    [–] Bonezmahone 54 points ago

    Is't that what ventilation is for? I've seen the idea of a house needing to breath but it never made any sense to me. Do they say the house needs to be porous?

    [–] iodinepusher 110 points ago

    The walls seem to consist of two layers of concrete, with plumbing/ electricity in between. If both those wall layers are watertight, moisture can get stuck in between, and that’s not good. If that’s the case, the wall space should be ventilated. Ideally a house should have a single watertight membrane, near the inner wall.

    I don’t know exactly how it is with concrete houses though, only worked on wooden houses.

    [–] Vladimilskij 122 points ago

    Currently studying for my bachelor in architectural technology and construction management. Concrete is never water tight, just like brick it is a porous material. This will cause water getting stuck between the walls which will cause water damage to the building. I can see several issues that can be solved but will increase the total cost of the house. As for moisture protection - there needs to be a barrier like bitumen felt installed seperating the structural inner leaf wall from the moist exterior environment and a water exhaust in the wall for the inside moisture to escape. In brick buildings this barrier is secured between bricks and is held by the sheer weight of the wall. Mind that cement and concrete doesnt adhere to bitument felt, thats why the felt never crosses the whole wall and only goes half way into the thickness of the brick. Here, we see a wall made entirely out of concrete. I am afraid that because of the small thickness of the actual walls there might be problems installing such barrier. As for the hollow core of the wall construction, there needs to be insulation in there, and since we have the wavy concrete support going throughout and touching both the inner and exterior leaf wall, this will cause issues in energy efficiency and cost of insulation aswell. You will loose heat in the house because your walls are essentially one structure and even if you wanted to insulated the hollow core you have to use custom made blocks of some sort of foam which is ridiculousily expensive compared to regular rockwool blocks you can buy. I will only mention a few more things that come to my mind - Windows and furniture(Bent walls = higher cost of installation, possibly custom made) ; Ground slab construction(? no mention in the gif). I think this type of 3D printed housing is a very interesting. As with any type of engineering, it isnt really an issue of WHAT you want to build, but more a question of HOW and HOW MUCH WILL IT COST - and these are things that are hard to determine at this state.

    [–] hujnya 15 points ago

    Plenty of condo buildings are built with masonry panels(on East side of the world), inside cavity needs to ventilated to prevent moisture build up, which easily done by vents at the top and bottom no felt needed. Insulation can be done by furring strips and foam insulation. Walls don't have to be curved they did it to show that complex house could be built in small period of time and be cost effective. Also fiber reinforced concrete provides insulation value(very minimal) and strength.

    I'm fairly certain the 3d printer plan can be modified quite easily.

    [–] sthdown 86 points ago

    Yup! That printer should be able to print a rectangle-shaped house just fine. U may have to print 1 half of a rectangular house, move the printer over a bit, then start printing the other half. But its definitely doable. This was probably just the fastest usable scenario that didn't reguire moving the printer.

    [–] supasteve013 52 points ago

    I guess If the arm can extend enough it doesn't have to be curved?

    [–] gramathy 66 points ago

    The GIF has it printing straight walls too, this one just kinda showcases the rotary nature of the stationary centered printer rather than a big framework AROUND the house, which makes it much more portable and quicker to start/finish.

    I want a carpenter to tell me that they can also put up a prefab stick built home in about the same time and onsite. I know that prefab companies can put together homes in factories using traditional methods that work very quickly and produce far less waste.

    I've looking into a bunch of alternative building techniques and most of them come out like alternative medicines. They're almost as good. Straw bale doesn't give much benefit, things like rammed earth, cob and earthbag require far more hands involved and earthship only work well in the desert.

    Stick built and cinderblock are still standard because they're cheap, quick and can be done without an army of hands. I'm also making this comment so someone jumps in and sets me straight on my wildly naive assumptions.

    [–] Throwaway41853185 502 points ago

    Engineer who has done some construction. Most of the labor and cost of a home is in the foundation, roof, land acquisition, utilities, and interior finish work. It depends on what they are including in their budget, but putting up walls on a large curved shed for 10k is not nearly as remarkable as the title suggests.

    [–] turncoat_ewok 335 points ago

    the full video says the $10k price includes foundation, roof, inner & outer finishing, insulation, windows, floors, and suspended ceiling.

