15:33 Not sure where you got the long fins on the latest starship booster. It currently has no fins at its base. Those fins were removed from the design about six years ago. Only four bulges housing the eight long tanks required to restart the inner thirteenth steerable engines are currently at the exterior of the booster base now.
The wavy bulkhead is machinable, stampable, and/or pressure workable Machinable: get a thick disk, remove material to leave the surface. Lots of waste. Stampable: make a toolsteel die set... first pair puts a small set of bumps and valleys; progressive dies increase and redistribute the metal to final shape and thickness. Working: Using an english wheel of sufficient bar length, one can redistribute the metal from the disk to where it's needed; it's like multi-die stamping, but slower and less expensive to set up, but a lot slower and more error opportunities. English wheel is great for armor making and putting fullers in swords... I've know guys who used them routinely. They aren't fast (neither is hammerworking a set of greaves, but that's slower than using an english wheel), but they're a way of moving metal around a piece without high heat. Tho' one can put a fuller in much faster with a special wheel set for a hot blade... The 3D printing is less wasteful than machining, less setup cost and time than stamping, less time than wheel work. On the other hand, the terran R can be said to be a handful of welds of many miles length... with all the risks welding entails. (I wonder if a friction stir finishing would be beneficial or detrimental...)
Corrugations are a well known method of adding structural stiffness to what would otherwise be a 'panel'. This is exactly where 3D printing shines, it can add corrugations where other processes can't - or much cheaper than other processes, such as press-forming with dies and molds.
Amazing to be able to print such a structure horizontally. Perhaps it prints wider horizontal segments kind of like a tooth, then starts on another tooth and so on, after the 4th or 5th tooth is done, the 1st tooth is already set (semi hardened), then by the time it gets to the 6th or 7th tooth (going clockwise) the 1st tooth is much harder, and the second tooth is set. The big stargate looking printer does not need to move, just the nozzles within it. Anyway... I'm just guessing. Perhaps the printing is going on by hundreds or thousands of nozzles all at the same time. Perhaps the layers being printed are only 1mm thick and thus might be able to stand up to gravity pulling down on the printing. So I guess that is what I'm wondering is how they stop the printing material from slagging due to gravity?
As a retired manufacturing plant manager, I looked over 3D printing and saw great possibilities. However, making fuel tanks seems a suboptimal way to use 3D printing. As far as I understand the process, 3D printing has a series of intractable issues including: the surrounding metal Heat Affected Zone (HEZ) creating reduced flexibility; microstructural changes leading to the metal becoming harder and more brittle; residual stresses into the metal, which can further reduce its flexibility. These stresses result from the differential cooling and contraction of the metal as it solidifies after printing; 3D printing can sometimes have defects such as porosity, inclusions, or incomplete fusion. These defects can create weak points making it less flexible and more prone to failure. The thickness of the printed material can also affect flexibility. Thicker materials tend to be less flexible than thinner ones, and 3D printing often has difficulties maintaining uniform thickness. When compared to rolled metal, 3D printing seems more trouble than it is worth.
These were my concerns as well. A rocket certainly needs to flex, and more than that, needs to flex evenly and consistently across its length. If there are weak and strong areas within the walls, the violent stresses will reveal those areas. I hope the failure to reach orbit wasn’t due to this. And if so, hoping they can figure it out.
@8:12 my theory is that pattern is for strength because it’s a similar story with the Ford train motor. The corrugated body was rest strength. They try to get a Ford tri motor with a smooth body, but it couldn’t pass the FAA due to not being strong enough of a fuselage.
could 3d printing rockets be possible IN space ? like would 3d printing be a more effective way of building bigger ships within space? or is it not possible
In DED (Direct energy deposition) Processes like they use here, the overheating of the part itself is a challenge. To get a good metallurgical microstructure and therefore good mechanical properties, you need to control your meltpool as well as the printed layers. Without convection cooling in space it gets even more complex. However it is possible and the absence of O2 in space enables also printing of reactive metals. Habe worked with electron beam AM machinery where you also work in vacuum. That’s the nearby future.
