      Yes, it very much is. You're missing the slashes though. A common mistake for "newbs" !

        Please understand, 3d printing is amazing and it's the future. Soon you won't buy physical goods but just download an instruction that will print itself in your home. Everything must be 3d printed and 3d printing must be used for all applications.

            As someone who looked into the hype when it was at it's peak, 3D printing never took off because the original hype wave was a marketing ploy to sell outdated overpriced printers to nerdy "eArLy AdOpTeRs" and kickstart the industry
            .
            The industry state today is booming, with caveats
            1) Only unique items are 3D printed. Cheap, mass produced parts are more economically made by classical methods like stamping.
            2) Most industrial printers are metal alloy or engineered ceramics printers. They don't print shitty PVC.
            If there was big money to be made printing PVC on obsolete 3D printers, nobody would sell them.

              I'm half joking, I understand it's got some really useful applications in small scale production and prototyping stages.
              The people I know who home 3d print stuff are the ones I'm mocking, where they sing it's praises endlessly but just use it to make absolute shite.

              Yeah there's absolutely zero good reason for anyone to be printing casings for historical ammo that can't be readily bought today.

              Why? Simple. You don't NEED it

              They haven't '3d printed out of production ammo' they 3d printed something that resembles it. The True Velocity ammo that was in the NGSW trials will be the future of producing dead and exotic ammunition.

                Yes, the stated goal. To fit the cannon.

                >future of producing dead and exotic ammunition.
                You are dismissing a simple polymer-cased ammo hack and stating that polymer-cased ammo will be the future in the same breath.

                Just because they are both made out of polymers doesn't mean they are the same.
                Someone printed something that reassembled the original (they even printed the fricking letters on) and it fits down a Canon barrel. It wouldn't work in any sort of self loading firearm due to its being horrendously out of spec.
                The proper industrial process with True Velcocity does actually work though. I'm knocking hobbyists who think their shitty extruded plastic is the answer to everything, not the actual correct industrial applications that produce working products.

                Yes, you're being deliberately obtuse and getting mad about people you made up in your head who aren't in the conversation. Everyone understands this.

                The picture in the OP is literally what I'm describing though. Why are you sticking up for print gays so much.

                It's a neat little project from some no-name youtuber. Having the same expectations for, and demands of, random hobby projects and commercial mega-programs like the ceramic composite ammo for the entire US Army is deeply stupid.

              Stamping isn't even all that economic anymore, when you can get just enough strength out of injected molded polymers and make stuff cheap enough that it can just be replaced. Just the other day I saw some reel/short of a dude pounding a hammer into a car hood and the cosmetic panel was fiberglass instead of stamped metal like the structural part.

                Not him but the point being that 3D printing is still very much a niche and not very suited for much beyond very small batch production and one off prototypes and even that is kind of hindering newbie engineers who can't think in terms of production and just focus on what is potentially possible at an unacceptably high unit price.

    Shoot a stack of printer paper to test for penetration depth.
    Use at least ten inches of paper duct taped together strongly, so you can see exactly how far it penetrated.

    What's the fricking point if the projectile isn't even metal lmao? Just get some bar-stock and lathe that b***h to size. Bam, WW2 tank round, minus the heat-treatment.

    I cant imagine a plastic round is going to see the same terrific velocity increases you might get with smokeless powder in a modern gun, at least without a much longer barrel.

    Still, it'd be interesting to know the velocity, though almost impossible to measure safely.
    I'd wager a 50% increase over a lead projectile. Not enough to offset the light weight, anyway.