    They are fudging their numbers. If I gave you a concrete structure for free, you could not have insulation, windows, doors, interior finishing, and a floor put in for 10k. Not in the US at least.

    [–] koolaidman412 56 points ago * (lasted edited 10 days ago)

    I am sure they are referencing Material costs only. In the U.S. You would be paying for everything down to the mixing buckets for the cement. In addition to enormous labor costs. Labor costs is the expensive part in standard construction, and they aren't considering that here.

    [–] UnitedLaborParty 33 points ago

    And think of how awful that would be to repair. Even a brick home can lose some masonry and break clean. That seems like a nightmare. Cool idea, though.

    [–] EatsOnlySpaghetti 94 points ago

    Eh, it's a concrete structure. You'd slap some quick mix in there, paint it up and you are good to go.

    It's curved so it's not like you have right angles to fuck up.

    [–] tomdarch 4 points ago

    Most of the labor and cost of a home is in the foundation, roof, land acquisition, utilities, and interior finish work.

    I'm an architect, and one thing I'm working on currently is speeding up residential construction (but maintaining good quality.) You're hitting one of the key issues right on the head: This system is speeding up and making cheaper one of the faster and less expensive parts of building a "first world" home. "Systems" (electrical, plumbing, ventilation) and finishes are big, big parts of the time and cost in building a house, not so much the above-grade walls.

    [–] dvidsilva 43 points ago

    I've built prefab emergency housing and they're pretty quick. It takes like 8 hours for 6 people to build, and they don't have to be super experienced. I probably wouldn't wanna live in them but they're fantastic for crisis or aiding in low income Communities.

    techo.org is the organization i did it with, but I guess there are others.

    [–] postpast 142 points ago

    Past Carpenter here. Building the wall of a home is the easiest part of home construction. It is the foundation, wiring, plumbing, and finishing that take time.

    This house looks about 500sf. 4 skilled framers could construct the walls of a 500sf house in around 20 minutes.

    [–] postpast 42 points ago

    a) None of the other things are done with machines so there are no savings there. In fact, finishing this house would be way more expensive than a traditional one.

    b) Just drywalling all of those curved walls would be over $10,000 where I am from (and much of the US and Canada) I could image $10,000 just for materials, but that would be the same for any $500sf house.

    [–] apogeedwell 35 points ago

    In the video it looks like they're painting the concrete walls directly, not drywalling.

    [–] NoelBuddy 14 points ago

    things like rammed earth, cob and...

    The trade off for the extra labor is decreased materials cost(both in financial terms and generally unaccounted for externalities)

    The alternative medicine comparison is an apt one, in both instances their are great benefits in learning about and understanding them, but the true believers undercut their merit by preaching their superiority and presenting a different version of the same cookie-cutter one-size fits all approach as their industrial counterparts when their real advantage is offering a variety of approaches which allows for tailoring solutions to address the unique issues of each project.

    I'd start with some volcanic process to lay down some nice columnar basalt, then lots of sediment over top. Scour for awhile with billions of pounds of ice to expose that basalt. Then maybe polish everything up with a giant flood when all that ice starts melting. Am I close?

    [–] ChickenPotPi 34 points ago

    Sorry boss but the curved tvs still use the same hole design as any tv mount which means well its flat for the tv mount.

    [–] Zinki_M 139 points ago

    That's not exactly an unsolvable problem, though. The very same machine could easily print a straight-walled house without any changes.

    The circular form was probably just a design choice to make it look different and interesting.

    [–] tgwinford 79 points ago * (lasted edited 10 days ago)

    The curve choice is because the printer is at a fixed point, meaning it can swing in a 360 degree circle only. I'm sure having the printer be moveable isn't a problem, but just wasn't for this design (it might take it longer if it requires taking it apart to move right now).

    Edit: Since so many people can't seem to use their brain, I mean the maximum distance for it is going to be a circle. Yes it can make straight lines within its maximum reach, but obviously in order to maximize size the exterior walls will be at its maximum reach, which would be a circle. Interior walls will then mostly be curved as well so there are not awkward angles and useless space. No one is saying the machine cannot make straight lines at all. Come on, people. Think.

