- Stephan Mansour is writing the ISO/ASTM code for 3D printed houses so I had him on to separate truth from fiction. Keep in mind some of these myths may come true in the future, we just haven't seen evidence of them yet.

As with all technologies, healthy skepticism is needed.
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.
Has anyone built one of these 3D printed houses on a hydraulic shake table? This Architect would like to know...
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
Pumpicecrete and pumicecrete accessories.
V be a da
Pumice mordar is used in hia Sofia which has survived 1500 years and terrible earthquakes
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?🤔
@@Limbodaramus the main place pumicecrete is done is in New Mexico
Pumicecrete works in all climates
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!
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.
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!
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.
@@nobreighner 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.
It blows my mind reading these comments. It's as if nobody talking has seen industries emerge, innovate, stabilize, and then commercialize in their lifetimes. Ever heard of "manufactured houses"? People were afraid of those too.
The future will be made with stick built homes, monolithic concrete domes, printed houses, factory built houses, kit houses, and probably stuff we haven't even seen yet.
Where stick built makes sense, there will be profit and customers. Where there are tornados, hurricanes and fires, there will be a market for concrete. Where there is need for speed, and cost savings, there will be factory houses. Have no fear, you can chose your own adventure.
Yeah so true well said
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 👊🏻
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
I was really wondering about this! Thanks for the program, thanks for the work.
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,
I don't see a thermal break.
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 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.
Really appreciate the information provided!
Wish the media could approach as you do!
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.
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?
@@dayzplayer8539 bs. you can say that about any housing
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
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.
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.
Jarret Thank you. You just answered all . What about other materials than concrete, like the mighty buildings have
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.
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!
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.
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.
Click bait "Lies!!" . It's just sales for his own program
It’s more than that, it’s an interview with the guy writing the ASTM standards for 3dcp that means something.
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!
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?
Thank you for your valuable information. I truly appreciate it because it seems too good to be true and I tell you where I live that equipment couldn't even fit up here unless you brought. It piece by piece an et cetera
Great video, thanks for the information. Would it be much of a savings if just the outer shell was printed and the interior was stick built, making it easier for the trades?
That's actually supposed to be one of the largest labor/other material costs of this whole concept... hollow interior walls for running emt/low voltage/pex (bath/kitchen areas on exterior walls have even more specifics), PT framing is installed in door/window openings for mostly conventional installation, slab to top plate rod tied owns to cnc cut top plates for wood trusses, basically only the ceiling, areas above doors, and other random areas require drywall hanging/finishing... If designed right they in theory are easy to modify or remodel in the future.... Although I definitely see a future where everyone wants their soft serve walls stripped and covered with deywall/shiplap/t&g/etc 🤣 adding lots of labor and material costs while backtracking on many of the current "selling points"... I guess time will tell 🤨😉👍
definitely will see people filling in the gaps with filler to make the walls smooth. ngl, i like the look of this concrete but it also looks like a dusting and cleaning nightmare. @@berryreading4809
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.
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.
How do they hold up in an earthquake? Varying magnitudes, durations, of course.
Hello there, please do you have any idea how one can buy the 3D printer machine?
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
Like most new technologies there are some teething issues and thanks for sharing them 👍🏻 Guess they will be sorted out over time or it will not make it
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
Yeah there has to be some sort of algorithm the machine can take into account to modify the mix
How would they run wiring ducting and plumbing through walls in this?
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
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
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.
Container and 3D Printed is a good combination... Really cool
Huh? Container construction is lame as hell.
Print the container.
Why didn’t he discuss more of the price in details
I love your balanced approach to this interesting topic.
Jesus its so hard to find peer review and critique from the huge mass of marketing and promotions that have been vomited out.
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.
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.
In the videos I'm only seeing ground floor 3dprinted but not the first floor. Please explain.
What is the actual print material? Is it actually concrete or something else?
Awesome video, but how about the Elephant in the building? Acoustics, acoustics, acoustics. :-)
surface geometry
Like everything the hidden costs will never be shown until they hand you the bill.
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.
I want to know the destructive testing done for structural integrity
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
Plug in play Spool in electronic plumbing and H vac assembly inagratin with sip pre fab roofing all installed off same inclosed gantry.
Maybe this is the type
Of construction needed for areas such as Florida. We do construct using concrete post Andrew and it’s been what let’s us withstand Categories higher than 2. The question is how the windows, and ceiling are constructed as well and tied to the structure.
Marvelous design!
In what location is have those house design?
+1👍thanks for your continued efforts in bringing the info 💪 interested in this subject as a client/homeowner
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).
👉💯👈👏
THANK YOU GUYS FOR THIS VIDEO.
They should print and fill the forms with traditional cement, then break them off at the end
All 11 points agreed! The frustration I have is always the misunderstanding that 3DCP is easy!
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.
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.
How strong is a thin multi-layer unreinforced concrete wall?
I would assume not to strong at all
So can this be renting out in any state?
5:10 Need to build an extruder head that has heating elements. This will make the materials tempurature more consistant and help activate curing.
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.
Sounds like the industry has some growing to do and then will hopefully sort itself out.
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.
My question is how do you get the Electrical Plumbing and insulation into a 3D printed house wall?
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
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.
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.
