Gradually we come closer to the small flying robot beings from the movie "Batteries Not Included" (those could build and repair everything). The difference between wasps and those drones is that insects also have legs to stabilize their position and possibly even fix flaws in the applied material, so a precise 3D printer drone swarm likely should have additional small arms to be used in a similar way.
Same principle as "When you have a hammer, everything is a nail !". But is it ???
Concrete without rebar... sounds like it should last 2 or 3 years
If this push thru.. a lot of people will lose their job
You claim 3d printing in construction is environmentally safe, efficient, and is a business with alot of money. No more scaffoldings , no more wastage, no more heavy equipment, NO MORE HUMANS. I really don't get it why these people are so amazed in machines replacing humans.. ai, human like robots, drones and now these... Evolution means extinction of the latter
One problem I see with this is that using drones to lift materials requires a lot more energy than using a crane. And once the material is up there, the crane can keep it there with virtually no energy expenditure while the drones need to burn a lot of energy just to stay airborne.
A concentrated solar array at the site would fix that, just make the initial costs slightly bigger. Still not as much as the extra costs from both time and heavy machinery
Probably energy expenditure flying those is not a significant cost all expenses accounted. But the crane system would be simpler, faster and less prone to failures. Drones would be maybe better for hard to reach places and fine details.
@@cython5086 No it doesn't. Cranes are still more energy efficient.
@@cython5086 if we're gonna set up a solar array for the drones then you have to consider doing that for the cranes as well. Either way the cranes would be cheaper and more energy efficient. this is definitely not efficient or enviromentaly more friendly but it does have use cases for MaRs BuIlDiNgS :-/
That would require extra solar panel production which is also energy intensive. But a solution in the long run for sure. But won't help much short term.

LOL

Doesn't Hexagon mean '6 sides'? The bees seem better at the job at present.
@@pcka12 that was exactly the joke part
@@DeathSugar so 'a pentagon'.
Well, those are some rather dramatic predictions. I'll believe it when I see it happening.
You won't because it's dumb.
@@jvon3885 - Not the word I'd have used, but I wouldn't argue against it. KZhead influencers have always loved to make big dramatic predictions about new technologies. They rarely come true.
Idea: adapt one of those sports stadium cable-suspended cameras as a 3D printer. Would remove the flight/battery issue and have similar benefits plus more stability. Like a giant delta 3D printer.
brilliant! i'm all down for that one. huge delts 3D printer have been dome before, and (unlike this bogus) it's a really promising technology.
But drones are cool and trendy.
Already I thought of several ideas that SOMETHING anchored to something else that would supply SOME rigidity to allow the same drone to work and not interfere. LOTS of different ways this could be attempted like the one you say. AND you could have a persistent electric power line compared to small limited batteries. That is a must-have for construction. Just think how many recharge cycles you might run in a day at say 20 min per run, and maintain cases of batteries.
@@mrwayneright Yep, and the lines running power to the unit can also supply feed-stock. Definitely way more real-world potential than a swarm of inefficient flying blender-bombs. Using tethers and/or suspension cabling might at least allow for cranes that aren't so heavy-duty, reducing some of the wastage mentioned.
Yes
That sounds like a good Idea. But I'd be rather pessimistic about that. First: a drone can't carry much filiment. Keeping a heavy load in the air is a energy expensive. And only taking small loads but many refill tripps, doesn't really lower the energy consumption. A crane that can hold a load in the air without further energy-input is cheaper then to have to keep putting in energy to remain in the air. Second: you have to upscale the drone quite a bit for large constructions. However larger drones need sturdier heavier materials further adding to energy consumption. Third: weather conditions. Holding a large drone still enough against wind and weather will be rather difficult. So you can only operate at still weather.
Was thinking the same thing but I thought construction stopped during weather conditions because holding anything against wind is difficult no? Like, I can't imagine swinging steel bars suspended by a crane wire with higher up winds is business as usual
@@bforbiggy chances are the crane can continue to work on higher wind than a drone can.
Yeah drones are just inefficient, even if tethered with a pipe for the concrete it is still inefficient. What they currently have for 3D printing building works much better but if they want to go down the route of collaborative robots then ground based robots are best. Something with either legs or wheels that can go round and build up the walls would be better and wouldn't need stabilisation or to worry about the wind.
