Congrats Relativity on your successful Terran 1 launch tonight. So cool to have known so much from this video while I was watching the launch with my coworkers.
Terran1 failed and they will not make any more Terran1 rockets and no more 3D printed tanks. TerranR will be another 1 stage only reusable rocket with some 3D printed parts which will be launched somewhen in 2027. So I wouldn't say it is successful.
@@johnvonludd1738 Gotta start somewhere, right?
@johnvonludd1738 Ima introduce the starship argument; Terran 1 was quite successful since its goal is MAXQ because they wanted to prove its structural integrity. Terran R was only skipped to because of the success of 1.
Well.... it worked!!!! I just watched their launch video and it was amazing! To get through Max Q and first stage separation on their first try with a 3d printed rocket is just nuts. I heard about Relativity for the first time here and was really skeptical about it working, but I'm so glad it did.
Looking for such a comment. It wasn’t a 100% success, but at least the part we’re interested in seeing did make it.

@Erina Isshu I'm not against failing, I'm against using wrong ways to do something and trying to convince everyone that it's the best way just to give up on it later and start making things like everyone else.

The old joke. "If the weld is stronger than the metal, then why don't we make the whole thing from weld?" Finally joke becomes reality
Ba-fricking-da-boom... thats funny
That wire and other factors make the total structural stress factors all over the surface on a micro scale that they can't find.
Slag inside not easy to find.
Like the sheet metal press molded auto body .. the stress factors are many and randomly happening on the microscopic surfaces that are hard the find and causes the whole thing to be no good.
@@carlojones8610 so are you saying it's not better to make the whole thing from weld?
@@carlojones8610 you should call them and let them know they are wasting money. SpaceX too. They are 3d printing parts as well. You'll be their hero.
I was thinking the same thing. It now is practical to do it.
I recognized Scott Manley's voice way before his face was on screen. What a LEGEND.
I knew I wasn't the only one.
Same, all those hours of ksp tutorials...
Same, I actually had to check if I opened up another tab for Scott Manley video by mistake when I heard his voice.
how unexpected that scott manley appeared lol
Awe, I need to start playing Kerbal again.
When I first heard of 3d printing, one of my first thoughts was that in the future you could stick a welder on a robot arm and 3d print metal. Really cool to see a way more sophisticated iteration of that idea being used to 3d print a freaking rocket.
And you know what the scary thing is - provided we don't wind up wiping ourselves out or what not: in a hundred years or less - this sort of "revolutionary" technology will be relegated to child's play.
I mean just look at the Internet and computers - they were originally devised for advanced means and yet these days kids can do things with them that the original creators would never have imagined.
The aerodynamics of 3d printed parts are pretty surprising. Some experiments have shown that the texture forms a cushion of air that actually reduces friction.
Like a golf ball..
like a golf ball
Or shark's skin
This is quite the incredible company. I'm particularly impressed with their algorithm enabling them to print warped in order to cool straight.
This is the best comment in the comment section! Super impressed with Ellis and Relativity Space!
Yeah that's a huge deal.
This is standard stuff in metal 3d printing - just here a lot of it is done with an actual welder. The 3D printed parts are also made larger so they can be heat treated and end up with dimensions that frequently are finish machined to proper size.
I know this is pretty insane.
You can also check out resonance filtering in Klipper 3D printer software. It uses resonant frequency models of printhead at high accelerations to cancel ringing, thus enabling faster printing. Oh, and it's free software (free as in speech ;) )
As a hobby welder, this was really interesting. The fact they wrote their own software to compensate for warping so well blows me away.
there must be some hardcore AI engeneers at works there
@@korok2619 this is so freaking obvious, this could applied to fdm, ultra fast antiwarping printing, although I rather print scram jet parts at 4500C instead using classified solid state flame synthesis 3D printing using planetary ball milled nano composite metal-ceramic powder. Mentioned the 3D printing idea to a post doc in 2018, couldn't talk about his DoD research, but my creativity isn't classified and I'm an anarchist IDK what they did but I think my approach has a chance of succeeding .
Seriously, the fact that they modeled thing so well that they intentionally print it "wrong" so that when it warps it will be exactly how they want it is really *really* impressive.
It's actually easier to use ML to control defects than what you feel. I feel very excited thinking about what future holds for us
That was the most impressive to me
The amount of work and people you have long conversations with only to show highlights in the actual video of is truly astonishing man. Thanks for all the time and effort that you put in to each of your videos man
You got urself a new follower Relativity, really like the vibe and the direction you're going with. I believe manufacturing will be "printed" of some kind, master it and show the world how its done. Big thumbs up.
The StarCraft referencing was the icing on the cake...
The whole nerdiness vibe really says something about the passion involved with this company.
didnt expect to see you here
Oh hi moonbo I see you take inspiration from Veritasium for your builds.
It's incredibly nerdy and I love it.
NOT ENOUGH MINERALS
As a qualified welder, the reverse warp simulation is amazing. Given the number of variables in the welding process this is very impressive.
As a welding student - im curious how they avoid problems with oxide layer inconsistencies seeing as its aluminum welding. I guess maybe the printer runs cleaning passes before depositing metal?