This is a great channel as Terran is one hell of the name for a rocket. Terran is a typical red wine from Istria (my peninsula) and is guaranteed to take you into orbit every time you open the bottle. Istria is also a V-shaped peninsula like the Relativity logo and resembles a bunch of grapes. And the rocket with methane fuel is not far from a bottle with ethanol. And the Istrian land where the Terran grows is as red as Mars (even more). As I see it, this rocket is a tribute to Dionysius. Those guys got nailed, no matter if it works or blows up
This channel is fast giving a serious chase for quality content to the popular big boys like Everyday Astronaut, Scott Manley etc. NSF , WAI , Marcus House are not Apple to Apple comparison with you. They are news vendors. Good going. Keep up the great work. I am binge watching from down under. ❤🎉 Little more on 3D printing rockets and an equally detailed vid on EVA suits, not the history of how they evolved but more tech content works be awesome.

Same here although the Mars exploration aspect will never be a human thing because too expensive and too dangerous. Mars will become the exclusive domain of AI powered robots. Frankly Relativity makes a better chance of getting one of their spacecraft on the Red Planet than Spacex with their Starship. Starship may look good in a scifi movie but reality has another story to tell.
In the age where 3d printing is so popular and omnipresent it is a good publicity and a catch to attract more viewers. If they want to invest and invent further they have to have views and publicity to THRIVE and progress with their plans. Simple as that. Is it hurtful for the viewer? Depends on the oitcome. No fault in that as long as you enjoy it 😅 fool and be fooled. LIFE.
It's 3D printing, or like somebody else said, more broadly, additive manufacturing. A filament is being fed into an tip where it is heated/melted and stacked on top of other material that was previously heated/melted in an automated fashion is called 3D printing these days. Otherwise, we would call any process like this "3D welding" considering metal isn't the only material that can be welded (plastic for example). TLDR: It's still called 3D printing, not 3D welding.
8:00 the ripples are a way to counteract the expansion, of the materiel wen it is hot. they will smooth out wen the rocket cools from the heat of the welder. The result is properly a smooth tank or outer shell.
Kudos to Relativity Space for their great new technologies and new ideas for rocket production. I fear however that by the time they ramp up, Starship will also be in production and will wipe out all the other players due to the low cost per kg to low earth orbit. There's really no competition for Starship.
This video is misleading. Relativity isn't reusable as they first planned. Their business plan is to make cheap throw away rockets via printing to lower launch cost. It's a good alternative to making it reusable. They also aren't targeting the same market as space x. They plan on doing a lot smaller private launches, their first contract with the new rocket is a privately owned mars rover. That was what the CEO said in a QnA last year anyway. I'm sure the lobbyists are hard at work just like they are for ULA and BO.
@@Bitchslapper316 I agree that Relativity is targeting smaller private launces than SpaceX Falcon rockets, but the cost to launch the same small payload on a Starship is still less than on a Relativity rocket since Starship will be fully and rapidly reusable. Starship will eventually get all the business, large and small.
While comparing the Terran 1 success to Starship's success, you need to also mention that Starship is about to do its fourth TEST flight! It's like Musk saying that Starship 1 didn't blow up the pad, so let's go ahead and get a real payload for Starship 2...
There is a BIG asterisk with what is being said or implied in the video they are NOT going to do full 3d printing or as much as they did with there first rocket. Instead they are going to use "tank straight-section barrels" like traditional way of making rockets.
I can see a future with technology like this in orbit, using resources mined and refined on other planets. Surely their printing hitching a ride on the larger Starship is the way forward?😊
If the Relativity company can successfully 3D print a working reusable rocket, that will be the first innovation of the 21st Century to deserve the title of being "a game changer ". From blueprint to launch stand with virtually no welders or fitters or mechanics or shift workers, needed !! It was not clarified, or I missed it, whether the rocket engine would be 3D printed. I suspect not, because of the internal spinning parts and valves etc.