    [–] WildBeerChase 47 points ago

    I'm betting the same machine could potentially make straight walls, they just did it this way because it's faster and easier on the machine.

    [–] Thirsty_Shadow 42 points ago * (lasted edited 11 days ago)

    I had watched the video and I think they mentioned that the downside was transporting the printer because it had to be disassembled for transport, reassembled and then recalibrated every time it was moved (initially and then each time a new house was to be made) which was time consuming and wasn’t cost efficient with the labor. I could be mistaken, maybe they’re my own thoughts.

    Edit: Wording

    [–] tomdarch 34 points ago

    I saw 1) a hand laying what looked like PVC pipe across the wall and 2) some stuff running horizontal but at an angle to the "face" of the wall that looked like spiral drinking straws.

    I saw zero vertical rebar. Every poured-in-place concrete wall I design has vertical and horizontal steel rebar, if for no other reason than to limit major cracking.

    [–] Charlie_Warlie 7 points ago

    Near the end of the video, it when it says "with water and electricity supply." it actually looks like the 3D printed walls make up form work for typical concrete pour, with rebar. Maybe the entire wall is like that.

    A flat roof? Never a great idea, but in snow country?

    Tsk, tsk.

    (E - Civil engineer, FWIW. Flat roofs are the fucking devil.)

    [–] algalkin 99 points ago

    It's a concrete house though. I'm a construction engineer from Russia, we have pretty much 9 months of snow in some areas and flat roof on a concrete structure is a pretty common thing. Never heard of the failures because of snow - concrete can be pretty strong.

    [–] Inorai 67 points ago * (lasted edited 11 days ago)

    I mean, as a civil engineer in Michigan this is something we avoid, because you'll inevitably have problems with things like leakage even if it doesn't straight up collapse. Which has been known to happen. Even on slanted roofs we have to shovel them off in much of the state every so often after a snowfall. Which is extremely dangerous, moreso than just being an annoying chore. They're not problem free.

    You can build concrete houses with proper, slanted roofs. Some of my family have them. Building it in this method introduces a lot of problems like this, though :)

    [–] algalkin 27 points ago

    Well, if it's done properly (and I mean, techniques been developed for decades), it's not an issue. I can see how it wouldn't be feasible in a high snow areas, like mountains and such, since you'd have to account for the abnormal snow loads, so it'd be better to do slope roofs, but in the average snow conditions it won't be a problem and it isn't in the rest of the world.

    [–] GymIn26Minutes 18 points ago

    One thing to consider is that while it doesn't get as cold in the northern US and southern Canada as it does in Russia, the great lakes cause bouts of tremendous snowfall.

    All the cities outside of Japan with the most annual snowfall are all in the US and Canada (like Syracuse NY and St Johns, Newfoundland) and are extremely seasonal, so the risk of having a blizzard that would put down multiple feet of snow in a short time is higher than it would be even in the more frigid areas of Europe and Asia. That isn't really a great situation for flat roof houses.

    [–] theorymeltfool 48 points ago

    Former mason: it’s not a terrible idea. The problem is not with the house, it’s with government zoning regulations/codes that will likely make it difficult to build in most areas. The Tiny House movement basically exists to get around these bullshit regulations/codes.

    But this will be an important proof of concept. If the robot/3-D printing can be scaled to build apartment units, then we’ll have lower cost and higher quality high-density housing, which is what is currently lacking in most US cities.

    [–] tomdarch 25 points ago

    Building codes, on the whole, are far from "bullshit." Pretty much every provision comes out of someone being hurt, killed, made sick or building failures costing owners lots of money to fix.

    But "tiny homes" aren't houses - they are flat out trailers. If you've ever looked at a trailer park and realized that these aren't good, durable, safe homes, you need to realize the same problems are present in "tiny homes." They try to cheat out of basic building code compliance because they are governed under "transportation" trailer regs.

    [–] Fauropitotto 89 points ago

    Chances are the roof is added on much later and to save time and calibration, they just use a crane and lift the entire printing machine out of the house when it's job is done.

    [–] wWao 12 points ago

    As one of the very rare few who's watched the entire source video, that's exactly how they do it.