As a pressure vessel inspector, I have serious doubts that that tank can handle 50psi of pressure. All it would take is one microscopic flaw in one of the welds would cause catastrophic failure. Welded metal air cooled as it is in this video is way weaker than forged or rolled metal. I would like to see the pressure testresults.
@@JoshGariepy I'm pretty sure the wave form changes are wiping any oxidation.
@@Jerichoswa11 thats true, but i think it has potential for inclusions regardless unless the printer has some sort of precleaning action prior to adding filler
@@JoshGariepy agree, if they did the welding in a controlled chamber filled with a gas maybe. This is just a room at ambient temperature. Molten metal that cools at room temperature inherently cracks, when welding, preheating is used and post heating to align the grains in the welds. My bet there is cracks all through these welds.
Literally on the pad right now, Good luck Relativity.
@9:05 loved hearing about the brazing. It’s not actual welding. The base metals don’t melt. The best steel bicycle frames are brazed. And it was neat to learn they use brazing to move liquid hydrogen.
This video was fantastic. I love how it embraced the philosophical implications. I thought Scott's comments at the end about the future of 3D printing rockets were very interesting. Man, what a great video.
HI DESTIN!
YO DESTIN!
A living legend has arrived
Waiting for something even cooler from you...
Destin's just shaking his head about the lack of Laminar flow over that bumpy rocket.
Don't care what he's building, flying to Jupiter or whatever, the fact that he's worked out the distortion into the weldment has got me sold. Nice job.
Yea I thought that was insane, how can it be a predictable pattern which they can reverse engineer? Who tf would have thought to try that?
@@gnatdagnat Rocket scientists who understand physics at a level so unbelievably high above our heads
In seriousness I think material scientists would hold the crown on that achievement
@@SyrupSplash They are too busy wasting their time trying to figure out how to create materials to fail for forced obsolescence.
yeah. ^^^ this.
Yeah, time to invest for sure.
EDIT: Apparently the private sector is very interested, so there's no immediate plans to go public. :(
I love the idea. I've been watching 3D printing grow to serious industry for a while now, but haven't seen something this ambitious. However, there is something that may need to be considered and that is the standardized testing that is typically performed on equipment like this before it is considered flight/space worthy. Currently, Non-destructive testing (NDT) is performed using many techniques, all of which are designed to look for discontinuities on material surfaces or porosities in welds, etc. When things are 3D printed they are not formed or created in the same manner and so they may or may not have the same types of flaws that are found by modern methods searching for these flaws. I mean to say, it is hard to tell what types of imperfections or flaws we might see as the norm within 3D printing. It could be that the material is better in every way. There just needs to be more testing and research in these larger scale things that 3D printers can create.
I hear you loud and clear. The imperfections within the material are something that has to prove itself. Years ago I did design work for ASME Code VIII pressure vessels. We tested Japanese flanged and dished heads for the radius ends of the vessels. The Japanese steel of the day had a problem with voids that arose when forming those heads. Big failure. But testing had to be done. 2 years later Japanese steel was higher quality than from U.S. Steel Corp.
But the welding process used here is so controlled, my guess is that testing will give great results. Small welds have very much less wattage than heavier welds. I also see this as eliminating 'stress risers', which are serious failure points if they exist.
All metal products start out as molten. That used to be in like Bessemer furnaces. Melting it as it is built is so effing cool. Removing all the machining and forming steps is a quantum leap in manufacturing slash assembly. Removing the individual parts and cutting down on how many - that is absolute genius, whatever company does it.
I am retired now, but if I were 25 or 35, this is a company I would want to work with. The amount of creativity they get to do would have suited me perfectly. limi
3d printing plastic is is now affordable to any one, the Positron v3 is like $90 more precise that almost any non resin 3d printer and it can FOLD the thing can fold into a shape smaller than a laptop adding on to that is is among the fastest plastic 3d printers ever.
Spray it with spot checker and x ray it
I do inspections for the refineries. CWI and various API's stuff like this won't get x-rays. They'll end up doing UT (Ultrasound testing) due to how big it is. With a UT they can see any imperfections in the metal without using dinosaur sized film for X-ray. I'm pretty sure they check PT (Penatration testing) and before doing the UT. Interesting how simple this process is. I'm pretty sure porosity can be mitigated in a room filled with argon gas to keep the filler clean.
@@dethtour I can't imagine the PT process for something this huge, but UT has come so far that it would likely be very easy. The problem I'm seeing now is that they talked about wanting to have this technology on Mars to make equipment there. I know they want to create buildings and structures, which arguably would not need much NDT, but if they are planning on creating anything space worthy while on Mars then there may be issues with that. The only way is if they created facilities large enough like hangars to house the equipment and have atmosphere. UT might be best without atmosphere, but I haven't really ever thought about that before. Regardless, there still is atmosphere on Mars just not much of it. Gotta wonder tho, if the low oxygen and no water environment will be a large enough advantage to the equipment's prolonged use.
love to see great educators teaming up to spread information to the masses