If a ship travels at a constant 1g acceleration rate it would get to Alpha Centauri in 3.6 years (7.3 years would pass on Earth) and this includes turning the ship around halfway to decelerate. It would achieve about 95% light speed in 1 year. A 10 ton ship would need 10 tons of continuous thrust. This is by far the fastest way we can get to other worlds and the ship would have gravity the whole way. All that is needed for this is a fission rocket that consumes uranium or plutonium only. They are both jittery atoms that are on the verge of fissioning all by themselves. There should be a way to get them to fission in a linear fashion. What's needed is a controlled, time released nuclear explosion. 1kg of uranium contains the same energy as 120,000 tons of coal and plutonium contains even more energy, not much would be needed so the mass of the ship will not change significantly during the trip. In an atomic bomb fission occurs when neutrons hit uranium or plutonium nuclei. This is because they will not tolerate an increase in mass. Due to the equivalence of mass and energy, the same should be true if you infuse them with energy. This might be as simple as having negatively charged uranium or plutonium atoms coming into contact with positively charged uranium or plutonium atoms. Or perhaps with laser or electromagnetic forces. A true fission rocket should not be more complicated than a chemical rocket. With the constant acceleration/deceleration method a ship can span the entire diameter of our galaxy in 24 ship/113,000 Earth years. Systems with stars similar to our sun can be reached in under 10 ship years.
I would like to see a scaled down experiment of this additive manufacturing process done in Earth orbit utilizing vacuum of space and CNC robotics. Space vacuum would make electron beam wire fed additive 3D manufacturing process an interesting industrial technique for producing spacecraft in orbit.
Relativity just does FFF/FDM printing the advantage is all you need is wire and no large foundry system for making sheet so when trying to make stuff in space or on Mars you just need to make wire then print ship part, on Earth we have large foundries that make sheet so it's not necessarily a massive benefit.
17:06 If relativity has developed a method to 3D metal print sideways that is indeed a breakthrough because based on what I have been told in the past that is not possible. The reason is that the metal comes out of the print head in a viscous state. You need to lay it on material below it otherwise gravity will pull it down before it solidifies. I am not an expert on this however. I know just a little more than the guy on the street.
@@jantjarks7946 I am open to new ideas as long as you can reasonably explain how it is accomplished. If you cannot and accept everything that everyone says then you are the one with a closed mind.
그동안은 어떤물건이든 철이나 티타늄이나 스테인리스나 어떤식으로든 물건을 생산할려면 틀이 있어야해. 틀이 있어야 나사나 볼트나 너트나 만들수있지. 틀이 없으면 제작이 불가능했어. 뭘 하나 만들려도, 정교한 틀이 있어야해. 정확하고 크기 모양 완벽한 틀에다가 쇳물을 부어서 만들어냈는데, 이제는 틀이 없어도 생산해낼수있다. 그러면, 우주에서 달에서 화성에서 큰 제조공장이 없어도, 우주로켓안에 3D프린터 제작 모듈만있으면 볼트 너트 뭐든 부품 뭐든 생산해낼수있다.
Those secrets that spacex doesn't hold back is off last i remember since how they make their engines(how the alloy is made and casted) is kept secret to them only. Correct me if I'm wrong please.
@kend6693 The hubris and arrogance of your statement is breathtaking. Building a company is difficult enough much less a rocket company. The fact they actually got a 3D printed rocket manufactured and off the ground is an astounding accomplishment. If you had ever run a successful company you would know that.
11:29 I don’t know about that. It may have, in fact, faltered during max Q, but the damage wasn’t seen until 2nd stage ignition. It seems to me, although someone with a better understanding of engineering might know better…Doesn’t the top portion of a rocket shake more violently due to less mass and the “whip” effect? I’m sure their data told them exactly what faltered and when. Just my thoughts.
and by 2024 3d-printing rockets is not available for amateur groups, student groups etc. Just to give some names --- Copenhagen Suborbital, Astra Bremen, etc. many still can't afford to 3d print metal and that has an impact on engine design etc. Usually what you hear is that more than one engine per stage is horrible complicated together with turbopump design
I agree that we will eventually have outposts on Mars. I don’t however believe that mars will ever be self-sustaining. Too many planetary scale issues to overcome.
There was an experiment called "Biosphere 2" back in 1991 in AZ, 8 people were totally sealed in their own biosphere for about a year. They "pulled the plug" (opened the door?) Early. But I they they had the right idea. It just needed work.
