywall or paneling if desired.
You could plaster the walls fairly easily and make a smooth finish which would make sense to prevent dust and germ buildup.
I imagine a decentralized approach utilizing a team of bots. One or two programmable types, articulators and haulers coordinated and redundant. A team of 10 or 20 would do almost all tasks: mixing, hauling, scaffold build and tear down, extruding, reinforcement positioning, error and quality control management, washing and cleanup, multiple extruders would allow for better intricacy without slowing things down. About the size of the Silent Running bots. .... and another thought, maybe there is a way to use recycled plastics in fiber form to strengthen the extrusion. ... Great work! btw.
Love it! Thanks!
3:00 is the key thing for me. We can certainly acknowledge that for initial trials, there will be hiccups.
But when I think about how a house is built, is this method really save time in the entire process, especially when looking at any additional work required post-wall build.
Would be also a good idea expose the ugly truth about 4x2 stick construction.
Is anyone actually deluded about stick construction? I think it's only accepted by Americans because it has become the norm
Could the addition of crushed or shredded PET / single use plastics into the concrete help with durability? I live in tornado alley and look at these home types as possibly safer than the paper houses they slap together quickly. Impressive subject, and thank you for doing the work to bring this list together.
Have you considered Perfect Block Composite ICCF? It's rated for 250mph winds.
@@thirstypilgrim97 +1 for that suggestion - plus consider circular or dome shapes and naturally less susceptible to wind. Solid roof, not a wooden one and you should be pretty bomb proof. And heavy metal window shutters. You could even build earth banks to minimise the above ground profile - Hobbit home style.
Always seems insane people just accept their house will be demolished in a tornado - just BUILD them tornado proof! 🤷♀
it is usually about the money and fashion. some people would not even like someone to paint their house purple, let alone make it round or other shapes, so fashion dictates they should look like other houses around them. then there is the money problem. houses are expensive, and contractors already know how to make a square home. even putting in a few nicer features can make the price too high and totally learning new construction techniques would make the price go through the roof, pun intended. many contractors will not even do solar panels. There are also space efficiency issues. the land is very expensive, and is generally also squarish, leading people to want squarish homes. for instance, think of all the floor space you lose if you cut off the corners of your house. overall, it is a lot easier to just agree to have a squarish house and hope you are not hit by a tornado. that being said, a squarish house made of concrete would be fine in a tornado, but then we are back to the expense problems. @@james.telfer
It's possible in the desktop ish sized printers. MatterHackers or one of the pro brands has a carbon fiber injection process. It puts a continuous stand into 3d printed tools
Guam, not 3D back when, but concrete withstands better in storms.
i also wonder if there could be a moving robot that can print, instead of a stationary printer. We have a lot of advancements in robotics. Maybe a sort of spider that can print the building and even build the other components in the near than you think future. Then you can connect a hose for the materials. But I imagine so much... What if there is a way to get the easiest fastest building possible, that would be cool. A project starting from nothing and making all materials from scratch and streaam line the whole process to be as fast as possible, just as like a project. From the plants needed for insolation etc, the pipes and electric managed as well, with maximal sustainability at each stage and the latest technology used.
How do they hold up in an earthquake? Varying magnitudes, durations, of course.
I think once a standard is developed it’ll become more viable. For now I think where the technology shines is quickly building template houses in subdivisions to minimize travel and setup costs.
As a temples I guess yes .. but then again if a company is going to use it as a selling point then they will' have to use it through the projects
Seems to me that 3D Concrete home printing, is something that might be better done making Prefab Panels, with Insulation etc already applied, inside a Shop; rather than printed Onsite.
While one large Cement Mixer can be used for several Cinder Block Home constructions, with 3D Printing; several homes being put up simutaneously, would require several Printers printing simultaneously !
i think the opposite. the strong suit of this construction is that you can make all of the walls a singular unit. it should be very strong. having more printers would not be a huge issue, if the construction were common. most small companies could just rent them.
Being from the northeast the cold windy weather makes me look at the key points like thermal break, I don't see a thermal brake at the window and door openings?