I like what Scott Manley said about their developing 3D metal printing capabilities as a solid contribution and business even if they don't make it as a rocket company. I usually just groan when some glassy eyed kid starts talking about 3D printing - because they never talk about material properties or metallurgy. These guys do. That is very very cool.
100% fake comment.
@@neoneo4221 ?
IMHO they definitely should partner with spacex (not merge), SpaceX will have better rockets in the short term (more advanced on reusability), but the direction they are taking here is better for building the Mars base and the long term scaling up of Earth Mars transit.
@@christophejamoye8394 So they would lose the 3D printing knowledge to SpaceX and noone will further invest in them? I don't know.
@@christophejamoye8394 I doubt they want to seeing as how the two founders each previously worked for a rocket company, Spacex and Blue Origin, and decided that neither was innovating enough so they quit and started their own company.
Every now and then Derek brings something to CZcams that just blows my mind. This is one of those times. There's so many little things here that just blows my mind. For example... I never would have considered what was stronger... traditional builds or 3D printed metal parts. Or that they have software that helps print a warped product so that it "warps" to straight. This is fascinating stuff.
Fasfan, One of the best comments here, imho: 'Course that's only because you agree with me... 😎.
Seriously, I think you understood the video in a way that maybe 80++% of the people here didn't.
I still can't believe it.i thought it was a clickbait
can we talk about the materials team developing better suited alloys for this task..? thats insane alone. the anti-warp algorithm is bananas. as a mech. e. major I am drooling over this.

@Rob Bannstrom sure the idea has been around, but there's a little bit of a difference between a CD case injection molded in one piece and a freaking rocket part made 1mm at a time. Lol

Caveat occurs at 5:00 when he explains that this manufacturing method adds 5 to 10 % mass compared to traditional methods.