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
Nothing is faster than a tilt up building
The drawback is steel beams are needed
That being said, perhaps 3d printed homes and the tilt up design can be combined
The base structure being tilt up with 3d printed sections that have certain angles or overhangs that can't be poured on the ground
Honestly, I'm not a fan of the layer lines on a 3d printed house either
Leaving the layers exposed just looks unfinished to me and is basically just bragging about the fact it's not traditionally built
It would be more impressive if you couldn't tell so much that a house was built via traditional carpentry methods/ pre fab, or if the home was built in an untraditional manner using renewable/recycled resources
I doubt we'll be 3d printing old rubber tires into houses anytime soon but we can 3d print polymers with wood fibers 🤔
We are just scratching the surface on 3d printed houses, I don't think a proprietary mix of material (basically concrete) is the way to go
I fix commercial reefers in concrete yards because throwing ice in the mix makes it set quicker and more densely, now they are using liquid nitrogen
Polymers infused with concrete might be an interesting way to go, that would be one heck of an extruder and hot end though lol
Pumping out layers of concrete is the beginning, printing infused polymers on an industrial scale using recycled ♻️ plastics might be the next step
The bottom is the ground floor which is Y
The Y axis stays stationary and the X,Y,Z axis movements are all done via a 3 point frame that moves X Y while the Z is just the hight moving up
A giant portable, modular, bed slinger where the bed doesn't move
Set up the equipment using crane trucks, print the home, disassemble the gantry system, set it up where the next house goes and print away
The biggest drawback is being carpenters and framers working as a team are incredibly fast and efficient
There's needs to be a niche that goes beyond just the 3d printed part
Automation is just getting started! I think you are at on the right track but I do think automation will be the best solution in the long term. The only big question is when it gets there.
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?
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.
With all those curtains in your room, how is your room not sound treated? Still getting lots of reverb
This is why I love science and technology
Thanks for enlighted us. I think 3DPC might be useful for build military bases(in warzones).
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.
Where can this 3D printer be bought, and do they give you a course to operate the machine?
Check out all my other videos they highlight the awesome companies selling printers!
Yeah, it is in it's infancy, but Lloyd Wright would have given his eye teeth for this technology.
So if 3D printed homes cost the same or more than traditional construction... The benefits of a 3D printed home is what exactly?
Aesthitics? Bragging rights? Feeling all special inside for being quirky? I've wondered the same.
"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.
I wish they wouldn't call it printing. It's machine manufacturing.
Nice video buddy and gl with the channel. I do feel that business does - after too long if you ask me - notice bottlenecks and looks to 'iron' them out. I'd like to ask the question, of the difficulties you see in 3d printing, which problems do you believe cannot be automated? For instance, the mixing, waste and delivery of the concrete. Agreed, it will take time, but I cannot help but believe all of these processes (based on sensors checking the site's weather, temperature, humidity, sun intensity, etc) can be automated and make the mixture to suit. 2. Observation. CCTV cameras can do facial recognition, read number plates... Knowing we already have the architectural drawings (maybe designed by AI?) I don't think it's that big a stretch to set up 4 cctv cameras to watch the print to ensure a successful build. I think it's strange that we've come up with AI, 3d printing, self driving cars, etc and everyone is critiquing them as if: This is the end product. Chatgpt is still in open beta. Things take time. But cast your mind 20, 50 years into the future. What do you think a 3d house printing site will look like then? I mean, I don't even think the lorry making deliveries will have a person involved at any stage: AI will scan all manufacturers to buy proven products at the lowest price based on time scales required, these products will be loaded onto the lorry by automated fork lift trucks (or a futuristic variant based on AI efficiency design), the lorry will automatically drive to the site and make the delivery, returning to it's home depot once done. I do like your title - you've got to get those views in, including mine - but I think the actual title of this piece is: "3D printing. Where we are now." But nice one Jarett and all the very best for the future.
Thanks! To try and answer your question, I have to preface by saying I don’t have the best grasp on which tasks can, and can’t be easily automated. Apparently things like manipulating fine wires into particular places is challenging due to the way they tend to fall or tangle randomly. I have no intuition for which tasks are easier or more difficult for a robot to do on site, there is just so much left to automate. I know that’s not much of an answer so I’ll give you a crapshoot anyway, just a guess. I think that details are going to become cheap to implement however, plumbing and electrical is likely to take longer to automate. Spray foam insulation also requires a fine touch along with other types of Louisville commonly used with 3d Printing concrete. Beyond that there’s a whole host of tasks that are just easier for a person to do their machine at this stage. If you look at the number of robots on the manufacturing floor of Teslas, Fremont facility, it initially ballooned, and then was drastically reduced when they realize they tried to overhaul the meat. They got rid of a ton of bots, then started replacing them slowly, but there is a such thing as over automation, or at least automating to quickly. I hope that approaches in answer to your question.
all a matter of how badly they want it. often it comes down to money. could we build a bot that lays in pipes and wiring, yes. would it be expensive to design? yes. would local codes even allow it? questionable. you also need people who are creative. i saw a bot being used for making parts and it was not being used to its full capabilities because the people at the plant were still living in the 20th century, mentally.@@automateconstruction
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!
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.)
whats the cheapest house 3d printer in the market, does anyone know?
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.
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.
what happens if there a huge crack? there's no rebar or anything that reenforce like in concrete
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
Where could I go to buy the system for 3d . Let’s work
Very informative video. I would like to get a 3d printed house. However, they are not ready for prime time yet (price-wise). Eventually, the price will come down and the building process will get better. I would like to see 3d printed houses built in Illinois and see how well it can survive severe weather like a Tornado.
Yeah that’s true. So few people understand this. It’s so refreshing to read this comment.
Great interview! What house is shown when you are talking about 4) just add water (5:17) ? is there a way to find more about that project?
That’s the milestone project I visited it in Eindhoven you can watch the tour on my TH-cam 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.
@@automateconstruction Yeah, its this one: th-cam.com/video/NQ_yRnWms3g/w-d-xo.html
@@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!