Wow! Jarett this very insightful for anyone without experience. It took me 2 years to understand those Myths. Stephan Mansour is the most helpful and realistic guy in the 3D concrete community. Stay great as you are Jarett. In fact, your videos helped me a lot!
maybe do a video on the different kinds of concrete building construction (if you haven't already). 3D printing vs monolithic domes vs preformed slabs etc and which would be the most beneficial in which climate environments.
Has Someone Designed An Optimizations Software To Help Calculate And/Or Automate The Best Mixture And Consistency Of The Materials In Real Time?
They’re just recently getting around to having the right sensors to do that

Too many of these are just common sense understanding of the basics behind either construction or 3d printing in general. There were a few very good ones too which require some experience to understand. Im doing a desp dive on this topic and I'm glad to have found your channel. Keep it up.
What I took from this video is what I had assumed even before I knew anything about the process and materials and that is that if anything it is more complicated and maybe even more costly to use this method to build a house or small structure. But I still understand you have to start somewhere. I remember home computers and the Commodore 64 when it came out and the first mass produced cell phones and they were really expensive for what they actually did which was not a lot but now you can get something that's comparatively a supercomputer at Walmart for 300 bucks which is amazing
One thing that never really gets asked or answer is, "What is the point". Is it to be better than stick built? Cheaper, more durable, more stable? Even if it's not cheaper now, maybe it will be less expensive down the road but is there a true reason to do this versus what we have been doing other than it CAN be done?
to me, it is the strength of a solid build unit, and all of the amazing shapes you could make, including building structures inside of the walls. i think 3D printed buildings are the future. even the way some buildings are cast of concrete now is very similar, and i have seen builds where they raise the building area up with the building. build a floor, raise the equipment up, build another floor, etc.
Click bait "Lies!!" . It's just sales for his own program

Thankfully a lot of these myths sound like issues related to scaling up a new technology, not a permanent issue
I'm not clear on the advantage of modern 3DCP -- vs -- modern cinder-block construction for a typical 3br/2ba home. What makes it compellingly preferable?
I would say the main advantages are freedom of design, cheap and accurate physical models, plus somewhat reduced physical labor on site.
Hello there, please do you have any idea how one can buy the 3D printer machine?
The houses at the 9:23 mark are only 3-D printed on the first floor, not the second floor. If it's so good, why did they only do the first floor?
Anything about Mighty Buildings? They use UV polymer something or other, prefab the modulures and than deliver it, avoiding a lot of the variables in constuction and they claim to be able to build extremely fast as a result and effectively no waste.
Hello Jarrett. You give courses; are you and architect? Who is the expert you are talking to here? What happens when and opening, is wrong size or in wrong place? How about walls that need to be relocated?
Hello Carrl. After many comments asking for one I made a course on how to 3d print a house. No I’m not an architect, the course does not give you the tools to be an architect. It only showcases the commonalities and diffidences between the many projects I’ve witnessed from the ground up. I’m talking to a leader of the ASTM committee on 3D printed construction. If an opening is too big they can cut it wet or dry. Mistakes happen in all kinds of construction and they compensate for it. If it’s too far off for spec it must be redone but that’s uncommon. Phew that was a lot of questions.
I bet it wouldn't be difficult to find a way to smooth the surface as it prints, like a tool head extension where perhaps a heated metal plate or something could smooth the layers
How does 3D printing deal with steel reinforcing? In my country in cyclone/hurricane areas, buildings are required to have steel rods tying the roofing structure to the foundations, so steel reinforcing cannot be avoided.. These clips of 3D printing don't seem to show steel reinforcing, and it seems to me that steel would make it difficult for the 3D printer to work around.
Most of the shortcomings listed in the video are due to the fact that the market for such construction is still in process. It is foolish to expect from a new product that all supplies, supply chains, and contractors will be at the same level as in the established monopoly market.
3D Homes is an innovative product and is marketed accordingly.
Other things being equal, this is indeed a much more convenient, high-quality, and efficient type of construction than traditional frame houses (in the USA).
👉💯👈👏
I was really wondering about this! Thanks for the program, thanks for the work.