So... Just ally M.I.G., then. I've always seen that since my first 3D printer (retired Boilermaker), but quickly realised the massive tech issues that'd be needed to be overcome. Good to see it actually done, & love the close-ups of the process. Great work, guys! 👍
At the end of the video, a crucial question was asked and the totally convincing answer was made. It's really very important to vision about that diverse mentality which may arise between those who will be traveling to space and those who can't afford it. After all we are humans, not the martians.
Thanks to @Veritasium (Sir Derek Muller) for showing again, such an extraordinary and commendable work. 👍🏻👍🏻
At a minimum, a company that can rapidly prototype large, complex, and precision parts is never going to run short of potential clients. As Scott said once you get to the point of mass producing parts the benefits of 3D printing get eaten away by dedicated tooling. But if they focus on the flexibility of 3D printing, they can pivot to fill a niche in basically any manufacturing industry.
Well said! Plus even if you have dedicated factories for mass production you will still need the 3D printing for prototyping improvements.
They can pratically be the company that would handle almost all the prototyping of rockets in the industry. It would be unfeasable for any other company to start this kind of 3D printing factory for their testing from the ground up just for their own needs, especially when there's a company that exists, and is willing to create your machiened pieces with years of experience in the field.
also note that, just like this shell type fuel tank structure he's shown, really weird shaped metal parts are almost impossible automate with normal tools, so even during mass production, some parts will need to be 3d printed.
GOD PLEASE DECREASE GOLD PRICE

Always wondered if it will ever be possible to print stuff with/as metals and rock(minerals?). Great stuff. I like the explanation at the end too, its not about who is a billionare or who is poor, its about enriching what it means to be a human being.

Super cool stuff. Thanks for finding this. I had always thought 3D metal printing was a cool idea way before its time. Now a few years later, its time!
You wont me back as a subscriber after the silly tungsten rod experiment. lol
The thing about (home) 3D printing is that it can be incredibly frustrating if you expect it to be something you can just set up like a paper printer and you get perfect results right out of the gate.
Honestly it can be so incredibly frustrating that I've wanted to throw in the towel. But now I'm printing full body armor for cosplay like Iron Man.
In the end, the concept is roughly the same for how this rocket is 3D printed. Pretty incredible.
Haha yes. I bought a printer about 3-4 months ago but didn't have time to start printing.
I wanted to print some items for my house's ceiling fan plumbing and I thought I'd just upload my GCODE and press PRINT .
Nope. You have to tune the damn thing based on filament and other factors.
I'm learning quickly. I've printed 2 functional items so far and I'm loving it. My goal is to add another printer because waiting for ~10hrs is painful
I've been wanting to get a 3D printer, but now you are scaring me. I do work in an office with a 3D printer and some skilled design engineers though, so maybe I can get some pro tips at work?
add a BL touch I haven't leveled a 3d printer except the initial setup in years.

@@mortenrobinson5421 3D printers are really cool, and I think you should get one. I got the kingroon kp3s, which is relatively cheap. Make sure you learn how it works (basics, nothing too fancy). I usually print small models, and simple things though. Get one once you think your ready, and make sure you join help forums, or ask for help, because you will need it.
"3D printing ain't rocket science."
These guys: Hold my beer
To be fair, the point of science has always been to understand more so we can make life easier. If we have a proof of concept of such a rocket going to space with relatively normal expectations, we could cut the price of space missions in half, if not more. But what to do for all those rocket engineers? Focus more manpower on developing better 3D print systems, perfect the systems that have to go inside the rocket.

