    These guys are going to beat SpaceX to Mars

  2. марина марина on August 21, 2021 at 1:54 pm

    MV rất hay, i like it 😷💜😅

  3. Howard Howe on August 21, 2021 at 1:55 pm

    If the printed engines are as reliable as the hand buit ones and say half the cost. Then Relativity builds the SpaceX modified engines in numbers and Elon pushes the time tabee up as the automation Relativity makes is applied to more and more of SpaceX physical plant.

  4. Daniel M. on August 21, 2021 at 1:55 pm

    This can significantly reduce cost but most importantly decrease production time for the construction of rockets! I hope I live long enough for commercial space travel for the average US citizen.

  5. Wrecked Revival on August 21, 2021 at 1:56 pm

    sooo where do I invest? 👀

  6. Noob Stuffz on August 21, 2021 at 1:58 pm

    I deadass got an ad to go to space

  7. Виктор Фирсов on August 21, 2021 at 1:59 pm

    Fly safe!

  8. Putikl on August 21, 2021 at 1:59 pm

    5:26 OK i need that software. Everyone with 3D printer knows warping is a bitch!

  9. stillwater builders on August 21, 2021 at 2:02 pm

    Wow, one day they’ll be able to print the entire structure functioning, from the printer. A multi-head all material printer. Sooner than I thought, very impressive.

  10. D. S on August 21, 2021 at 2:04 pm

    In spanish???

  11. IDIOT SANDWICH! on August 21, 2021 at 2:05 pm

    This is truly an inspiring video. From the development of machine production to the future of 3d printing as well. Its just amazing.

  12. Jason HW on August 21, 2021 at 2:05 pm

    They need to package a 3d printer on a 3d printed rocket and send it to planets we plan on exploring.

  13. Angel Luis Espada on August 21, 2021 at 2:10 pm

    FIRMAMENT 😁 there isn’t any "space". The earth is a flat plane surrounded by an ice wall. The world is a stage 😆

  14. bofooit gojo on August 21, 2021 at 2:10 pm

    I love how excited this guy was to show off everything. The enthusiasm is contagious

  15. Hazy Skies on August 21, 2021 at 2:11 pm

    Despite knowing this is a scientific video, I still get briefly confused at the channel name thanks to Harry Potter. Me briefly thinking it says "Veritaserum" instead of "Veritasium".

  16. Jake Witmer on August 21, 2021 at 2:12 pm

    This is the most amazing thing I’ve seen in a long time. Excellent stuff.

  17. Ameen Ibrahim Raffic on August 21, 2021 at 2:12 pm

    Today I clicked on the link after seeing the title "Genius of 3d printed rocket " though it has been popping out with some other title for few days now ! Clickbait / Legitbait theory confirmed 😂

  18. Bryan Knecht on August 21, 2021 at 2:12 pm

    thats no printer ist just weelding

  19. barry fraser on August 21, 2021 at 2:14 pm

    For rockets I would think even a 10% increase in weight would be a big deal.

  20. Munchprime on August 21, 2021 at 2:15 pm

    Dude, this company is so cool! There is so much potential here. I really hope that they succeed.

  21. Jamie Lennox on August 21, 2021 at 2:16 pm

    I love this guy!!

  22. zay k on August 21, 2021 at 2:18 pm

    There are many things that don’t make sense to print. It sounds like they want to print everything for the sake of being able to say they printed everything.

  23. Howard Howe on August 21, 2021 at 2:21 pm

    Elon and this guy need to have a meeting. Goal of meeting is to get printed engines. Cur SpaceX price point even lower and maybe get more rockets flying faster.

  24. Michael Qi on August 21, 2021 at 2:22 pm

    is this better than using forged aluminum ?

  25. Beemer WT on August 21, 2021 at 2:22 pm

    That is brilliant.

  26. David Avendaño on August 21, 2021 at 2:22 pm

    Wooo, this is really "Other level"… but… what do they do when the printer runs out of magenta? (but, it’s aluminum !!!, the printer still says "no magenta")

  27. Willem Ringer on August 21, 2021 at 2:25 pm

    Give me the turbo that’s on the rocket

  28. Evan H on August 21, 2021 at 2:25 pm

    Oh, I get it, the genius is the dude.

  29. ltj1024 on August 21, 2021 at 2:26 pm

    14:41 Every StarCraft player would get his "constructing additional pylon" joke right here. Haha!

  30. SB on August 21, 2021 at 2:27 pm

    That’s a CEO who knows his stuff!