I remember going back to the weeks leading up to NASA landing of Spirit and Opportunity in science class some of thing we went over were long term planes NASA had with space exploration that both Rover fit into. One of the things was printing component directly from more raw material as building your supplies and return rocket on sight would make large scale mission much cheaper and thus easier. And this was the most Science fiction thing i had ever head as again Spirit and Opportunity were still weeks away from their landing.
"Infinitely more freedom to shape the rocket in just about any way" yet they still create a cylinder. So they multiplied the cost & time to produce the same product, what is NASA seeing that I don't. Honest question.
So how long does it take to 3D-print a Terran R? I think this is an important data point to determine if this method is superior to SpaceX's construction method of welding sheets of steel together.
It's not just about how long it takes. It too is about what type of advantages can be realized. Starship has just simple walls, which need struts in areas with large load pressures. In a 3D design this can be built in, or better said, printed in right away. Without the issues that two separate parts which have to be put together usually have. Furthermore, even if it would take longer to build, well, print. That doesn't mean it would be more expensive. Automation can drastically reduce expenses. And it too can mean that 3D printing can lead to higher build quality, at least in the long term. There are a lot of factors to be considered. We will see what Relativity can deliver in the end.
It’s so sad we’re still excited about rockets… We literally have anti-gravity propulsion technology from the aliens…. And have had it for almost 90 years.
If space tech and abilities are true…Venus if it’s atmosphere is mostly what it seems…Venus would be easier on so many levels. 1 the vehicle becoming difficult isn’t as resource demanding because the travel vehicle(s) can require little to be habitable in the Venus atmosphere. It seems lots of harvesting of gas would provide lots….probably fuel..water etc…water that possibly would require less resources than mars for equal amount of water. Sun and temperature resources are way more usable easier and less resources than equivalents on Mars… Supposedly it takes less energy to go to Venus than mars…faster and much more saving resources over time…etc The Idea of Venus first is so smart after the moon….course I mean if we aren’t at those places etc
I am sure that Musk has looked into 3D printing manufacturing Relatively could be that other aerospace company of the near future. The industry needs fresh and creative companies.
True. Hope they don't start doing the same misleading video titles others covering space development have done. I like most of what is done but details matter.
Your video is truly amazing, just like your channel overall. Congratulations on the excellent work! I've just sent an email; I hope you can take a look. Talk to you soon, Laura
NASA seems to buy the idea of a British East Indies Company Over Ming China, or Portuguese and Spanish state financed model. SpaceX $18 million a launch model is VERY ATTRACTIVE compared to NASA's bunch of EXPENSIVE CONTRACTORS. 😂❤
I understand the business decision, but I was very disappointed when they scaled back their ambitions on the Terran R. Hopefully they'll eventually be able to go after full reusability, their high-tech baby Starship
If they are competitive it will be very expensive for SpaceX to do so. And buying out a company doesn't remove the talent to do it again from the world.
Why would they buy them out?? 😂 They’re #1 in the world . Those companies are literally zero threat. They already have the most flown most reliable rocket in the world.😂
@@ivantalavera4748 They would be buying the tech. if they had smaller 100% reusable rockets, that would help them a lot. They could alos 3d print starships in the future, which would help costs go down, and build more. This was just an idea thought
Methane is 75% carbon, that's not "primarily hydrogen with just a little bit of carbon." Most of the exhaust is going to be carbon dioxide, and not water vapor
A 3D printed rocket that is ready for flight at the end is BS, they are trying to print cylinders that can handle it. If you believe that they are printing functioning rockets you need a bit more time on research.cheers.

I am not an expert on this however. I know just a little more than the guy on the street.
What is impossible is a mind so closed, that things for its mindset become impossible to think.
😐😉
@@jantjarks7946 I am open to new ideas as long as you can reasonably explain how it is accomplished. If you cannot and accept everything that everyone says then you are the one with a closed mind.
Then my mind is as closed as the minds of those people who invented all the possibilities we take for granted these days.
😉
@@Oldman5261ain’t there footage of them literally doing it? Ain’t that proof enough that it isn’t impossible?