@@conorstewart2214 This might sound unintuitive, but OP's 3rd point about wind is actually the easiest one to manage than his other two points - there aren't that many ways we can get around weight and energy consumption after all. Wind, however, is easier. Now, I'm no civil or robotics engineer, but I'd imagine having an independent wind sensor, something you can put around the site, at some distance away, to "forewarn" the drones, would be rather easy. The sensors can then wirelessly communicate with the drones, after which the drones can prepare - adjust their positions, how much to "lean" in a certain direction, and for how long. Like I said, I'm not an expert in these fields, but if even a layman like me can think of something like what I just described, then I'm sure these engineers can figure it out. The weight and power issues are the bigger problems.
Classic KZhead comment... "You're wrong.""
99% of work at height is less risky than driving a car. Minimal chance of some idiot hitting you, redundant safety measures etc.. So not much risking of a life. But interesting technology, I'm surprised how effective it might be.
Bullshit. Falls while working at height are the leading cause of workplace fatalities. Everybody and their mother drive a car to work. More people die in traffic accident? Wow. Mind-blowing. This is not in defense of concrete printing, drones or otherwise. It's a terrible way to construct anything. Printed concrete has simply not been proven to remain stable at any scale, let alone high-rise construction.
Wind: I'm about to end this mans whole career
Carrying material in the air before depositing it on the structure costs a lot more energy than a crane or a giant printer no ?
Yea for large construction projects the cranes would probably be worth the hassle for this reason, but for smaller jobs or emergency applications I could imagine these having their uses
Sure, but more energy for something that's more flexible and 2 or 3 times faster than the gantry style 3d printing, which is already significantly faster than regular building, is worth the efficiency cost. Electricity is cheap and only going to get cheaper.
@@ZirothTech What is a "large" project? For a house-sized project, you could likely design a gantry printer that breaks down in about six major components for transport and can be deployed in less than two hours. Once the gantry is up, it can operate for however long you need it to, no charging or reloading breaks. Though printing speed is ultimately limited by how fast previous layers set hard enough to safely support the next layer.
I could see a combination of the two. A Crane lifts the material close to the use point, then the drones zip about applying it over a short distance. You're still making savings as there is a reduction in labour@@ZirothTech
If the efficiency of the drones and solar cells reaches a certain point, they wouldn't even need to charge, just pick up material and get to work. The efficiency comparison breaks down once we get past energy scarcity.
Somewhere around here I've got a video clip of this guy running alongside a hurdler, filming him. He is holding out in front of him, a chicken wearing a helmet with a small camera on top (the guy, not the runner). The result? Absolutely rock solid footage. Why are we trying to reinvent the wh.. the gimbal when nature has spent millions of years developing the chicken?
Because you don't have to feed, water, and wash a plastic robot. A camera gimbal can't feel pain when the operator drops it, nor does it get anxious when strapped to the side of an aircraft.
i think he's saying they need to be studying chicken necks with ai algos lol......right?
it didn't take God a million years to make a chicken. 🙂
No, it took roughly 800 million years of animal evolution to get us with a modern chicken, with a tiny chunk of that being human guided evolution
wow, as a 3dprinting and engineering "enthusiast" i have to say that is absolutely insane and i would love to experiment with that idea myself, thanks for the great insight mate All thought i don't see large use in them due to more energy consumption as some have stated already... i love the concept and already because of how cool and how much of a challenge it is i am absolutely up for testing it once i am able to 😅
I think it would make more sense for drones to carry pre-fabricated parts that were 3D printed. Thus you make the part large enough for the drone to lift and transport the required distance. I could see that working. Even use the drones to build a structure, using drop in place pre-fabricated parts. However using drones to actually 3D print structures, I think would be too costly. Technically however clearly possible.
May as well use a crane if all you're doing is lifting panels.
In places where cranes can't be cost effectively located, drones might be another option. In the end it comes down to cost and practicality of course.
@@CommentaryTeam1 in places where you can't get cranes you likely aren't building anything large and chances are you can fit a small crane or forklift in rather than drones.
