Jointless Hull

Thoughts on the Army's new Jointless Hull machine?
It's the worlds largest 3d metal printer.

    Is essentially what the Army turned me into. A shell of a man with zero cartilage.

        What an odd thing to say. Not that anon but muscleskeletal issues is by far the most common thing I see at my aid station when I do sick call. You’re clearly a never served

    It's the modern version of the Heavy Press Program!

      imagine how easily civilian printers could be switched to military production in a hypothetical future war

      This. This is about as important in our modern era as those presses were (and still are to this day)

      Ye think of how fast we can prototype drones now.
      Cant wait to see the first print. Wonder if it will be public close enough.

    Creating a thread you know will be bad because you don't give a shit about the topic, on a subject we just had a thread on, for the sole purpose of samegay subtweeting yourself with a bad joke

    ...is actually par for the course on this board, why do I still have the impulse to expect anything else.

    Half the board is just this fricking queer talking to himself, like we can't tell.

    Sorry for the dumb question, I'm a no-tanks: what are the benefits (and draw backs) of a jointless hull?

      "Such a tool will be revolutionary because it allows manufacturers to develop geometries that cannot be built in any other way. Rather than rely on defect-inducing processes for joining multiple assemblies, the Army could use this 3D printer to develop a single underbody with complex geometry that is unattainable through any other production method.
      For example, instead of heavy structures, this tool could provide design freedoms to build a single, large, light-weight mesh— combining features necessary for vehicles to be able to both sustain blasts and drive with agility – unlike today’s Army vehicles that are weighed-down with densely built underbodies."

        Doubt. They are far off from volume production. I don't know how much time a press of that size needs to form a piece, but it's going to be orders of magnitude faster than printing.
        Also "jointless" is kind of a meme, since what you are producing is essentially one gigantic welding joint.
        Incredibly useful for prototyping though.

      Lighter means more performance
      Possibly faster to make or use less man hours
      Stronger for given resources more can be made
      very fast prototyping
      significantly less tooling cost lowers variant price

      The press analogy is right the bf109 was lighter than competitor fighters thanks to the heaver German forges.

        >Lighter means more performance
        This process cannot yet guarantee lighter end products, since the material quality is not yet proven.
        >Possibly faster to make or use less man hours
        Faster is not going to happen, additive manufacturing is slower than formative manufacturing by definition. It will take more man hours therefore, especially with being a non-mature tech.
        > for given resources more can be made
        It actually takes more resources since it's slower than forging/pressing. Therefore, the pressing analogy is terrible.

        The first boat it prints should be named Benchy.

        I mean, printed boats aren't new anymore - and Benchy-shaped boats sink.

      Tooling sized for small run high mix lots, because the Army refuses to buy in reasonable quantity. Enjoy your 10 new tanks per year.

    3d printed metals are about an order of magnitude less resistant to fatigue

    It seems nice for prototypes and tests. Useless for production.

      This machine is just the very first prototype. It's capabilities will improve as the technology matures. The Army mentions that in the future it could print full vehicle hulls nearly autonomously.

      this is what it will be used for, but I wish they'd use it to make custom hulls for special occasions. You could get some marketing tie-ins with disney, gaming studios, etc

      It's machines to make machines anon. You don't need it to be quick, you just use them to make more of itself on its own and have thousands of them.

          Additive friction stir deposition requires some amount of force, and on top of that the machine is also a giant multi axis mill.