Isn't it cheaper to have a factory-built house delivered and assembled on site?
it might be, if you want to use wood which is light weight for transportation. i like these thick, dense, walls. heating and cooling costs should be lower, with concrete, and they should be resistant to damage.
Heating and cooling costs wont be lower with concrete walls. The cheapest you can go is probably a house made from SIP panels. They are also less expensive and a lot faster to build on side. I also wouldnt be so sure about durability of these walls vs the traditional brick wall. These walls could be very prone to fractures and cracks. The foundation wont always be perfectly still, it can sink a little on one side of the house over the years, with the brick house it can crack a little, but with a house the crack will probably go through the whole construction. @@itoibo4208
Only in light hyw size spec housing,
3d printing will beat market in customization longevity and price per sq foot after fully integrated assembly is automated. What there doing wrong is not contrling thermal managment

The value of printed concrete is to create a "tub" surrounding a house in a disaster prone area. Or the ground loor of a house in a disaster prone area. No penetrations allowed, such as doors or garages, though. The stairs could be enclosed, and watertight doors installed. Any upper construction anchored to the "tub" isn't going anywhere. Should be a way to have a levee around your house, without violating the "must accept the flood" ordinances that prohibit homeowner levees or prohibit manmade islands.
building walls is about -10 percent of the time when building a house, it is the cheapest thing, so about the uselessness of this technology,and not to mention that you won't replace people with that machine, it still requires an operator plus a qualified programmer technician and transport, and setting up and removing the machineso it turns out to be much more expensive
100% 💪
In the videos I'm only seeing ground floor 3dprinted but not the first floor. Please explain.
In regards to “price”….you still get WAY more house for the money than a conventional built house.
It’s cheap enough to print so that the builder can afford to add in extras like steel roof, solar panels etc all for the same price as a conventional he built house.
Not to mention the fact that this house has much greater secondary characteristics, like thermal, retaining, strength, longevity, etc. etc.
You guys are mentioning “myths” that are the same for conventionally built houses…and we’ve had hundreds of years to correct those items but can’t.
There will definitely be a learning curve with any new process. Just like electric cars, just started becoming mainstream 10 years ago, and have passed-up gasoline vehicles that have been around for over 100 years.
Printed houses will pass up conventional built homes. It will just take a little time to learn the best way.
You're delusional.
Jarret Thank you. You just answered all . What about other materials than concrete, like the mighty buildings have
apart from all the other issues with the technology I definitely don't like the part where they sell their own cartridges with special material and their machines work only with THEIR cartridges...
if anyone remembers the whole ink printer cartridges controversy around HP then you know what I mean by that.
We need a showdown, two teams build the same exact building, one with 3d printing, one with traditional wood. Who will finish first? I think you can have wooden walls up in a day right?

Thank you!
"The media" have their own problems and their own agendas. They want an interesting story to get readers. That story could range from "3-D printed houses are amazingly cheap/fast" to "3-D printed houses are a lie". The reporters are not likely to have easy answers and, as the guy in the podcasts says, they are still working out the details and trying different things, plus the companies who make the houses want it to look promising for buyers, and the reporters are less likely to know the difference between exaggeration and the truth, and it takes time and money to do real research, where often the reporters need to write a story for very little pay. There are a lot of reasons why it is hard to write objective and accurate stories about 3-D houses, and to make them interesting as well.
How would they run wiring ducting and plumbing through walls in this?
Jesus its so hard to find peer review and critique from the huge mass of marketing and promotions that have been vomited out.
For the issues of mix consistency and having to deal with different atmosphere conditions and weather based on location, why not make some kind of portable shield to put around the area you're printing so that you can create a controlled environment. This should reduce anomolies and help speed up dry times if you also make the shields have a drying feature. Food for thought...
😂
More problems than benefits with this solution
@@francescocerioni8939 isn't that what real 3-d printers have, a box surrounding them?
The most straightforward method will be to do a small test mix after taking environmental conditions into consideration, see how it fares, tweak it here and there and one should be good to go. Even regular construction is affected by local climatic conditions hence why for example when using concrete it's good to look up regional guidelines to get the best results, too much humidity during construction can affect the curing properties and structural strength can be compromised.