그동안은 어떤물건이든 철이나 티타늄이나 스테인리스나 어떤식으로든 물건을 생산할려면 틀이 있어야해. 틀이 있어야 나사나 볼트나 너트나 만들수있지. 틀이 없으면 제작이 불가능했어. 뭘 하나 만들려도, 정교한 틀이 있어야해. 정확하고 크기 모양 완벽한 틀에다가 쇳물을 부어서 만들어냈는데, 이제는 틀이 없어도 생산해낼수있다. 그러면, 우주에서 달에서 화성에서 큰 제조공장이 없어도, 우주로켓안에 3D프린터 제작 모듈만있으면 볼트 너트 뭐든 부품 뭐든 생산해낼수있다.
Punto clave, bien visto
Elon Musk enters the chat...."WE WANT SOME OF THESE MACHINES AT SPACE X"
These 3D printers should be in LEO asap for real big steps of progress.
Those secrets that spacex doesn't hold back is off last i remember since how they make their engines(how the alloy is made and casted) is kept secret to them only. Correct me if I'm wrong please.
A good book on how to frugally colonize our solar system is Second Exodus Colony. Located at the Internet Archives.
@kend6693 The hubris and arrogance of your statement is breathtaking. Building a company is difficult enough much less a rocket company. The fact they actually got a 3D printed rocket manufactured and off the ground is an astounding accomplishment. If you had ever run a successful company you would know that.
11:29 I don’t know about that. It may have, in fact, faltered during max Q, but the damage wasn’t seen until 2nd stage ignition. It seems to me, although someone with a better understanding of engineering might know better…Doesn’t the top portion of a rocket shake more violently due to less mass and the “whip” effect? I’m sure their data told them exactly what faltered and when. Just my thoughts.
How exactly can you get a discount on an investment that's completely ridiculous
Relativity's first flight was way much successful than Spacex's.
This is similar to ceramic pot design on a turn table.
I wonder if gigapress tech could have value in making engines and maybe even entire launch vehicles. Maybe that could make multiple rockets per hour.
The Starship booster design presented is an old design.
Relativity should take NASA's resources and ignore their leadership.
We lost a mini starship and won a 3d printed falcon 9
and by 2024 3d-printing rockets is not available for amateur groups, student groups etc. Just to give some names --- Copenhagen Suborbital, Astra Bremen, etc. many still can't afford to 3d print metal and that has an impact on engine design etc. Usually what you hear is that more than one engine per stage is horrible complicated together with turbopump design
ULA has its own launch pads…..
Spacex was the first to 3D print there rocket's
No need to service for the rocket engine BUT isn't SpaceX super heavy methane fueled too ? 😂
I agree that we will eventually have outposts on Mars. I don’t however believe that mars will ever be self-sustaining. Too many planetary scale issues to overcome.
There was an experiment called "Biosphere 2" back in 1991 in AZ, 8 people were totally sealed in their own biosphere for about a year. They "pulled the plug" (opened the door?) Early. But I they they had the right idea. It just needed work.
The Starship Super Heavy Booster does not have triangular fins, long strakes, yes, but no fins.

I remember going back to the weeks leading up to NASA landing of Spirit and Opportunity in science class some of thing we went over were long term planes NASA had with space exploration that both Rover fit into. One of the things was printing component directly from more raw material as building your supplies and return rocket on sight would make large scale mission much cheaper and thus easier. And this was the most Science fiction thing i had ever head as again Spirit and Opportunity were still weeks away from their landing.
2:17 Mars and Earth being separate identities…i am reading red mars, make sense
"Infinitely more freedom to shape the rocket in just about any way" yet they still create a cylinder. So they multiplied the cost & time to produce the same product, what is NASA seeing that I don't. Honest question.
What Relativity obtains approval for 100 launches per year but FAA dragging their feetfor Spacex approval? Something not right here !!!
So how long does it take to 3D-print a Terran R? I think this is an important data point to determine if this method is superior to SpaceX's construction method of welding sheets of steel together.
It's not just about how long it takes. It too is about what type of advantages can be realized.
Starship has just simple walls, which need struts in areas with large load pressures. In a 3D design this can be built in, or better said, printed in right away. Without the issues that two separate parts which have to be put together usually have.
Furthermore, even if it would take longer to build, well, print. That doesn't mean it would be more expensive. Automation can drastically reduce expenses.
And it too can mean that 3D printing can lead to higher build quality, at least in the long term.
There are a lot of factors to be considered. We will see what Relativity can deliver in the end.