  31. Boomatic on August 21, 2021 at 2:27 pm

    haha love the starcraft references. when are you gonna star work on broodlords and mutalisks?

  32. Edwin Vigil on August 21, 2021 at 2:29 pm

    Anyone remember those anti music/video piracy ads? One of the lines was ‘You wouldn’t download a car, would you?’ Can we 3d print a Shelby or sum?

  33. IDIOT SANDWICH! on August 21, 2021 at 2:29 pm

    damn, this reminded me of dr stone byakuya reboot manga where the whole satellite was 3d printed.

  34. Bekæmp Ondskaben Fight The Evil on August 21, 2021 at 2:29 pm

    Have you been 80 kilometers up you self? Have you any pics/Film taken from it?? We all/I like 2 see them..!

  35. zay k on August 21, 2021 at 2:30 pm

    5-10% increased weight is massive for a rocket

  36. Vile Basilisk on August 21, 2021 at 2:31 pm

    (techy sound effect)

  37. Daniel Goddard on August 21, 2021 at 2:33 pm

    10:15 This is a BIG claim that some multi-billion dollar engineering firms have learned the hard way is NOT necessarily true! I’m an aerospace engineer and looking at the surface of that rocket makes me cringe… hard. 3D printing is an alluring process, but there is a reason that successful applications have been limited to SMALL parts, not *entire* rockets. The issue is the mechanical design limits you can work with have wild variance and you need EXTENSIVE testing with each alloy and process to get your hands around it. Getting a reliable S-N curve, Goodman limit, or even just dumb isotropic yield strength is tremendously difficult with this production method. You can try and recover strength by post-treating the surfaces (e.g. post-machining, HIP [lol, for a whole fuel tank?!], peening, or other heat treatments) but the fatigue allowables are still lousy because of all the inevitable inclusions. Else, you just have to rely on wicked good process control while designing to limit peak stress and cyclic loading. Good luck with that in a full-up rocket.

    Also, materials science and materials engineering are NOT the same things. Just because you can produce an alloy that performs well as a coupon doesn’t mean that those properties will hold ubiquitously on a macro scale. I just hope these fellow StarCraft aficionados have accounted for this or the stresses are distributed enough thanks to the unibody design that this thing can survive til MECO before turning into confetti!

  38. Dark Delta on August 21, 2021 at 2:33 pm

    Is there going to a scale model launch? I just saw the future of manufacturing.!

  39. Black Panther on August 21, 2021 at 2:34 pm

    Why make a rocket when it can’t leave the atmosphere? I don’t see the point…

  40. JC on August 21, 2021 at 2:35 pm

    Fantastic video
    Also YouTube dropped my Veritasium subscription, grrrr

  41. Syncringe on August 21, 2021 at 2:37 pm

    I heard stargate got excited… Then I heard starcraft…

  42. Coyote27981 on August 21, 2021 at 2:39 pm

    Its interesting to see another modern space company going at it different into the production process.

    And its different than Spacex too, so double the chances to succeed for humanity.

    Its a bit sad how they really go hard out of their way to dismiss what Spacex already achieved. He says this rockets will lower cost 5-10 times to what we got today… maybe compared to old rocket companies, but no way he is putting that thing into orbit for 5x less that a reused falcon 9. So ignoring the fact that there is already a company today making it cheaper, is a bit sad and unnecesary.

    Their achievements on manufacturing and design can stand on their own without dismissing the competition.

  43. Derek Ash on August 21, 2021 at 2:40 pm

    I wish this company would launch their IPO.

  44. Damian B on August 21, 2021 at 2:40 pm

    We’ve lived for generations on earth and still can’t get it right with so much Wars and poverty. What makes you think it’ll be different on Mars?

  45. Bruh on August 21, 2021 at 2:41 pm

    Lmao seizure warning

  46. Number White on August 21, 2021 at 2:42 pm

    When welding 2 steel pieces together, the welding is supposed to be stronger than the steel itself, i’m not sure how that applies to this thing.

  47. noisywan on August 21, 2021 at 2:47 pm

    Hail to all StarCraft fans!

    Must construct additional pylons. For Aiur!

  50. Angry Irishman on August 21, 2021 at 2:51 pm

    You are looking at the future of all manufacturing. Once rockets to space start costing 10 grand a peice, flying cars and won’t be far behind. This is the beginning to a more efficient future that can solve so many problems. 3d printing is worth investing it now, it’s never going away from here. Welcome to what is the technological revolution and industrial modernization overhaul.
