11 Lies of the 3D Printed House | EXPOSING THE TRUTH of Printed Construction

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.

[@phil562]

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.

[@automateconstruction]

[@bobdinitto]

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.

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.

[@316lvmnoneofyourbusiness7]

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.

Really appreciate the information provided! Wish the media could approach as you do! Thank you!

[@itoibo4208]

"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.

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

[@itoibo4208]

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.

[@kcgunesq]

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.

[@kellyplandel3253]

You could plaster the walls fairly easily and make a smooth finish which would make sense to prevent dust and germ buildup.

[@axelpalfy7597]

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

[@egcruzer]

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.

[@rogermccaslin5963]

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.

[@beegee22]

@@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.

[@zantezaint2348]

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 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.

[@dobertjowneyrunior3023]

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.

[@josephfra2456]

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?

[@berryreading4809]

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 🤨😉👍

[@liammapps123]

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.

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?

[@automateconstruction]

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.

[@iac4357]

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 !

[@itoibo4208]

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.

[@itoibo4208]

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

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..

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

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.)

Wow! Imagine how many trees could be saved!

[@realjettlag]

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.

[@thecsucihai]

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?

[@JohnVKaravitis]

Isn't it cheaper to have a factory-built house delivered and assembled on site?

[@itoibo4208]

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.

[@S3l3ct1ve]

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

[@aaronb8698]

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.

[@MicMaine]

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...

[@MicMaine]

@@francescocerioni8939 isn't that what real 3-d printers have, a box surrounding them?

[@Ponen77]

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.

[@eddybrevet6816]

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

[@cchavezjr7]

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?

[@itoibo4208]

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.

[@trashman1358]

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.

[@automateconstruction]

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.

[@itoibo4208]

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

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.

Great video. So far I see zero material benefit in this technology.

[@richdobbs6595]

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.

[@BracaPhoto]

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

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.

[@repalmore]

@@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.