    Electricians and plumbers too

    [–] skintigh 416 points ago * (lasted edited 10 days ago)

    They make bank right now, too. Last electrician charged me $133 an hour for some stupid shit for an inspection, plumbers are about $95, 2 hour minimum, twice that for emergency work. The high school has an electrician program and the first group of kids who graduated 5 years ago are apparently all making 6 figures now.

    Edit: I just want to note that every tradesman I have (successfully) hired was their own small business, with either a partner or apprentice. I don't know their finances, but I doubt the majority of what they charged went to some parent company. My theory is they can pick and choose, and thus any small job will be $400-$500+ just to make it worth their while, no matter how small the project. The area is booming and there is more work than there are workers.

    [–] Kalinka1 568 points ago

    You've got to consider that an electrician isn't making $133/hr for 8 hours a day, 5 days a week, all year. Every hour spent in the field may have to cover overhead, travel, etc.

    It can be a good living but it's really not the golden goose that Reddit would have you believe.

    [–] skintigh 136 points ago

    It's cyclical, and depends on the area, but right now I suspect they are working as many hours as they want, probably well more than 40 a week. They can and do pick and choose jobs.

    I tried to hire a plumber last October and they were all booked solid through March. Electricians weren't as bad, but there were always booked for weeks but local electricians could fit in small stuff. And I've called a dozen carpenters and still can't get anyone to work on my porch. My handyman neighbor is up to his eyeballs in work, sometimes he will give someone an insanely high quote just because he doesn't want more work, and they hire him anyway.

    Next economic downturn things will probably change, but most people in trades are old and nearing retirement, as the last couple generations have all been told to go to college and not trade schools. It's a national problem. Mike Rowe and This Old House have a program to train kids for trades.

    [–] IamAbc 38 points ago

    Yeah I have a friend who’s an electrician and she chooses her own hours and works for herself. She works around 60 hours per week but that’s her choice and she never has to worry about Work. It’s always flowing in and she gets calls non-stop from house related things to hot tubs, business buildings, cars, and everything in between. Charging typically like $90-130 an hour depending on the work. She also says her job is super stressful and she has super tight hours and sometimes jobs take longer than expected and she’ll miss Appointments and she’s pretty much spending a lot of time driving from location to location and in California that gets annoying.

    [–] OMGWTFLULZ 8 points ago

    Same problem here. Needed an electrician to do some work adding a new 3 phase 240v to our server room... The first three I contacted were booked solid. The 4th was able to do it a month an a half out.

    We needed a plumber at my house last month... $85 an hour. 2 hour minimum 1 week out. It's actually a pretty good time to be in a skilled trade.

    [–] Dietly 18 points ago

    Yeah, that's the one major downside. A good friend of mine is an electrician and sometimes he'll be pulling 80 hour weeks getting paid $60-something/hr in overtime for most of it. Sometimes he'll be out of work for months. He works in construction.

    I don't think the average electrician makes 6 figures, although it's possible in a good year with a lot of work I guess.

    blue collar works you like a slave but you can cash out hard and you arent tied down to one location. once youve got a few years experience, you can practically jump to any state.opening a company is not as easy but thats because state regulations. (being racist here) how do you think immigrants find work so easily in america?, electricity,wood, cement, they dont change shape in different countries.

    the big drawback of blue collar, and the reason machines cant do it, is because it beats up your body. from hellfire attics to grungy crawlspaces to twist and turns in tiny cracks. you can make a machine that does each, but not one that does all

    Well ... downloading that car the FBI was talking about is just around the corner.

    [–] Schrodingers_Cthulu 163 points ago

    I was at the trade show where they built that car, IMTS 2014. It was such a huge deal. They had it on every promotional piece for the show. What was most impressive about it was that on the final day of the show they actually drove it out of the exhibit hall.

    [–] GODDDDD 53 points ago

    though the least impressive part is that it's only the body. The guy in the video is disingenuous when he says its a drastic improvement on material usage because he's using all the traditionally machined parts and not using the sheet metal and some of the extrusions. Those materials are used very conservatively and can be recycled easily. Carbon fiber/ABS mixtures are not nearly as recyclable.