The beginning of that industry was dominated by start-ups that couldn't or wouldn't do the quality control needed to produce machines that actually worked as advertised. Lack of government or private lawsuits or arrests encouraged this.
I love that Scott's title is "Internet Rocket Scientist"

Ha ha... I thought that was weird in a funny way
oh no scott is the irs get out before they take your tax money
I'm just happy see there's a Scottish guy named Scott Manley. Sounds like a trope or placeholder name for a Scottish action hero.
The cutaways to Derek when Scott is explaining stuff are quietly hilarious.
That's one way to put it
"Don't 'cross the line'? What in the world does that mean? I didn't even draw a line!"
Didn't you say the same thing on one of his last videos? Or are people just that amused by such a mundane thing?
I'd put it more like: Unnecessary and utterly stupid.

I could definitely see SpaceX acquiring them and keeping the entire team there just with way more resources at their disposable.
I would love to
Sounds good, but also having theme compete for the low orbit market sound's like a good way to boost innovation for both companies.
Except you'd have Elon as a boss.. I'd be the hell out of there if you wanted to work for any sort of decent company..
Competition is good
The founder was actually an intern at SpaceX before he decided to strike out and start Relativity
Today was the day that Relativity finally got their maiden launch. The mission was to gather data at Max-Q. GLHF made its liftoff tonight and performed all throughout Max-Q and stage separation, but the 2nd stage engine didn't stay lit. GGs
It's great to see it all happen a year after I was introduced to this project by this very video.

The implications for 3-D printing tools when we eventually get to Mars is amazing. Very excited for the future.
Better first they buy a 3d cloth print machine able to complete the t-shirt of the poor employee at 4:44
Agree with everyone else, this was an incredible video. The flexibility of this fabrication method has me very excited.

Dude sounds like he's having a fabulous time building rockets
It sounds like a literal child dream come true, especially with his passionate he seems about getting humanity out into space
Flat out, this is the way to go! Toys used to me made by hand and out of wood, then injection molding with plastic and sadly some really toxic metals were also used in injection molding for many uses in our culture. So now here we are in the moment seeing a big part of the future in mass production of space rockets and it is exactly where our technology should be as for our human species in our time line on this beautiful earth. Enjoy the ride while you can!
I was in ag in high school. We learned to weld, I remember him showing us jobs we could get with the skills he taught. One was just remaking gears and giant drill parts. We would slowly add layers remaking the worn out or rusted parts. We where basically 3D printing with pens. Except instead of plastic it was metal.
That reverse warp design blows my mind man!
THAT is sheer genius!
@Jerome Samuel ??? Sheer is spelled correctly in the comment.
It's an engineering joke! Shear stress is one of the things they're fighting with that design.

Thank you for making me smarter ! Love it! And thank you!
I always love seeing Scott talk about rockets he has a way of talking about this stuff that is extremely engrossing
That would be the Scottish accent.

He's also obviously very interested in the topic, and that makes it more interesting to the viewer as well.
I love that this rocket scientist nerd threw on his black jacket, leather pants and flashy belt buckle and just owned it and acted like himself. He rocked it.
Don't forget those boots.
And he based his company culture baseline from a video game. Awesome