@@conorstewart2214 Is see it more about process automation and where it's heading. In the future once this drone assisted construction concept evolves sufficiently, I have little doubt it could find a niche in rapid modular construction. Something I'm not sure a crane would be well adapted to. It would hinge on the design structure being modular and optimised for construction via drones, using pre-fabricated components, simply lifted into place by drones at a fairly rapid pace. In the end, it could just come down to cost effectiveness. Modular construction would be easier for drones to adapt to. One off designs less so.
Would love to learn more about the systems that would need to be designed to refill these drones as they'll be limited by their payload capacity. In addition, it might be interesting to dive into the orchestration tactics surrounding swapping out batteries or swapping in/out additional drones as ones need to go offline to charge, which I imagine is something that's already prevalent in some factory automation. Also, how the materials might be processed on-site, especially if it involves locally sourced raw materials, could be an interesting to expand upon further. You've peaked my interest! Obviously there's a lot of problems still to solve surrounding a solution like this but it does look promising for specific applications.
piqued your interest. stirred or aroused, not maxed out. it got your attention. common mistake but you use the word correctly. and you make a lot of good points, I agree, these are pretty interesting problems to sort out
fascinating! It has so many applications once they overcome those pesky outside hurdles... regulations and such. 🙂 I only found you recently, but am really enjoying your videos.
I'm pretty sure 3d printing habitats on mars would work better if the drones just traveled on wheels and used jacks to prop themselves in place to use a robotic arm.
The ingenuity helicopter is absolutely impressive, but there will probably never be much atmospheric flight on Mars.
You are overselling the precision; you are comparing to drones when you need to compare to 3D printers. They got a proof of concept and little else.
both aspects should be covered equally
There's a whole neighborhood going up in Texas that is being 3D printed. Call it what you want, it's more than a concept.
a parallel but important discussion is not only the technical way of doing stuff, but the social. so all this makes any sense.. cooperatives and open source software is the thing to promote along side this amazing new technologies
OMG, 2 of my favourite things, now combined ! My mind is blown!
Using foam to construct buildings has been done for decades. Using a stiff Styrofoam-type (closed-cell extruded polystyrene foam) shell covered in moisture barrier, expanding foam is sprayed or flowed into the center like an ice cream sandwich with common siding and drywall for surface treatment. Inflatable molds can be filled with a dense expanding foam to build non-orthogonal structures. Concrete foam has been used to line tunnels and high volume foam can be used to replace a large portion of a thick (up to 8') non-load bearing slab.
Structurally Insulated Panels or SIPs.
@@slozenger9000Pre-fab?
Dude that is really cool!
it just ain't gonna work. lol
Bro I’m sorry but the reason 3d printers are so accurate is bc they are grounded and bolted. Yeah this method could maybe be used in some very specific situations like remote areas, but there is so much that goes into this. Just look the accuracy of the model that they built in a lab, now imagine that with wind and possibly rain
“astonishing speed and precision!” *show what looks like a playdoh creation from a 6 year old*
Would be interesting to do a rough calculation of the number of refill needed based on the mass of concrete or even foam used for an average house and the payload of those drones . I think It would quickly moderate those industry transformation claims haha
I hope to see this being developed by big and strong companies in my country also.
You always find the most fascinating new technologies.
I think what I find weird about it is that it requires you build everything out of a setting material, when if you want "houses [built] with incredible speed" we've been able to do that with prefab housing for a century, and if you want "simple shelters within hours" you can ship a pallet of wood and a nail gun and it wouldn't even need to set.
This will be amazing for exploration. I could just imagine taking them out to dump batteries to get them very far out in remote areas. And you could get shelters all over the place to be able to access places that other words were ever accessible. I'm thinking some tweaks and you could have them in water and caves as well. Pretty cool. And if you could get the drones made cheap enough, I'm sure you could think of some really cool designs. If you're not worried about losing the drone in the process. Maybe the drone becomes part of the structure.
As a carpenter, I'm pretty confident I can't be replaced by a robot any time soon. Maybe in 50 or 100 years it would be possible. If you're building out of cinder block or brick maybe 3D printing would be an alternative. Trying to do precise finish work over that extruded mess would be challenging though.
The genius of this is it let build big prints.
