3D Printed Metal Gun Fires 600 Rounds

This may seem off-topic on an LENR forum, but I think it is related.

An article on CNS News is reporting that Solid Concepts, a California 3D printing company has 3D printed a metal gun that has been able to successfully fire 600 rounds of ammunition. This quite an advanced from the plastic 3D printed Liberator gun that was in the news earlier this year, which did work, but exploded during a test.

Solid Concepts believes it is the only 3D printing gun manufacturer with a US license to make firearms.

Of course this is a controversial use of 3D printing — and many people are concerned about the way 3D printing could allow the underground production of deadly weapons rapidly and cheaply — something that will be increasingly difficult for law enforcement authorities to detect and prevent.

But in a wider context we are seeing that sophisticated 3D printing is making possible the proliferation of increasingly robust and sophisticated technology extremely rapidly. No longer do you need a factory, expensive and complex machining tools, and the expense of a workforce to manufacture. If we are thinking in terms of LENR — an E-Cat reactor is not a complex product, it seems only to consist of metal tubes with some plumbing and electronics attached, surely much easier than a gun to 3D print.

Of course we don’t yet know the recipe of making it operate, but if that secret is ever revealed or leaked, it should not be a terribly difficult matter for these kinds of reactors to be built en masse, in an unregulated way. The consequences of that are unknown, but could be extremely far-reaching.

It seems that we may be reaching a convergence of technologies that could have the effect of transforming our world in almost unimaginable ways.

    Why would law enforcement authorities need to ‘detect and prevent’ this? In the US, it’s been legal to make your own firearms since 1776, and thousand of gunsmiths make their own. As long as you are making them for yourself, no federal paperwork is required.

    I doubt underground gunsmiths selling weapons illegally in the US are going to need a $750k machine to do what a villager in Afghanistan can do with a set of hand tools and a drill press. Look up Darra Adam Khel to see what is possible even in the third world.

      We have readers here from all around the world — many countries have very strict firearms laws. The US is quite an exception when it comes to gun ownership and manufacturing.

      • Ash

        I guess. But you are in the US, and so is this company, and the activity described is a constitutionally protected right?

          This was primarily a proof of concept. That it could be done.
          Your right. No One is going to do much with this other then hobby & such.
          There are much cheaper & even simpler ways to manufacture guns & Many Machinists know how, have the equipment, And Many have made guns.

          I once new a guy who made all types of guns while waiting on auto lathes making other devices on his job.
          22 caliber Gatling gun, Mini canons that fired black powder or some that used shot shells. a 6 shooter that really was. It fired all 6 at once, Flint locks, Rifled, semi autos, Everything.

          Their simple enough that My brother & I made a single shot shotgun before the age of twelve. Just using common equipment & materials on the Farm.

          ! Note: Contrary to what one may see in the News- In the U.S., All Full automatic Weapons are Illegal. To Own, Possess, or Manufacture. There are Only a very Few Special Collectors allowed to have them & Are Required to have a Special License/Permit.

            Yes, the gun part is relatively simple. Ammunition however would not be possible with this technology. In any case, as Admin points out, the US is a special case as far as firearms are concerned. Most of the rest of the Western world has been disarmed to the point where even carrying a penkife is illegal. The UK is considered liberal because fairly low powered airguns are still permitted without licensing, but even this small freedom is under constant attack by a vociferous anti-anything-gun-shaped lobby supported by police misinformation.

              Ahh Peter.

              A penknife can get you in trouble here. Ha Ha..
              Even if pulled over for a traffic stop.
              When I was a Kid, The Odd Ball in school was the one who didn’t carry some kind of pocket knife.
              I recall in grade school, kids would pull out a pocket knife, but it was to whittle on wood. In Junior High, We were required to bring one to school for wood shop.

              Today, It can get you suspended from school & even arrested.
              But then, Back then nobody in school even considered pulling out a knife if you got in a fight. Different mentality.
              Back then, if the Guy was down, you stopped. Unless he came back up swinging. There was some honor. Don’t kick someone when their down.
              Today, if you go down, they kick stomp & others may even join in. It’s Crazy.

                Careful, OZ – we don’t want anyone thinking that half the people who post here are old dinosaurs who still live in a lost world of conkers, marbles, model aircraft and Webley air pistols (or US equivalents)..

                Even if it’s true.

              Bullets….
              We could make our own gunpowder & Lead shot.
              My Dad taught us to make the powder. Something he learned during lean times & couldn’t afford to buy it for splitting logs. He had hollow wedges with a fuse hole in the top. Put powder in the end & pound it into the log. Lite the fuse & run. Suckers fly 20 or 30 feet in the air.

              Home brew powder is tricky. Doesn’t always work. Sometimes you just get a lot of smoke. Sometimes your unsure what happened & just come back in an hour. LOL

              You have to be reasonably precise on the measuring. Likely I couldn’t do it today without a lot of experimenting. That was a long time ago. Shoot, Most of the time I have trouble remembering the Ingredients let alone the portions.
              Have to remember, It’s an Old Art from centuries ago.