You can always add more printers
(They will beat Space X, NASA knows, while space x blows a heavy load this compay is in the correct direction. )
12:26 it was landspace
Is 3d printing the be all and end all or is it not. Seems like Spaceex may have a competitor, maybe not.
Look if a logo needs explaining, it will get wows and aws in the boardroom among the executives, anyone else won't know shit.
New companies should not rush.
Terran was only a partial success. It never made it to orbit. Perfect your first before you rush into a second one.
3D printing may be a way to go.
It’s so sad we’re still excited about rockets…
We literally have anti-gravity propulsion technology from the aliens…. And have had it for almost 90 years.
Space x all the way no1 will keep with them 👍
If space tech and abilities are true…Venus if it’s atmosphere is mostly what it seems…Venus would be easier on so many levels.
1 the vehicle becoming difficult isn’t as resource demanding because the travel vehicle(s) can require little to be habitable in the Venus atmosphere.
It seems lots of harvesting of gas would provide lots….probably fuel..water etc…water that possibly would require less resources than mars for equal amount of water.
Sun and temperature resources are way more usable easier and less resources than equivalents on Mars…
Supposedly it takes less energy to go to Venus than mars…faster and much more saving resources over time…etc
The Idea of Venus first is so smart after the moon….course I mean if we aren’t at those places etc
You keep on saying Terran R is a... Terran R at this point in time is concept/prototype. You can't say something is until it is that.
eh nasa using additive manufacturing to fabricate rockets doesn't even exist so this video (based on the title) is entirely made up lol
I am sure that Musk has looked into 3D printing manufacturing
Relatively could be that other aerospace company of the near future. The industry needs fresh and creative companies.
The image used for Super Heavy (StarShip Booster) does not seem to be accurate.
well neither is the title of the video
True. Hope they don't start doing the same misleading video titles others covering space development have done. I like most of what is done but details matter.
5:34 protoss?
Your video is truly amazing, just like your channel overall. Congratulations on the excellent work! I've just sent an email; I hope you can take a look. Talk to you soon, Laura
Has Elon Musk considered 3d printing his rockets?
Can a 3D printer, print a 3D printer
Uhh ok
Cant the same be achieved by casting ?
NASA seems to buy the idea of a British East Indies Company
Over Ming China, or Portuguese and Spanish state financed model.
SpaceX $18 million a launch model is VERY ATTRACTIVE compared to NASA's bunch of EXPENSIVE CONTRACTORS.
😂❤
I understand the business decision, but I was very disappointed when they scaled back their ambitions on the Terran R. Hopefully they'll eventually be able to go after full reusability, their high-tech baby Starship
Mars colonization is a long way off
Hey great videos...how about one on how the tesla bot will impact the mars mission
SpaceX might buy out their competiors like Stoke and Relativity space. It is similar to what they did for the parachte company.
If they are competitive it will be very expensive for SpaceX to do so.
And buying out a company doesn't remove the talent to do it again from the world.
What you are really buying is the tech and know-how.
@@t.josephnkansah-mahaney7961 Thats what I was tryna say :)
Why would they buy them out?? 😂 They’re #1 in the world . Those companies are literally zero threat. They already have the most flown most reliable rocket in the world.😂
@@ivantalavera4748 They would be buying the tech. if they had smaller 100% reusable rockets, that would help them a lot. They could alos 3d print starships in the future, which would help costs go down, and build more. This was just an idea thought
the simp in this one is strong
Mars was 3D printed a couple of years ago by the LEGO corporation.
5 seconds in and you are already wrong…
Methane is 75% carbon, that's not "primarily hydrogen with just a little bit of carbon." Most of the exhaust is going to be carbon dioxide, and not water vapor
Most things are never %100 3d printed
Get your facts straight.
A 3D printed rocket that is ready for flight at the end is BS, they are trying to print cylinders that can handle it. If you believe that they are printing functioning rockets you need a bit more time on research.cheers.
this channel must also believe in NASA's Starship
Yes, very fishy Bill Gatesesque rags to riches story here. If I were a US tax payer I would be watching Ellis like a hawk.
Time will tell. I have little confidence in this one.
I thought relativity was really kool, until you said Mark Cuban👎
