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.

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.

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.

[@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.

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.

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.

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.

[@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.

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

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.

"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.

whats the cheapest house 3d printer in the market, does anyone know?

[@menons4republic476]

Jarret Thank you. You just answered all . What about other materials than concrete, like the mighty buildings have

[@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?

[@Sherirose1]

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]

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.

[@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...

@@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.

[@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.

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.

[@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]

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

[@michaeljames5936]

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.)

[@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.

[@_melvonty]

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!

[@joemartino6976]

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.

[@Talpiot8200]

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.