              • Fortyniner

                In my mis-spent youth I always found a chlorate-sugar mix with an additional secret ingredient that I won’t specify here, was a good substitute. Fulminate impact primers might be tricky though.

    That’s an Expensive Gun. Original Article claimed the printer used cost $750K. It better Work!!!

    NASA 3D work…These 3D printers will make prototyping products much cheaper.
    NASA printed out a Rocket Injector. What normally cost $10K & 6 months Cost $5K & about 6 weeks. So turn around on design flaws can be much cheaper & quicker. Maybe NASA can finally stay on Budget & timelines. DOD, Pay attention. This includes you too.

    In 11 different hot-fire tests, the two 3D-printed injectors were subjected to a total of 46 seconds of firing time at temperatures nearing 6,000° F (3,316° C)./// This is misleading. The injector itself didn’t actually get that hot. Just the flame.\

    NOTE: Both the Gun & this nozzle required additional finishing work before put into operation.

    For consumers-It’s unlikely to ever be competitive for mass produced products. Also, Prototype costs are figured into product costs. This should be reflected it the consumer price. Some savings.
    They will also be cost effective for niche markets & custom projects/products. Also Products produced in small numbers.
    It will be great for parts repair/replacement for N/A parts. So you can use that appliance or whatever for another 5 years instead of buying a new one. Especially when it’s not in the budget.

    NOW- BIG Question. Will these printers eventually become so cheap that they become throw aways, But the Raw materials require sacrificing your 1st born?

    NO Idea why this comes to mind. 🙂
    And will the jets plug up in mid project???
    This has never happened to Me.(SARC)

    I am planning exactly this. Having been to the 3DPrint show last week, I am, on Tuesday, visiting one of the leading laser metal printers in the UK and have a theoretical reactor design sketched out that will be able to be printed in one piece. Trigger zone for arcing, potentially active surface, thermal conduction path, hermetic, homogenous core with holes for resistive heating, in built channels for fluid based thermal management/hear extraction space for insertion of nano powders / catalysts / phenanthrene / H2 storage.

    Will run a blog on it on the site when possible seeking proposed designs.

    Some things to get your creative juices flowing.

    – 20um layers
    – Fully vitrified walls of 600um (theoretically impermiable)
    – Components can be free with at least 150um
    – surface is exceptionally rough with 45um variation
    – component operation well over 1200ºC
    – 250mm X 250mm X 250mm build volume

    • Fortyniner

      Bob

      This is a test bed design? Or have you acquired some interesting new leads that may enable a functioning reactor to be built?

      This is the first time I’ve heard mention of phenanthrene (other organic compounds have been mentioned, but maybe I just haven’t been paying attention) – what is it for, and why not use benzene?

          It’s my opinion that the Gamma bursts are primarily when the Reaction initial starts & that it levels down shortly After. Maybe seconds as you have observed.

          I wonder if it spikes when the process is suddenly ramped up more after that point or does it stay stable. Would this be possibly why Rossi brings the Hot Cat up to temp slowly.

          I’ve worked with heat treating & Carbonizing Steel in the past & know that in certain processes the steel is brought to temp in stages to minimize metal stress. But now I wonder if in Rossi’s situation it has to do with Gamma Spiking. Guess it could be both.

          I would Add that I’ve read some info that Rossi has minimized the transmutation of Nickle to Copper(Fusion according to some which produces the Gamma) Near Zero & has reduced the Gamma spike. Thus much less shielding is required.

          And a Tid/Bit from Cures.(Google Trans ???) Rossi now uses 2 cores.
          Don’t no how the works. Core within a Core maybe. The Mouse
          And a new Triggering method. Heat is no longer the primary trigger & According to the Translation which You Know? May not be needed to trigger it at all.
          Cures seemed to indicate Neither of these 2 new changes were involved/used in the 3rd part tests. But again Google trans?

            In chemistry, some reactions do not take place unless proportions of reactants are in the right ranges or the temperature is very closely held within certain ranges. If you don’t get things right, you can end up with very undesirable side effects or the wrong reactions occurring.

            Additionally having chemicals in the right structure to begin with is very important.

            In LENR, these constraints may still be also very relevant, however, additionally, magnetic, electrostatic and ionising variables may come into play.

        • Fortyniner

          Thanks. It rather looks like any PAH probably would do, as there doesn’t seem to be anything special about phenanthrene chemically that would make it more subject to what looks suspiciously like a low energy C-H fusion event. Probably all that is required is the benzene ring structure with its peculiar bonding. Mizuno et al. stop short of directly suggesting this possibility though, other than a brief reference to the appearance of what ‘might’ be carbon-13. Edison would approve of their approach.

          Interestingly this phenomenon may possibly be connected to Rossi’s work on his catalytic pressure reactor, the ‘Petrol Dragon’ – perhaps his interest in CF began when he observed anomolous heat coming from his experiments with this process.
