content: Shoot, you do not need such high tech to make a gun. All you need are basic tools for metalwork, files,drills,hacksaws. You can buy guns in Afghanistan that are made by backyard smiths, who have nothing else, no power tools, no lathes nothing.Any half decent metalworker can turn them out easy enough. Here they are made by shack dwellers who have little other than basic tooling and some ammunition.

content: Been predicting this from the first moment I heard of 3D printing (naturally, as I have worked as a gunsmith in the past).The AR-15 lower receiver is some of the lowest-hanging fruit in the firearms world re: 3D printing. Its somewhat complex but not highly stressed at all. There are already commercially available plastic lowers on the market that work pretty well.Once you can start printing, say, aluminum or any kind of steel at home, the sky is the limit.

The music industries failure to do so has cost it dearly.Re: the future of 3S printing firearms...Its difficult to shift making parts (and firearms parts, in particular) from one manufacturing technology base to another. As an example, the AR-15 lower is machined from a forged piece of 7075 aluminum, then hard anodized. That methodology is what it is what its dimensions and tolerances reflect, so there are no-doubt pitfalls in 3D printing one. Other already existing parts and firearms overall may prove impossible to do so with present or future 3D printing technology.Now, when some clever soul designs and engineers guns that are meant to be 3D printed in their entirety....its going to get interesting.

content: My old employer sent me a link to a video last evening on youtube on 3d printing. You might have seen it with the guy getting a crescent wrench copied. It didn't make sense the way it was presented as scanning a complete product rather then the individual parts scanned and fitted individually after printing, only to pull out a completely working wrench out of a pile of dust that works. I call total bullshit on this one. This is nothing like the video I seen of some prototype parts manufacture at Boeing a few months ago.However, the handwriting is on the wall for a lot of machinists,foundries,and mold shops. This will be a very disruptive technology once perfected and there is a highly unlikelyhood a machinist is going to retrain in CAD. On the other end of the equation is the designers that have been working in CAD for two decades and this is going to be an evolutionary progression. More skilled jobs out the door.

content: The job shift has been happening for years now. A machinist these days needs to be more computer programmer than machinist these days due to CNC/CAM. Even going back to the plug board machines of the 50's and 60's the machinist needed to be more electrician electronics engineer than machine setter as required with capstan lathes.Electronic engineers now need to be more a computer programmer CAD operator than an electronic engineer of 20 or 30 years ago.It will continue to progress that way until we come up up with computers capable of creativity then the human factor will be out of the loop but until then it will still be humans who have the idea just that the actual design and making will be done on computers.

content: I wouldn't be surprised if some politician already speaks about forbidding 3D printing.Most certainly with a lawyer/economist/catholic background.Like these master/slave fundamentalists :http://edition.cnn.com/2003/TECH/ptech/11/26/master.term.reut/

content: I note from the link that repatriation of decedents of slaves is also under consideration so in one move they have gone from leftist political correctness on the master/slave hard drive issue to neo Natzi and want to repatriate the decedents of slaves (deport).I get the impression that in California there are people with nothing to do other than come up with useless crazy ideas.

content: I mis read that one. But it would not surprise me if they did try deportations, there are a lot of nuts about. Reparations for what in any case, sorry we forced your ancestors here and now you are president.