Good luck have fun on your first launch Relativity!
Seems like a pretty cool company. I love the idea of pre-stressed materials by taking advantage of warping metal while manufacturing.
Oh *god* you’re right that’s pre-stressed isn’t it? Brilliant accident!
@@ringsystemmusic I wish I was a brilliant accident lol
I'm really curious about how they got that working anyways. It would surely be helpful on regular FDMs, and it'd definitely reduce the incidence of failed prints. Maybe there's some kind of sensor keeping the nozzle a uniform distance from the material?
omg just realized this.. it’s truly perfect
What does that mean?
I absolutely love that everything at this company is named after Starcraft. "YOU MUST CONSTRUCT ADDITIONAL PYLONS"
Isn't pylon a common English word in this field? 🤔
I was about to comment that in all caps, now I guess I don't have to.
@@manojlds the "You must construct additional pylons" is a well known Starcraft phrase. He was clearly referring to Starcraft there. but I think that Like you said, he probably said the phrase because it was called a Pylon in the first place and they have to build a lot of it.
It was SOOOO CRINGE
*We have embraced the glory of battle!*
What excites me about the space shuttles engines is the turbo pumps they produce a lot of thrust also the cryogenic cooling of the flannels and other components
The program that they made is absolutely insane as a concept, I have no idea where I would even start if I had to make that.
Finally Derek/Manley crossover we always wanted.
Unexpected but pleasant surprise
Hullo, I'm Veritasium!
Seriously rooting for these guys. They seem like they are having as much fun as they are innovating space launches. Positive vibes!
If you dont mind them burning up the earths oxygen while crying save the earth lmfao.
@@cjbrenner13 I don't think you understand that rockets almost do nothing towards the environment because of the fuel used. Cars are worse and even planes. The hydrogen fuel is not actually bad.
@@kdog__ it takes more energy to produce hydrogen than other fuel sources. If you have a theory, research it before you comment opinions. Burning anything - in massive quantities depletes O2 - thats just that way it works.
@@cjbrenner13 yet you're here, not in cars video which release about 4.5 metric ton of carbon dioxide
@@cjbrenner13 hey so there's plenty of ways to get all the fuel you need sustainably, just because its not being done now doesnt mean its not possible
!!!!! Woah. Another great video! Had no idea this sort of thing was happening.
The guy giving the tour just seems stoked on everything he’s talking about. Love it! Haha
Tim seemed to handwave away the 5-10% extra weight due to roughness as if it were nothing, but from what I know of rockets (which is admittedly very little), conserving weight is the most important factor when building a rocket. Does the rocket get sanded down before use or are they just eating the extra fuel cost as a necessary consequence of using 3D printing tech?
Underrated comment here
even if it is 10%, youd need 10 launches to lose a full other launch on cost, so it is not much, besides its a prototype, sanding it is not the way to go as you could oversand it and make it too weak, i think they seek to improve the 3d printing method to make it less rough, tackle the main thing, not the consequence, also if the whole rocket warps just a hair thickness distance from tip to bottom, thats already a win.
@@felipeaugusto6991 well if they have the machine and file that they used to make the parts, then it seems really possible to have an attachment of sorts to the arm be a sander after the printing is complete. I don't know anything about robotics so, its very possible I'm dumb and so is this idea.
@@felipeaugusto6991 sanding can also be done automatically
Have to keep in mind that this is the bleeding edge of the technology. I have no doubt that if this becomes a viable solution that 10% will get engineered out just from commercial pressure.
Jeez, can't believe they can simulate the warping well enough to print it wobbly and have it cool perfectly straight
Must have some crazy math behind it.
@@TrollProductionsMC yeah but for these people it's not whether it's possible or not; it's more along how much time you are willing to spend (or can afford) to develop the algorithm
It probably isnt true.
Let's evaluate their claims after they have achieved LEO.
Such kind of videos are amazing
I love how this guy is going with this imagine, smaller rockets to transport a small family and on top of that if we have a moon base we can make it a refueling station so that the trip to mars would be smoother and faster either way great work👍
By far the most impressive bit for me is the reverse warping of the rocket body models. Anyone who's done 3D printing of "large" objects knows how difficult it is to make the result match the model due to warping.
I wonder if they could generalize their software for different materials and scales. A lot of people doing small-scale 3D printing would love to have that kind of ability.
It's proprietary!
This kind of software is becoming standard for laser powder bed fusion (metals and plastics) and it exists for some other methods like the wire feed system shown in the video. Autodesk, Concept Laser, and a number of other companies and university research groups have independently developed this tech.
Yeah, that amazed the hell out of me.
@@MrMctastics and that can change
For sure, metal is even worse than the plastics we're used to bc of the high temperature differentials and high expansion. It’s crazy that one section of the part is hundreds of degrees while another part is a bit over room temperature, you can only imagine the warping.
I love in just this months, there's 3 rocket companies doing a tour of their factory! SpaceX, Rocketlab and then Relativity
Really? Cool! Could you share the links please? :)
