Meanwhile, the price and capacity of small "mini-mills" is coming down, to the point where a desk top sized mill is "affordable" for the serious "hobbyist." With one of those, it is possible to replicate a "real" firearm, without the worry that the plastic is going to some day catastrophically fail. i -- pyotr filipivich. Discussing the decline in the US's tech edge, James Niccol once wrote "It used to be that the USA was pretty good at producing stuff teenaged boys could lose a finger or two playing with." |

The last time I looked one could buy a lot of guns for the price of a 3D printer :-) From the pictures it looks like a single shot "zip-gun" and those can be made in any home shop for almost nothing. -- Cheers, John B. |

Some of this is the hypothetical "but they *could* do...," after which someone points out the ubiquity of CNC machining centers and the large size of basements in McMansions. g Criminals and nutjobs are not likely to learn machining, metallurgy, and programming just to build a gun. If it made any sense, they could do that now, and ersatz grease guns would be used in 7-Eleven stickups throughout the country. "Printing" a gun is something else, but, as several people have pointed out, you can make a zip gun now out of parts you can find at Home Depot. It's mostly wish-fulfillment and silly political argument. -- Ed Huntress |

How about $1300 at Staples: http://www.staples.com/Cube-3D-Print...duct_SS2044291 You can also now get a 3D scanner for $600: http://www.matterform.net/ Apparently one of the issues with the cheap printers is the degree to which the layer being drawn fuses securely to the layer below. These things are basically a CNC hot melt glue gun, and if the material laid down in the previous pass is too cool, the next layer doesn't stick as well as it might. The more expensive machines basically operate in an oven, so the material doesn't cool as much between passes. IF you decide to print a zip gun like this, I suspect the low end printers would produce a dangerously less robust version than with a high end printer. Doug White |

Doug White Why spend $1300 when you have been able to buy a plastic 12 gauge piston (flare gun) for many years. Or better yet make a zip gun out of scraps, a piece of brass tubing, a bent nail, some rubber bands and a piece of wood. -- Cheers, John B. |

This is actually an updated version that can be printed on cheaper machines. But how much do the "cheaper" machines cost. The last time I looked one could buy a lot of guns for the price of a 3D printer :-) True..but its hard to buy a lot of guns that have zero detection signature. That has to add a fair amount of "value" for some people. From the pictures it looks like a single shot "zip-gun" and those can be made in any home shop for almost nothing. True indeed. However...they show up on metal detectors. The printed gun was never designed to be a "threat to the public"..but a warning shot fired across the governments bows. And the Government acted EXACTLY as the builders believed they would. Which means that the Government is as predictable as a chronometer and it shows that the Constitution means **** to them in fact and in deed. So much for that pesky First AND Second Amendments...which the designers called exactly spot on. And it also showed the people..that the lumbering behemoth we call Government is virtually helpless. Which is why Im amused by the Leftwingers who threaten the People with Hornet aircraft and Rockeye bombs and so forth. To use them to attack revolutionaries...means the government kills endless piles of the innocent and their very own supporters to maybe..maybe kill one insurectionist. They simply dont think..they simply threaten..and dont understand its an empty threat. "If you *******s dont knock it off..we are going to nuke LA!!" Go ahead..you will kill millions of the innocent..and millions of Democrat voters. Not a bad trade for a couple insurectionists and the now directed hatred of more millions of the survivors towards the government. A propaganda coup of the century! The Left simply doesnt understand what Aysemetrical Warfare is...and why America is such a marvelous place for it to be employed...and such a miserable, deadly place for it to be defended against. -- "You guess the truth hurts? Really? "Hurt" aint the word. For Liberals, the truth is like salt to a slug. Sunlight to a vampire. Raid® to a cockroach. Sheriff Brody to a shark Bush to a Liberal The truth doesn't just hurt. It's painful, like a red hot poker shoved up their ass. Like sliding down a hundred foot razor blade using their dick as a brake. They HATE the truth." |

However...they show up on metal detectors. So? Make the barrel out of plastic than. The whole thing is a tempest in a tea pot and if you are really into the machine business you know it too. How long, and how much money, to drill a hole lengthwise through, say a 1 inch diameter fiberglass rod, 3 inches long. Whittle out an 'L' shaped of wood for a stock, bend a nail for the hammer and some rubber bands for the hammer spring. I'll bet is appreciably cheaper than the 3D printer :-) -- Cheers, John B. |

The problem is that the Powers That Be -want- the bad guys to act out so they can engage Martial Law. How many of the recent decades' terrorist acts on US soil were devised or encouraged by our good old fed gov't (or the powers behind it?) I'm not at all encouraged by the results of my research along those lines.