Yes, a shield, protection against wind, rain, there happens to be 1, fast, easy assemble, take down, cheap, reusable, large coverage, transportable, not much weight, available materials, tarp between wire mesh or other, reinforced with rebar
It seems that 3D printing is more efficient and cost effective only when printing small prefab houses, or prefab modials that could be assemeled on site, but using the printer on site to print big houses just doesn't seem to have many advantages over other building styles.
They are not very cost effective, regardless of size

I actually stayed in the 3D printed home at the very beginning of your video, currently being used as an AirBnb in Austin. I also visited the Icon home development in nearby Georgetown. Interesting stuff. I'm not sure what the compelling selling point is beyond the novelty of it. The homes in Georgetown were priced around $500K so there was no advantage versus stick building. I think it needs some sort of clear and universal advantage to make any significant inroads in home construction. I also assume that 3D printing does not lend itself to one-off construction (except for luxury homes) given the set-up overhead of the equipment.
in places like Florida where I'm from, insurance companies will no longer be writing policies for homes w mortages due to paying out every year for hurricanes. I can see the benefit of them if insurance companies will write policies for concrete homes. Same for homes in tornado alley etc. Everyone in florida thats a homeowner in 30 years will be either rich people or uninsured which sounds like a nightmare. Not to mention stickframe newbuild in a moisture rich, termite rich state, sucks ass and they dont last longer than the life of the mortgage in the first place due to getting rained on all the fuckin time during construction. A whole subdivision was built behind my parents 15-20 years ago and pretty much every home has had major work done on them due to rot.
It's way, way early in the development arc of 3D printing of homes. While making a list of criticisms is fine and useful, calling them "lies" is a bit over the top. If the tech is really going to be viable, the issues will be worked out. If it's not going to work, it will fall by the wayside along with all the other futuristic "innovations" that have failed over the decades.
Like any other technology there is lot of "marketing fluff" about 3DP in all aspects of production.. for mass production or construction industry it will be lot of commercial/ legal issues, + purely niche usage .. lets hope lot of these companies don;t do the "Fake it until make it" mantra! like that Teranos by the way 3DP is great technology and it has been around fora while nothing new really once it come out of patent protection it become widely known
nice post, i as well believe that if the printers can be configured to sooth different locations at different conditions then progress can be made

ASTM have nothing to how a house is built. It ONLY has to do with testing of materials. ICBO is the standard many state and localities are or have adopted.
Municipalities may reference or adopt any standards they like. Just the existence of any standards at all is a step in the right direction.
@@automateconstruction ASTM is American Society for Testing and Materials. That's how you go about certifying if a material meets a certain standard. Like R rating for insulation or break strength for concrete. Absorption rates for CMU's or density of asphaltic concrete. ICBO is International Conference of Building Officials. These are the standards that will tell you if the stairs are up to "code". The two are completely different areas of the construction industry. ASTM also covers many things that are not even in the construction industry because they cover testing not codes. Been in construction industry for over 20 years and am certified in quite a few ASTM procedures.
@@repalmore Look at ASTM 52939
@@automateconstruction 1 Scope
This document defines quality assurance requirements for Additive Construction (AC) concerning building and construction projects in which additive manufacturing techniques are used for construction. The requirements are independent of the material/materials and process category used.
QC for additive manufacturing, not a code for the design of the building. They do work hand in hand but one is not the other.
as I was listening, nearly every point was equally applicable to all kinds of constructions and not really industry specific. Prime example, construction waste. So not much really new, as for the overall process it seems.
When you start innovating and thinking outside the box you are part of the solution not the problem. 3 D printing should be and is a better way to build ... why? Because measure twice cut once is now measure cut, as well as its only as good as its programmer, training and expertise take the place of all the mistakes made by measuring. Measuring is never the same from one area to the next but here it is. Its truly wonderful. Don't let these critics stop you.
