Wow, now that's a lot of attitude! I do feel sorry for those 250 engineers you know though. You could have ignored this of course, but no, you couldn't. You had to throw your 2 cents in to let everyone know just how right-wing you are, never to miss just such an opportunity. Besides, this is an issue for engineers to discuss just as was the nuclear bomb for physicists. Enjoy!
A company in South Africa is aready looking at 3D printing for Military hardware. They are working out the details of using laser sinturing to build parts for a military drone aircraft.
While we spend all our energy worrying about how a civilian might use this technology to create a low production weapon, what about any governments ability to mass produce weapons and use them on the civilians?
Engineers and scientists have produced many things over the years with no thought as to how they could be misused, of maybe without imagining how they could be misused only to have various governments gladly pay for a way to weaponize them. Aircraft - much of the early development was funded by governements to use as weapons. But we still use them for peaceful putposes every day. Nobel - explosives used in mining only to be weaponized by governments going to war.
And lets look at the things that truly create dangers for peopel. Guns are not the first thing on the list, but they are the first thing that many would do something about. What about the dangers brought about by alchohol? or Drugs? or Baseball bats? Or are we just more comfortable with those things and better conditioned to not see the misuse of other common objects?
Lets apply some of that engineers logic and analysis and be a bit less knee-jerk and more level headed in our approach.
Quacker, I'll grant that your concerns may be completely warranted. So, what could be proposed to stuff this genie back in to the bottle? I mean, short of forming a complete police state, what could possibly stop this?
Shall we license the use of servo and stepper motors? Shall we license the use of heated nozzles for plastic? How would we control or track these 3D printers? Worse, how would we know what the parts it makes are for?
The reality is that people have always had the ability to build offensive weapons in their basements and garages. The only thing that keeps us civil is a belief in the value of civilization. Regardless of whether one is religious or not, it is very important to teach civility.
Yes, the veneer of civilization really is that thin. It is indeed very easy to forget this fact. But the existence of a 3D printer is no more a threat than a hardware store. I'm not trivilizing the possibility. There will be attacks like Oklahoma City. And yet, we can't ban the use of ammonium nitrate or fuel oil either.
look up King Gusavus Adolphus of Sweden and his cannons made of leather dating from the 1600's. It says something that a cheap leather cannon that lasts for about 20 rounds lasted longer than an expensive 3d part that lasts for 3. Sure Iron tubes replaced them but it was still an interesting technical achievement.
I agree, it's not like anything new is happening from a legal standpoint. The use of a 3-D printer will not require any laws to be changed or added.
Reading the source article is highly recommended, folks! This plastic lower broke during initial assembly, many holes were intentionally under-sized & needed to be drilled, reamed, threaded & tapped. This project was not a 'print & go' gun but is just a hobbiests venture to push into new frontiers.
The source article has a series of comments worth reading, as well. Looks like a very serious community is referenced there, who will continue this kind of development individually no matter what anyone here might think of it.
The file which was downloaded from thingiverse to make this receiver lower resulted in the thingiverse site owners to issue a ban on any future weapon files from being uploaded. I expect this kind of reaction will become a standard for any widespread public forum which I think is a fair reaction. The only people who really are pioneering this kind of technology will continue to share their files on specialty forums, which will limit the public impact.
The printing of a firearm will not be the first thing a common criminal will choose as a way to arm themselves, but I'm sure they will be reading about it! The fact that a printed firearm has no registered serial number, might be interesting to a higher class of criminal. Just take a look at the rapidly booming specialty of 3-D printing ATM scanners, which are designed to fit perfectly on top of an ATM's keypad and allow a 'man in the middle' attack to steal your login details. These scanners are being developed by organized groups who obtain 3-D printers any which way they can. These groups are using these printers specifically to break the law, and for no further use. I would bet they will be thinking about printing weapons.
There's a huge market south of the border looking for any kind of firearm. I can see how the fact that a weapon might break after a couple shots will not matter to someone who will mix 5 pounds of baking soda with a couple ounces of crack cocaine just to increase their profit margins. So I expect to see some kind of funny business in the near future. Maybe a hostage situation where the guy holding the hostage cant take it any longer, pulls his trigger and the gun falls apart. He'll be thinking about how he got ripped-off for a bogus weapon while getting a free trip to the state holiday inn!
I agree. As always, it isn't the gun, it is the nut behind it.
But, I have purchased several ceramic knives in ny Japan visits over the last several years that are so sharp and deadly I would place them in the same catagory as a gun. I could probably get these thru the metal detector easily. So I won't worry about synthetic guns. Remember, knives don't kill. People and governments do...
Festo's BionicKangaroo combines pneumatic and electrical drive technology, plus very precise controls and condition monitoring. Like a real kangaroo, the BionicKangaroo robot harvests the kinetic energy of each takeoff and immediately uses it to power the next jump.
