Startup That Aims To 3D-Print Rockets Says It's Fully Funded For Its First Commercial Missions (theverge.com) 73

Posted by BeauHD from the money-acquired dept.
Aerospace startup Relativity Space -- the company that aims to launch the first fully 3D-printed rocket to orbit -- says it has raised all of the money it needs to launch its first mission and then enter commercial operations as early as 2021. After raising $140 million in its latest funding round, Relativity says its total funding now equals $185 million, which is enough money to carry the company through its first flights over the next couple of years. The Verge reports: Started by former engineers at Blue Origin and SpaceX, Relativity has grand ambitions to create all of its vehicles -- from the engines to the fuselage -- using 3D printing almost exclusively. The goal is to overhaul how rockets have been built for the last 50 years by taking people out of the manufacturing process and automating almost everything. By building rockets this way, Relativity claims it can drastically cut down costs by requiring fewer parts per rocket. Eventually, the company hopes to replicate this 3D-printing process on another world, like Mars, creating a rocket that can take off from the planet and return to Earth.

Right now, the company is focusing on its first rocket, the Terran 1, a small- to medium-sized vehicle being built with Relativity's specialized Stargate 3D printers in Los Angeles. Relativity says these updated printers could eventually create a Terran 1 rocket in less than 60 days from raw material. "Those are actually twice the print size of the prior version, and we have several of those already up and operational," says [Relativity Space CEO Tim Ellis] of the updated printers. Designed to stand about 100 feet tall, the Terran 1 rocket will be able to carry up to 2,755 pounds (1,250 kilograms) of payload, which is just 6 percent of the capacity of SpaceX's Falcon 9 rocket. However, the company says it has increased the size of the vehicle's nose cone, or payload fairing, making it able to hold twice the volume as originally planned.

    I love 3d printing too, but "Rockets" and "Automating everything" should probly not go together.

    It's only a massive controlled burn of huge amounts of fuel travelling vertically into the most inhospitable environment mankind has found. Lets put the robots in charge of wrapping the miles of control wires in heat resistant kapton tape. In fact, lets put them in charge of the thruster control module too! And the comms links, and the guidance systems.... Who needs quality control, materials scientists, and master machinists when you've algorithms, 3d printing, and machine learning? It's just space right? Right?

          It seemed clear to me. We have made machines to work in far worse environments than space.
          Marianas Trench was a good example. You could add the Venus landers. I don't see how volcanoes are relevant.

          • Because you can name a bunch of places that would technically kill you faster than being in space but that's not really what makes it so inhospitable. In the trench you've got massive pressure and the fact it's under water. In a volcano you've got massive heat and you still can't breath. In space you've got no pressure, no heat plus radiation all over the place and the massive distance from any kind of help and a whole bunch of other dangers.

            • The trench is relevant because it's someplace we've actually gone to and come back from, like space, but unlike the inside of a volcano.

              • Exactly, so it's technically more inhospitable. If we were really so inclined it would be possible to build something to resist that heat and provide a breathable atmosphere for someone to go in and have a look or do whatever. For a little while at least but there's not much payoff so why bother. My point was there are plenty of places on earth that can kill you just as quick if not quicker than space but that doesn't alone make them more (or less) inhospitable.

        I'm not a diver so perhaps its too deep, but isn't it a case of just equalising the pressure within the body in a diving chamber first? Then you could swim outside in the trench with a suitable gas mixture and insulated suit. However the unprotected human body will never survive in zero pressure for any length of time no matter what you do.

        • There are no suitable gas mixtures. 70 bar is the world record (in a pressure chamber), with helium+oxygen. The Mariana trench is right above 1000 bar at the bottom.

        • Saturation diving looks like it reaches depths of around 530 meters. It may go deeper but there aren't any public records about it. That's a psi of 711. At 10,000 meters of depth the pressure is 14,227 psi. The human body certainly can't withstand those pressures and the problem for anthropomorphic suits at those depths is joints locking up due to pressure.

    I imagine that much of this 'everything 3d printed' hype is just the sort of PR exercise you need to get VC money these days. Beyond that it sounds like the team have decent experience and there certainly seems to be a nascent market for small launchers. Spacelab use 3D printing extensively in their design, so I'm sure if there were more easy gains to be made in the use of 3D printing they would have been raving about them already. Also, if this startup really had a 3D printer that offered significant process/output improvements over the current industry leading products, then they wouldn't be a rocket startup, they would be dominating the 3D printing market.

    In the medium term though, I wouldn't invest in these companies. If SpaceX or BO get anywhere near their plans for space based internet, then they will be regularly launching satellites into a range of orbits, and I imagine their piggy back service for small sats would quickly destory the economics of these small launchers (even Peter Beck is concerned).

    • There are some advantages to 3D printing. I’ve seen examples of printed titanium parts that were unbelievably light yet very strong, which seems useful for rockets (these parts were to be tested in various aircraft). The structure and shape of these parts is such that you can’t just cast and/or machine them, only building it in layers works.

      Perhaps there’s a weight or strength advantage to be had by printing the entire rocket.

      • They're not going to literally print the whole thing. Flat sheets will still be formed the old-fashioned way. It would be idiotic to print them because you can't make them as strong as rolling no matter what you do.

        There are design advantages to printing the rest of the rocket. When you cast or machine parts you are limited to what can be achieved through those methods. That does translate into reduced strength AND increased mass. It's also very expensive to machine some metals (e.g. titanium) which makes F

    • It's also light on details when fully 3d printed is all you need to say. I mean, are they planning to just 3d print the individual parts out of whatever materials and then put them together in the same way rockets usually get put together with parts made normally? Are they planning to 3d print the whole thing in situ then just add fuel and launch? Some combination of both I'd imagine but they don't say.

      • One potential advantage of 3d printing is that if you can make a part in one step then you can design things as a single object which is impossible to assemble and much lighter than an assembly because there are no joins, seams or bolts. All that is lost though if your parts are less strong than forged parts.

    We can start 3D printing carbon fiber and nanotubes. I am not seeing 3d plastics cutting the mustard here.

    3d printing has a way to go before it meets the materials specifications required for many tasks where some manner of force is applied, either BY or ON said object. Moving beyond 8km/s through 8 miles of atmosphere clearly qualifies as applied force. Unless this -rocket- 12in tall and is using Xcell 3 stage rockets you buy at a hobby shop, I am not buying it.