Both of us in the video are dedicating our careers to this tech. Our criticism comes from an optimistic place and I do run with time some of these claims which are inaccurate today will become true.
they need to adapt a smoothing tool to the printer to get rid of the layered look. how do you clean walls like that ? say in a washroom? the only way to paint it is with sprayand that will take a lot of paint to get into all the grooves.
You can apply a smooth render.
Every 3D printed home video I watch is pushing the assumed narrative that these companies will help homelessness. There are folks that can’t afford these homes that work long hours in this country (USA). I get that it’s a great insert on a business plan/grant proposal for government funding and corporate investment but it’s a lie (at least in this country)..If you’d please, stop using this line about homelessness. This may be the new building normal but I don’t understand why homeless ppl who won’t or can’t work are being offered free housing at the expense of those who also can’t afford housing but care to work and pay outrageous taxes. I can’t believe I have to say this but the housing crisis is being caused by investors and so called “helpful” government funding. Wake up!
With all those curtains in your room, how is your room not sound treated? Still getting lots of reverb
It's the constructors who rip off are being cut off with this. My home was built by a substandard contractor who delayed the project, demanded more, and the walls collapsed. At least 3D printer works faster and less people are involved.
Sorry to hear about your bad experience. When this tech is mature it will solve those issues hopefully!
@@automateconstruction thanks. GuyExpo in Guyana invited a US company and a house was built. I hope this becomes common in Guyana as we desperately need honest construction workers. Guyanese invest a lot in building houses and it is a field of business. You should pop there someday.
Honesty is not something that can be printed. Consumers, business, and government have to be constant, consistent and always accountable.
Re cost- If shipping and assembly of the equipment is a very large component of cost, would constructing 100 houses in the same area and thus sharing those costs out by a lot* make DCP cheaper?
*We're assuming people are prepared to 'wait their turn', while the houses are constructed, rather than 100 machines arriving. (But, Hey! It's only 24 hours a house, if I heard you right.)
I don't see a thermal break.
What is the actual print material? Is it actually concrete or something else?
Wow! Imagine how many trees could be saved!
Because of course you can grow new rock. 🙄 Maybe it's my multigenerational background in managed forestry, but it's always laughable when I see/hear these kinds of comments. People prefering plastics and other non-renewable resources over a crop that is regrown continually because they want to "save trees" shows they don't really care about environmental concerns and don't plan to be around long enough to witness the ruination of the only inhabitable planet we have. Or maybe their experience with trees is limited to a copse in their local park. I always wonder what they eat if they're so hell-bent on saving renewable vegetation over non-renewable materials-Quarry cereal, maybe.
"But you can recycle plastic!" Is that what you were going to say? Do you have any idea how that's done, how efficient it is, what chemicals are involved, and what the quality actually is of 100% recycled petroleum products? There's a reason you don't see "100% recycled material" on most petroleum-based recycled products. Not to mention how quickly and into what components it breaks down into the surrounding ground water and soil (much more quickly than you think; that "1000 years" thing is bullshit and that's not a good thing), especially with UV exposure.
Paper, on the other hand, is manufactured with fewer and less volatile chemical compounds, can actually be recycled (again with fewer chemicals), and wood can be reused, repurposed, and recycled without the vulnerabilities of plastics. As a building material, it's actually quite flexible. Adding an outlet or a moving a staircase is relatively easy.
As for "3D printed" homes, it's merely extruded concrete (not really new, my dad was doing this in the 1940s while working with the US Army Corps of Engineers), not really a new miracle product, just new(ish) packaging, delivery, and trendy label. Concrete is an excellent building material, but as someone else pointed out elsewhere in these comments, it's hard to regulate quality, moisture, etc, on-site (not to mention site access limitations and the costs of setting up and maintaining the delivery system). They made a good case for more affordable, flexible, and quality controllable prefabricated materials already available and in use. Transportation costs are going to be similar as well, since a similar amount of any building material would have to be brought to the site, and in the case of "3D printing" you're also moving the massive apparatus both to and from the site.
Maybe someday, but this just isn't ready for prime time or budget housing. Aesthetically, it's interesting and looks nice. Right now, that's the best argument for it, if buyers prefer this aesthetic over others.
I want to know the destructive testing done for structural integrity
People will believe anything as long as you market it skillfully. Just look at Tesla.