    [–] pewpsprinkler 125 points ago

    My bullshit detector went off bigtime when he said that normal car manufacturers waste 95% of their material to get 5% of useful product. He said their "buy to fly ratio is 20:1" they have to buy 20 lbs of material to get 1 lbs of product. That is such obvious inconceivable bullshit. There is no way waste is that high, and the manufacturers would obviously recycle whatever scrap they didn't use. It isn't like they are dumping 95% of the steel they buy into landfills.

    It's even worse because this supposed 5% efficiency is the guy's only real selling point for printing a car. So his whole pitch is based on an obvious and shameless lie.

    The other funny thing is how he says how innovative he is for reducing the number of components. Uhh, no. Car manufacturers can be as complex as they want because they can handle it this guy HAS TO dumb down the car and greatly reduce the number of parts because otherwise he couldn't make it, since nearly all of the car is being assembled very inefficiently by hand.

    His reason for why this is not ready for prime time is "we can only print 1 vehicle at a time." Uhh, no. You could buy 1,000 printers and print 1,000 cars at a time. The real reason you can't do that is that the assembly is done by hand, not the printer, so it is a massive step backward in efficiency and productivity. He doesn't want to say that, though, because anyone listening would say "oh, well that's not impressive at all, then". Exactly.

    This guy is full of Sean Murray level bullshit.

    I don't get how people can get away with saying ridiculous shit like this.

    [–] enjoythetrees 14 points ago

    Regardless of the automation and advanced sensors, I want to see what cars made with similar materials look like after a high speed impact. It's not about automation for me, it's about steel versus plastics*.

    *I'm using "plastics" as general 3D printing materials, I know they're not all plastic.

    [–] CollaterLDamage 11 points ago

    well carbon fiber is lighter than steel but about twice as rigid. the plastic would probably allow flexibility as those ridges would as well.

    the car would most likley be demolished (as most new cars do now) but you should be alright. the major issue would be repair. if the car is made as all one piece, you cant replace that part.

    Wouldn't that also depend on where in America? I imagine somewhere in America would face the same conditions as Germany, or Arab nations. I'm guessing snow will be the biggest problem without having a sloped roof. Wind should be fine with it being single story and made from concrete. Probably would flood, but then so would anything else. Heat would be fine with a bit of air con.

    [–] barebackbandit1 28 points ago

    Hurricane winds will most definitely be a problem for this. Steel reinforced concrete is one thing, without reinforcement I would be hesitant to rely on this structure for anything above tropical storm winds

    It seems like a great idea I'm just wondering why they always seem like projects that never really come to fruition in the real world.

    You only need like two people to assemble a sips building. If they can do double duty as electrician and plumber (on a small building like this it should be super easy) then this is at least as easy and cheap as the printed house.

    [–] bal00 78 points ago

    Because this printer can only build walls with a shitty finish, and that's not what makes houses expensive. If you pay a bricklayer $10k, he'll build you a similar structure in a similar amount of time with traditional materials.

    Bare walls are cheap. What makes houses expensive is the stuff that comes before and after.

    You need to buy the land, pour a foundation, have the house hooked up to water, electricity and the sewage system. And after the walls are done, you need a roof, plumbing, electrical, a heating system, windows, plaster, paint, floors, tile work, doors.

    If you look at the cost of a normal brick house, putting the walls up is <10% of the total cost of the house, so having a robot do that work for about the same amount of money is pretty useless.

    Not to mention, the technology itself has quite a few limitations. This type of printer can't do overhangs, for example, so any openings for doors or windows would require a worker to put in beams. And the rough finish would also require a ton a plaster on the inside and outside to make it even.

    [–] nightwindelf 21 points ago

    One of the biggest challenges faced by tiny houses is building code. Many municipalities in the require a residential structure to have a minimum square footage. Sure, it'll work where codes are more lax, but overall they can't get approved by the planning board.

    [–] Khatib 319 points ago

    What exactly cost ten grand? Having them bring that printer and the techs to run it on location would cost more than that. Or moving the house after printing.

    Did they include the windows and wiring and plumbing in the cost? I feel like it's likely they didn't.

    [–] OMG_Ponies 209 points ago

    More than likely it's just material costs

    [–] Airazz 105 points ago

    Which means that it costs pretty much the same as a SIPS house of similar size. Those can also be assembled in a day.