Pretty cool stuff. Would be awesome to see how this gets deployed in the future.
I like how "Ziroth" totally ignore the filament part of the 3d printing process..... It's the small details like that that set apart a real viable project from something designed by ChaptGPT
Very well explained. Sounds like it needs to be proven feasible next at scale.
I was hoping for a detailed review of the delta-gimbal construction. I remember seeing one of the first delta robots 30 years ago. I knew then that there would be future applications. This one is extraordinary.
Can't wait to see where this goes over the next decade.
I recognise the printed structure featured on the video thumbnail. That was a ceramic vase designed by the Belgian artist Unfold and printed on his gantry printer (a modified BFB 3000 if I recall) in about 2010.
I wonder if it makes sense for the drones to be corded, and cement pumped up to them. This would allow for stronger and continuous drones running, and not needing to land to acquire more material. also wouldn't require drones to carry all the material themselves (though maybe that's less of an issue if the drones are corded). Though coordination of the drones through space would become more important to avoid 'crossing streams'.
I.e. steering a swarm of 3D-printing string puppet robots!
@@AerialTheShamen: *flying* 3D-printing string puppet robots!
The drone still needs to lift the weight of the cord or pipe and a pipe filled with concrete is heavy. A robot that crawls or walks along the top of the wall would be better.
@@conorstewart2214 good call
How do you get rigidity into these structures. Are there 3d printing rebar drones. Or..girder drones?
They don't. These drones and most 3D printed houses are nothing but concrete, no metal reinforcement and all electrical or plumbing work needs done after the structure of the house is built. They also likely need to put extra walls up inside or you will have a bumpy, plain concrete wall with all the wiring and plumbing exposed.
I was actually surprised but the trump international hotel in chicago is 1389 ft of concrete, no rebar. but definitely not built with flimsy drones
Awesome!
Wow... I think this an amazing technology. I think it is a bit early to jump to the idea that this will replace cranes since drone carry capacities are low, but for some things where there aren't a lot of viable options except to fly and 3D print on site, yea... this make sense.
this is such a bad idea I didn't even want to finish watching the video but I did
A great thing to try and combine this with is wireless power transmission. It would have a lot of kinks to work out between the lab and the real world of course, but it would increase the size and carry capacity of the drones.
It will be interesting in conjunction with the advances in synthetic spider-silk.
Considering for larger projects, a single pass with a single small drone will have an absolutely tiny impact on the final product. Any errors on that drones part are going to be negligible especially if the swarm is able to detect errors and take action to correct them like a drone with a clogged nozzle or kinematic errors popping off for maintenance etc and another taking its place.
The hammer is still in use because ''the less moving parts, the less issues there can be'' i'm pretty sure this would be a nightmare operation to deal with. The number of failed print possible is huge and we are talking structural integrity.
@@sebtessier5023 Unless you leverage AI to manage the drones, detect and correct issues in real time. You can drive a single nail into the wrong location and still build a perfectly fine house.
@@Neuralatrophy wouldn't it be absolue atrocious tu try an manually control a swarm of hundreds of drone manually? I am pretty sure we would need an AI. Still have to clean hundreds of nuzzle after, find replace batteries frequently, tiny repairs for every thing and that is without mentionning the noise for the Neighbors. I am pretty sure it would get banned in large city
i think that if they would interlock it would create redundancy and make them way most stable. adding an adjustable refill station that could postion itself along the flight path would allow then to refill on route.
I'm more interested in learning more about the printer at 0:43. I had theorized that a printer with an angled head could be interesting, but this is making some *massive* bridging lines look easy. I'm most curious what material it's using, because I don't think concrete works that way.
3D printing is still an emerging and amazing technology. My home printer clearly has 0.05mm or less accuracy when making test pieces. With a 2mm part being too tight, make it just 1.95mm and it fits great! SpaceX and many other rockets use various metal printers now too.
So now the drone just mimicking the hornet building their nest
Now imagine the drones have highly articulate spider/insect legs
do they sting and hunt me down like normal wasps?
that could be arranged
I, for one, definitely want to live in a house that looks like a pile of bird droppings.
the fake door knock had me fucked up
ITT automated assembly, so like premade wall sections and other modular sections, combined with in-situ 3D printing, will be the real game changer.