Haha where is there a construction automation forum? I have so many ideas about 3D printers.
I’ll have to make a free public forum on my site! Email me jarett@3dprinted.construction if you want to help me and be a moderator!
Maybe we should use discord or Reddit… lmk your thoughts!
"3D printing" carries tons of terrible conceptional baggage. The phrase should be "digital placement", it does not matter at all whether it's placed by a nozzle or not. Dimensionality reduction is not the way forward.
In the Los Angeles area of California, who (company or group) would you recommend hiring to print a house?
It depends what you mean by print the house if you want to print it on site in concrete, Emergent is the only girl by November in California doing that with houses right now. They have some projects in northern California. I also know of a couple groups in LA that have concrete printers, RIC may be starting building projects soon and rumor has it Winsun will be starting construction projects in LA as well.
How is it cheaper than regular CMU blocks ?? Just the labor costs?? Surely it's using more grout/concrete than the standard wall thickness of CMUs ---
Its like NFTs - i just don't understand where the "savings" comes in - the block "masons" are just a small fraction of the price of the home
How strong is a thin multi-layer unreinforced concrete wall?
I would assume not to strong at all
There are many different types of 3d printer construction robots and designs. It's still cheaper faster and more efficient than regular homes. Especially in a society where most people are poor. This and many other technologies, will make our world far better.
No the whole point of this video is to explain nobody has shown evidence that it’s faster or cheaper.
@@automateconstruction I get it. But I also get the facts.
@@automateconstruction for what's involved, it should be far cheaper. If the government wants to screw people like they have many times, then yeah, they'll make 3d printed residences more expensive. They don't want better and cheaper tech out there. It goes against their greed fake power and control issues.
@@caseyford3368 What facts are you referring to I would love to read into it.
@@automateconstruction as it explains in the video and others, it depends on what material your using. Each 3d printed homes price, would be subjective. It depends on what is used to make it.
This is why I love science and technology
Today's materials are tomorrow's problems, everyone who has worked in construction is aware of that saying, I see many issues with these but an obvious one is expansion joints, All concrete needs an expansion joint, floor slabs, even roads, but a south facing wall with expand and contract a lot, thin walls must be prone to cracking, moss on north facing walls in the northern hemisphere will be horrendous with that amount of texture, compression failure after a certain height and weight has been reached,. I'm all for new techniques but they need to be cheaper than this and compete with conventional buildings, brick walls, tiled roofs, wooden joists, its taken years of trial and error to get to the best method of building,
Innovation is not cheap. When the process is refined, the wrinkles ironed out (no pun intended) and roll out expanded, prices will come down.
It has always seemed like 3d printed houses address creating the shell of the house, where the bulk of the cost is in labor and materials is in the plumbing, heating, and electrical systems. In any case, reducing the cost of construction is irrelevant to housing pricing for consumers. It just alters the amount that is split up between municipalities, speculators, and contractors. You can't have cheap housing or that will destroy the property values of existing owners. As long as zoning laws, land use regulations, licensing requirements, and other such restrict the supply of housing, and central banks manipulate interest rates to keep a guaranteed amount of housing inflation, rent will be high, and overall a lot of the economy will be directed towards housing.
Hasn't this technology matured yet to the point where they can eliminate that annoying horizontal ribbing from the printer layering? All I can see is crevice upon crevice for dust to collect on both inside and outside wall surfaces. It's still at the novelty phase.
Eventually yea by using a mold in the place so it dries straight. And I am sure eventually they will add the quicklime Roman ingredient that preserved concrete by allowing it to self heal cracks
A render can be applied. I saw another video where that was done to the outside and the inside walls.
OK, guys. I am sure most people don't expect their 3D printed home to be $10,000. Builders have an idea how much it cost to build a 3D printed home do they not? Just give the buyer an estimate cost per square feet. Everybody know it is still a new technology and price will change over time. Why make it sound so dramatic?
It is the future. Especially here in Europe where stick houses never became popular. Majority of housing is built from prefabs, cinder blocks or bricks.
So can this be renting out in any state?