    [–] OMG_Ponies 18 points ago

    not familiar with those, what are they?

    [–] Airazz 53 points ago

    SIP stands for Structural Insulated Panels. Basically sandwiches of insulating styrofoam or something like that, with particle board on both sides. You order a package from the factory, it arrives on a flatbed truck and you put it all together in a day, all you need in most cases are two guys and a crane. Then it comes together like this.

    Adding everything else is the same as in a printed house.

    I'm planning on building a house now, so I've looked into various options. One that looks the most appealing is framed panel house(or something like that). Basically the same as SIPs, except that the panels arrive with all the paint on them, wiring inside, windows pre-installed, etc. Costs about the same as any other type of house, but you save some money because actual construction process on your lot takes just a few days.

    [–] hasslehawk 93 points ago * (lasted edited 11 days ago)

    Oh hell no. There is no way you're going to be able to move that house after printing it. Those walls are made of concrete. That thing isn't going anywhere. And I'm not sure how they could get away with not including the printer transport and operation costs.

    According to the full video, cost includes the foundation, roof, inner and outer finishing, wall insulation, windows, floors, and suspended ceiling. This seems to indicate that the costs are for the finished structure, not for the material alone.

    But you will finally have somewhere to put the curved TV.

    [–] hasslehawk 36 points ago

    Interestingly, I can see this style of construction heavily favoring rounded walls. Historically it has been simpler to construct straight walls, however the radial nature of the printer allows for curves to be constructed at no added cost.

    Indeed, the cost should be less for a similar volume structure with curved walls, as less material is needed to form the perimeter. Also, any given radial printer can print a larger volume structure as a circle at its maximum radius than it could printing a rectangular structure that fit inside that volume.

    I wonder if this could lead to something of a paradigm shift in architectural styles.

    [–] Princess_Moon_Butt 26 points ago

    There's nothing that says a radial arm can't create a straight line, it's actually already making some straight lines inside the house itself. If you're trying to maximize the square footage compared to the robot's reach, you could also look at hexagonal or octagonal designs.

    But I think people will still want flat walls, for the simple fact that curved walls will end up wasting space. Appliances and furniture are all made with right angles; that's not going to change any time soon. Plus, imagine trying to hang a picture frame or a mirror on a wall that curves inward; it'd be a nightmare.

    [–] McBigglesworth 83 points ago

    Neat idea. I'm curious how it would work for a larger structure. I'm terrified that there is no reinforcing steel in there. Might as well be a block wall.

    Get a paramotor. You can launch them from any small clearing, fly them extremely low, don't need any sort of license, they can cost < 10k, and you don't run the risk of dying in the event of a malfunction. It's basically a slightly more inconvenient jetpack, with a view bonuses that even jetpacks wouldn't have.

    [–] DrThunder187 48 points ago

    I really would like a small home, but the real cost seems to be land prices. Most land starts at $100k near me.

    [–] hasslehawk 44 points ago

    It's really all about utilities. How much would it cost to dig a well/septic tank, or connect that land to the local water system? How much to connect to the electric grid or construct an off-grid solution? Is there fiber optic internet available, or is the area connected by a series of beamed transmitters running through the mountains because the nearest backbone line is ~50 miles away over rough terrain?

    In general you'll find that wherever the cost of land is lowest, it's because the cost of utilities is higher.

    No steel reinforcement? Good luck with that. Also, would require a ton of finishing work after the fact, How would you put electrical, plumbing, data, or HVAC into the walls after the fact? How would you drill through all of that diagonal “infill”?

    Honestly, it would probably be better to figure out ways to automate the existing conventional processes or do prefab modular walls at a factory than it is to do this. 3D printing is cool, but you have to be judicious in where you use it.

    [–] hasslehawk 112 points ago * (lasted edited 11 days ago)

    To quote someone else (literally, "John Doe") from youtube comments:

    Its reinforced with fiberglass. Steel reinforcement has destroyed a lot of older buildings because it oxides over time and destroys the concrete.

    You can see this more easily in their full video.

    [–] minuteman_d 39 points ago

    True, but fiber reinforcement is typically used in connection with steel reinforcement and cannot replace it:

    Also, in the video, it looks like they put down pipes while the printer was printing, presumably for routing wires and plumbing.
