  •  I don't think these last very long..... (7+ / 0-)

    they said they worked for about 6 bullets on the average.  I also doubt if they are effective at longer ranges.  Cheap saturday night specials are also not very effective weapons exceot at close range and they also get the job done.

    I think these won't replace most firearms but will be made to freak people out.  Less likely to kill a toddler than most of the current firearms.

      Once they get a reliable design then it will be worth researching stronger composite materials.

          One of the goals of this technology is to be able to print working machinery parts with a high level of calibration and accuracy.  

          We need printable materials that can hold up close to steel and there are a LOT of people trying to crack that nut.

            But that's a ways off.  For now, we are talking about a prototyping tool, and not much else.

            My worry is different, use 3D printers to make the jigs that people can use in their metal shop to make guns that, while not professional, are pretty good.

            Alll that said, until guns are banned, there is no reason to use an inferior plastic gun, or plastic jigs...and guns are not gonna get the whole thing is really just a side show.

            •  A major reason - they're hard to detect (1+ / 0-)

              and hard to trace.  No, they won't be good for sportsmen, for hunting or probably even for self-defense, but for all those metal detectors out there, or for gangsters who want to avoid any measures like traceability, these will be used and they will be valued (which will make inventive people work to produce them).  Look at the gun used in the movie "In the Line of Fire" where Clint Eastwood was in the Secret Service and John Malkovich had plastic components to a gun that he assembled after going through a metal detector - with these 3D guns you wouldn't even need that much misdirection and as I said in another post, people trying to be sneaky will find ways to fashion the guns to look like other things wholly unexpected to be a gun.  They don't need it to work for more than a shot or two if they're at close range.

      •  Try using a little imagination in respect to (1+ / 0-)
        Recommended by:

        various forms of fabrication that could be employed to make a lethal gun capable of many shots on target. One method I can think of off hand is a super Air gun. Currently we have air guns which are some what limited in terms of exit muzzle velocity, simply because air guns are manufactured like regular firearms. The only difference is that they use air instead of black powder to propel the bullet. With 3D printing capability a new crop of designers will be able to work on radically new designs that use air for propulsion and are magnitudes more efficient in the storage and release of that air through uniquely designed firing platforms. A muzzle velocity of 1400 to 1500 feet per second would be a very respectible gun. With computers and 3D printers anything is now possible.

      of the technology. It will continue to improve. It is the PERFECT way to produce a disposable murder weapon. But for folks who check under their bed every night for commies and brown people, the technology is a god-send. A 100% UNTRACEABLE, UNREGISTERED weapon.

      As the tech improves, more people will buy this and make their own arsenal, rather than buy serialized, "registered" firearms from manufacturers.

      This the gun industry cannot allow.

      •  they will invest in the technology instead. nt (0+ / 0-)
        •  And how will they justify to the goverment (0+ / 0-)

          and the public that they are now in the business of producing untraceable weapons perfect for assassins and terrorists?

          The courts have always ruled that things like serial numbers are perfectly Constitutional, and making "print your own gun" machines is too big a stretch even for the gun industry.

          Also, this is a completely different business model and dynamic. Unlikely they will be able to adapt. Hollywood and the recording industry are certainly having a hard time.

    •  The name "Liberator" ought to be the tip off ... (4+ / 0-)

      During the Second World War, the OSS distributed a few thousand of these things.

      It was a gesture.  It was a fetish.  It probably made some members of Resistance movements feel better armed ... though a garotte and  a  sharp chef's knife would  have been a more effective weapon system.

      OK ... so now we've got a collective  of Armchair Anarchists offering a way for equally harmless techies to commit a secret act of civil disobedience by manufacturing a gun-like object they have no intention of using.  

      That's about on the level of smoking a joint in your Mom's basement to show your contempt for Richard Nixon and all his works:  Accomplishes nothing, harms noone.

      I'm not too scared.

      On the other hand ... what 3-d printers can do, and have done, is fabricate the "lower receiver" and "slide" assemblies for the AK and AR types of long gun.  As shown on U-Tube, the weapons were street-legal
       (except for the "illegal manufacture of a firearm offense) semi-automatic rifles with store-bought locks, stocks and barrels.

      However, in theory at least a couple of simple changes to the CAD file transforms the civilian AR to full-auto or select fire weapon.  In practice, the conversion calls for more than a little skill and gunsmithing experience.  But the 3-d technology for about $8,000 eliminates the need for a milling machine costing about $2,000.

      But, if it allows some fantisizers to imagine they're big bad Revolutionary Prepared Patriot heroes ... the vast majority will never ever harm anyone except members of their own families.

        but as I pointed out above, you are dealing in facts, while I am speaking of perceptions. These people are all about form over substance.

      •  You don't even need the milling machine. (0+ / 0-)

        AFAIK you can order lower receiver 'blanks' that are fully machined but lack a few holes that need to be drilled & tapped -- something you can do with less than a hundred bucks in tools from Harbor Freight.

        •  Ouch ! (0+ / 0-)

          I don't read Shotgun News anymore but I do get the Sportsman's Guide ... which is a pretty middle of the road mail order company for outdoorspeople.

          It wasn't all that long ago they were offering small discounts on the bump-fire stock for the AR-15 ... they still offer "unfinished" slides for a Polish weapon I don't know anything about.  (I'm assuming it's another AK variation from the Cold War era.)
