🧵 3-d printed rockets?

Anonymous No. 16124145

Have you heard about the company Relativity Space?
>Founded by two guys with degrees in rocket engineering back in 2015, over 9-years ago
>Have raised $1,335,000,000 in venture capital (so far)
>Zero revenue as of 2024
>Zero successful launches after 1 failed attempt (which took 9-years)
>First launch was over 1-year ago (03/2023)
>No launches scheduled as of 04/2024
>Next rocket will be an entirely new design, and won't debut until 2026
>700+ employees

So what do you think? Is this company going to make it? Or are they just burning through investor cash with very little to show for it?

As of now, 3-d printing has limited benefits for manufacturing.
Building an entire company around the concept of "3-D printed rockets" seems like a meme to fleece unsuspecting investors.
Personally, I'd rather invest in a company that was based on updating the already successful Soviet-era Soyuz Rockets designed by Sergei Korolev.

Their first launch was a failure on two separate fronts.
The first stage engines can be seen destroying themselves prior to stage-separation. The green flames are likely from the burning of components from inside of the rocket engines.
Secondly, after stage-separation, the second-stage failed to ignite, and both rockets crashed back to earth.
Seems like it would've been a good idea to install parachutes on test articles so they could recover more of the craft for analysis.

And the final nail in the coffin (for now), is that the company has cancelled all future launch attempts planned for their first rocket (Terran 1), and are already in the process of designing their next rocket (Terran R).
What's the point of that other than to burn investor cash?
Why would they retire their first rocket after 1 failed attempt? If it was that poorly designed, why would anyone else choose to invest in them?
How do they expect to make the Terran R successful (which is much larger and more complicated) when they can't even design a good rocket from the beginning?

Their first rocket should've been designed to be less expensive per launch for small satellite payloads. Only after that should the company even attempt to build a much larger rocket.

It's possible that this company can be successful with this approach, who knows, but to go from 2015 - 2026 with only one failed launch attempt, that seems rather dire.

They are going to fail because they are too ambitious in initial scope. They should have started with 3-d printed cargo carriers which could fit already existing launch craft. Then they could print a launch craft shell, or maybe even start with a 3-d printed train or ocean vessel. They just needed to be more iterative in scope and learn more about 3-d printed vessels in general before they took the big bite.

If the company went with that approach, I don't think they would've been able to sucker in dumb investors.
Their business also could've had different segments from the beginning, like making specialized rocket components for other clients (ULA, SpaceX, RocketLab, etc.), while also developing their own rocket system. At least that would've helped them to generate revenue.
But based on reality, there's no benefit to outsourcing that type of work unless Relativity Space was that much better at it than their competitors.

Why would someone print a fuel tank? that's the opposite to improving 'manufacturing'.

There isn't a tangible benefit yet.
It's possible that 3-D printing a fuel tank or booster will be better than sheet metal, but highly unlikely from a technical or even cost-savings perspective.

If their first rocket was successful I wouldn't even be making a post about it. But as of now it just seems like a giant cash burn with very little possibility for success. Especially given the competition of ULA, SpaceX, and even Rocketlab.

>So what do you think?
it's obvious tech for in situ stuff, to craft new machinery from asteroid metal and, to a lesser degree, recycle shit in orbit

3D printing might help in minimising variants in multiple parts which need to act exactly the same.
One problem in roggets is gimballing, moving the rocket to fire in different directions, to steer the thing. But suppose you had twelve identical rocket-parts all pointing in the same direction, but in different places. Fire one to shift a bit left, fire another to shift a bit right.
If it works, no need to gimbal the rocket anymore. The directional shifting is done in the subrockets.

Why, so it can get buried in shit?
Go fuck your mother

3-D printing rockets is a meme concept, and this company is going to waste billions of dollars in investor cash on a dumb idea.

Kind of reminds me of an unrelated startup from about 10 years back called Juicero. It was a $400 machine that squeezed premade juice packets into a cup and had an phone app and bluetooth and looked all fancy. It raised $120 million from investors. Then some people reviewing the machine realized they could just squeeze the juice packets into a cup with their hands and it was easier than using the machine. It's like a classic example in business of a totally useless product full of buzzwords and trends and raised a ridiculous amount of money for basically a useless product. Just sounded like Relativity Rockets might be the Juicero of the space industry

There are lots of stories of startups that raised a lot of money with nothing to show for it. SpinLaunch is another one, just like Virgin Galaxtic. Both raised a ton of money and then have nothing to show for it. That’s probably a post for /biz/, which I’ll probably make soon.

As for this company though, I still dont see any benefits (cost or otherwise) to building 3-d printed fuel tanks in addition to the rest of the spacecraft.
Even 3-d printed rocket engines seems like a complete failure since the rocket launch showed puffs of green gas/fire, which means engine components were burning themselves apart.
If 3-d printed engines were better, this company would already be selling them to other customers.
Company is definitely closer to being the next Juicero than it is to being the next SpaceX.