Yeah, this could definitely be part of a solid toolkit. I wouldn't bank on it as an all-in-one thing for large projects anytime soon. This and small robots for tight electrical work.
Drones probably at least in the States couldn't get any city code approval. They would have to conduct their building experiments out in the countryside first say West Texas, where no such building codes exist. In Europe I would imagine it would even be more difficult. Now I hear there is a 3D house printing company in Austin TX that is a hybrid system using giant Vulcan 3D house printers that does meet code. This because it is also using humans and typical building processes, but it would be interesting to know which codes the 3D house printers are passing what they actually allowed to print. I would guestimate - not much.
Thanks
Would love your thoughts on ocean wave/kinetic energy capture... Exciting field no one's ever really gone after BIG.... Cheers- love your work!
We still need Cranes - Buildings weigh hundreds of tons, lifting all that via Drone will be taking more Time than with a single Crane. Awesome Video.
Factorio becoming real
looks like irl factorio
I think this will prove more useful for aesthetic repairs in hard-to-reach places. I'm not sure the strength or layer adhesion of material deposited like this will meet the regulations required for any kind of load-bearing structural elements.
Yeah this will be better used for other things than building the walls. The walls are built on the ground so why not use ground based robots? Drones may be good for spraying insulation or paint though.
I think printing buildings is unquestionably the most environmentally benign method of building, especially if a proportion of the matirial used comes directly from the construction site. It will become ubiquitous soon enough. Using drones to do this, however will remain a niche option simply by dint of the weight of the materials used. Scaled up, the drones illustating the principle would be helicopters! Brilliant channel...thanks!
Reminds me of the cute robot-aliens of 'Batteries Not Included'. Build, build, build.
I could imagine hundred of these working like bees.
The delivery of construction materials by air using drones or airships is interesting. But it's ridiculous to build without relying on a building.
Love how useful this could be in crisis situations!
This is so dumb that it's double jeopardy: I love it ❤
Hi, The wasps and bees do not build their hives while flying, they use thir legs for stability. What about just mounting necessary structures by drones? Pre-planned small structure parts brought together, and self-mounted by a plan?
This will NOT replace any current technologies used for building the usual stuff. We do it much more efficient than some flying drones. What this CAN be used for is for building stuff we did not even know we could build up until now - some small remote structures that would require way too much effort to haul a big crane up on a mountain or something like that. This is NEW technology for completely NOVEL kind of builds.
everyone gangsta until the wind comes in
Nice!
Hold on- hold on… hear me out… what if… “3D printed drones that 3D print”?
Many problems with drones have aleady been pointed out: precision under wind gust, weight load, fuel efficiency. In addition, drones would be most helpful for high-rise building construction, but the 3D printed materials would likely not have the required tensile strength where steel beams are normally used.
as this tech advances, the drones will probably have smaller extra rotors for stabilizing
Our race is amazing.
Yeah, very efficient, very genius
I can see this stuff happening in less than 10 years easily. I can also see it going far beyond what is predicted here. I don't think skyscrapers will be 3D printed with drones, but with large gantries and other types of cranes, who knows though! Really large tethered drones with constant power might be easy enough to make work, especially if they start using those toroidal propellers that provide more lift and are far less noisy.
Really cool idea. And I have drones and 3D printers and love them both. Problem here it's going to be power to weight ratio. Construction materials are very heavy, drones have limited carrying capacity. Anything that can build buildings or lift girders or eye beams is going to be massive, and cost way more then Caterpillar or a simple crane. We'll have to see where the future takes us. But i don't see drones doing this for a long long time..
Yeah drones aren't suitable for this really. Ground based robots or gantries would work much more efficiently. Maybe even something that crawls along the wall and poops out concrete behind itself would work. Also it is "I beams" not "eye beams", they are named because of their shape, it is the shape of a capital i, similarly they can also be called "H beams" again because of the shape.
