Did I miss something? Since when does the spacex booster have fins? Are you high?
12:19 wrong information: Zhuque-2 is the first methane-fueled rocket to reach orbit.
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.
yeah that's the old design
The current spaceX starships are all the last of the V1. The new ones are being made in the new starbase buildings.
@@NeonVisualthe v1 didn’t have em
Relativity it's not part of NASA 😅
i was looking for this comment 😂
What??? It's all the relatives working together that drains NASA budget, FAA is kin too....
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.
Good comment. Thanks for sharing
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...)
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?
The aluminium comes from the robot welding it, it’s hard as soon as it’s set
It’s metal not a resin what are you smoking
@@616CC 😂😂😂
This was a great episode!!!! Loved looking at the new rocket and the preview for a next episode! Can't wait for the next
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
Please do another video soon about Relativity’s plans for 3D printing on Mars!
Misleading title. Relativity space is a Private company.
Totally agree about the success! Really amazing seeing next steps and new competition in the industry.
@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.
I’m so stoked about this 3D Printing of rockets.
Awesome video. Thank you.
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 is how science is moving forward with leaps and bounds to 3d printing and have open source will reallly bring them to to the cutting edge
Wow! Hope they can make it a reality
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.
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.
Thanks!
Triangular fins on the bottom of starship boosters?? Cannot wait to see Terran r launch!!
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.
@TheSpaceRaceYT No existing or planned starship booster has fins like the ones that you showed.
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?😊
Kevin: Great statement at 13:15 into the video!
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.
Amazing that these companies have billions in contracts and private bases at NASA in Florida but haven't even reached orbit yet.
I have hopes for relativity because they are taking a new unique approach and pushing the envelope like space x.
It blows my mind whenever I think about the fact that Blue Origin started before SpaceX.
The Starship booster design presented is an old design.
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.
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.
5:34 protoss?
Starship hasn't had those tail fins since about 4 years now...
They need to stop calling them “3D Printed”. They are in fact 3D welded!
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.
The correct term is additive manufacturing.
Metal is a form of filament. It’s both welded and printed.
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.
A hamburger is still a type of sandwich
This is similar to ceramic pot design on a turn table.
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 wonder if gigapress tech could have value in making engines and maybe even entire launch vehicles. Maybe that could make multiple rockets per hour.
12:19 Wrong information: Zhuque-2 is the first methane-fueled rocket to reach orbit
This is definitely a company I want to invest in but how?
NASA isn't available for public investment
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.
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?
I can weld aluminum vertical, horizontal or even overhead if need be. It comes from a spool of aluminum wire on a gun, through the head and gets deposited in a molten form. I see no difference to this "printer".
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.
12:26 it was landspace
The Starship Super Heavy Booster does not have triangular fins, long strakes, yes, but no fins.
You guys need to stop putting nasa in the title of anything space related and start crediting the actual companies that build these rockets
this guy here isn't a fan of NASA's Starship production
Why hasnt musk been building some falcons with the r2 motor
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
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.
ULA has its own launch pads…..
@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.
Hey great videos...how about one on how the tesla bot will impact the mars mission
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
These 3D printers should be in LEO asap for real big steps of progress.
Elon Musk enters the chat...."WE WANT SOME OF THESE MACHINES AT SPACE X"
How expensive tho welds can be strong but costly if the type of materials are special
A good book on how to frugally colonize our solar system is Second Exodus Colony. Located at the Internet Archives.
2:17 Mars and Earth being separate identities…i am reading red mars, make sense
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
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
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.
"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.
How exactly can you get a discount on an investment that's completely ridiculous

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.

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.
Space x all the way no1 will keep with them 👍
Can a 3D printer, print a 3D printer
Uhh ok
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
We lost a mini starship and won a 3d printed falcon 9
What Relativity obtains approval for 100 launches per year but FAA dragging their feetfor Spacex approval? Something not right here !!!
Cant the same be achieved by casting ?

Robot welding is hardly 3D printing.
It’s literally the same process as normal 3D printing but with metal instead of plastic.
If you weld existing metal parts together, then it's not 3d printing, yes.
But when you produce the whole object in that way, then it certainly is.
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
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.

@@oberonpanopticonAbsolutely it is going to be hard, and in space the only participation trophy is a tombstone.
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
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.
Get your facts straight.
Mars was 3D printed a couple of years ago by the LEGO corporation.
It’s so sad we’re still excited about rockets…

I thought relativity was really kool, until you said Mark Cuban👎
Time will tell. I have little confidence in this one.
Misleading, outdated, and sensationalized video. Relativity has already realized that additive is largely a dead end for spaceflight applications, and has scaled back to only 3d printing a few specialized engine components.
Mars will never, never have self sufficient habitation! Mars has 38% the gravity of earth! If a small base were to be established, it would depend on funding from earth! Same as with the moon!