And now we can create 4d printing where you add nanotech into the structure so that the building will always be under construction when the nanobots fix any portion that's needed over time, or even programming them to build the house you need over time, with the materials that are present...🤯 progressive nano builds
Some lines of the video made me think "what could go wrong?"... "...when, not if, drone swarms venture outdoors into real life..." "...working on replenishment systems for materials and batteries..." "...autonomous drones 3d-printing a house doesn't seem all that far-fetched..." I'm picturing drone swarms venturing outdoors under the control of autonomous scandrones, occasionally replenishing themselves so they can build... more drones.
this was a really interesting & beautiful vide. - T.Y.V.M. - Thank You Very Much
Imagine these things in space, just with rockets or laser propulsion instead .
Goodness me. Until the batteries run out !
Between this, the eight companies making humanoid robots and the open AI AGI lawsuit that apparently says that Open AI has AGI, the world's getting super weird. I can't be the only one that notices this right??
Part of me wants to keyboard-jockey about all the unsolved problems we have here, or propose my own solutions. But I AM NOT the one programing the drones and doing the research. THEY are. There are other reasonable posts here. So I wish them well and to accomplish actionable solutions before they run out of research money. Thanks for the story, Ziroth.
3-D printed houses only print the walls. The foundation, roof, windows, doors, insulation, wiring, plumbing etc are all still done manually.
Exactly. And putting up the walls and roof of a truss-based metal building can be done quickly by a small crew.
Why not use a tethered drone with a power cable and material feed pipe/tube. The extra weight of these would be offset by not having to carry batteries and product. There would be no refilling and battery swaps, so it could run indefinitely. You could also have an autonomous ground robot/tanker vehicle for larger construction jobs and to minimise cable/tube lengths.
This is awesome!! Worker wasps 🐝
I've seen this in Command & Conquer Generals
You telling me that wind, which is practically everywhere, will not affect the accuracy?
Have two drones stacked ( sort of ) the top drone could hold the material the lower drone printing.
To be really efficient, and to more closely follow nature, the drones need to land, thus not wasting fliying energy, and then deposit a part of the structure before flying off and collecting more material, or moving to another area on the structure. This is the way.
Ah! Nice. I've design ideas to prototype for those large printer heads. Consider the implications of printerdrones in space! Large scale swarms of printerdrones is our future. They will bring about increases in speed, and in scale of manufacturing that is, well, sci-fi sounding now! Swarms making volumes of useable habitable space, in orbit, say of volume of the Twin Towers per week! Then if we want it in a day we scale it up. This means that say a McNiel Cylinder that is 10 miles across and 30 miles long might take a year, the 1st ones we make, as we scale up to that! One that size can take generations to "fill" and would be totally food secure, export to earth & others, focusing on specialties. Keeping things on earth, printerdrone additive construction will be amazing! The implications on design too! Those printer head designs take into account some interesting use cases. Much work to do!
looks like the biggest thing you could print with this is a hamster cage
I don't see flying drones replacing cranes or large 3D printers for construction, but they could be useful for some jobs.
Can't wait to see Thunderf00t's response to this... ;)
Then go to his channel.
He'll say it's an even more stupid idea than the hyper loop.And I would agree.
Gantrys are definitely a more doable method for now, they are definitely more emervu efficient, but this has alot of applications in emergency situations and spafe travel
There is no reason gantries can't be used in emergencies or in space travel too. Drones aren't very efficient. One thing you will likely lack in space travel or in emergencies on Earth is power so you want an efficient solution.
@conorstewart2214 I agree, but the biggest issue with gantrys for emergencies is that you dont know the situation you're going into. In unideal conditions, you're gonna need a huge gantry. For space travel, the energy efficiency of gantrys makes them a more permanent solution, but you want to reduce weight as much as possible when you launch a rocket, so in some situations drones might be a good idea. I could see drones being designed to prepare (or repair) hard to reach infrastructure, like the equipment that produces filament for a gantry, the gantry itself, or the higher points on lander craft. Though on low atmosphere bodies though drones are basically usless, same for overly windy ones.
Wind will be the drawback , should that be overcome , reinforcing becomes a problem , along with cooling from drone props.
You know that saying just because you can, doesn't mean you ahould? This is that statement 100 times over.
they took our jerbs!!!
this will probably be used on mars
How about a crane-hoisted platform with material, and then have hoses running down to supply a fleet of drones? They would have limited maneuverability, but that would outweigh the time & energy spent picking up stuff.
