Clearly it'll be a while before 3D printers are more systemically present and achievable purchases for many within society, but with the proven potential to make your own gun, and the potential liberalisation of accessibility to such weaponry... ...is there anything for us to be concerned about?

People have been making their own guns for years.
So long as you are willing to put up with crap accuracy and chance of it blowing up in your hand.
Not sure a 3d printer variant makes that much difference.

Yes, but its about activation energy isn't it. I mean, I made loads of stuff out of the jolly roger cook book when I was young, when I had lots of time, energy and curiousity, though I didn't make a gun, as I didn't have access to the metal tools or plans. Surely this significantly reduces the activation energy.. ..kids might not be making bow and arrows, but downloading the free to access plans and printing their own....

Well yes, he describes himself as some kind of anarchist, and values that it won't be possible to control the accessibility to these weapons, which I find quite frightening. People always come back to the.. .."well its the man, not the weapon that kills", which is true, but there is a huge psychological difference between making physical contact with someone to their detriment, through hands of a held weapon, and being able to do so at a relative distance.

Home made black powder wouldnt be that difficult either although the power would be so so.

One thought that came to my mind was that it would probably be quite easy for someone who knows how to do such things to hack into the published designs and render them inoperable, or to blow up in the users hand when the trigger is pulled.

My thoughts entirely.
I'm not that familiar with ABS but I'm guessing that you can just grind it down and reuse it.
Queue thousands of murders with no murder weapon ever found.
In the UK at least possesion of a hand gun will get you a prison sentance so it's not really relevant. Getting a gun is easy and not really a deterrent to someone with determination, it's the penalty for possession which is supposed to be the deterrent.
I'm looking forward to the day when something breaks and I can actually fix it again. Recycling in the home will become reality.

For the gun he has made you are probably right. But as 3D printers become more advanced and can print in stronger materials the gun designs will advance and advance. We'll be in world where any kid can download a lethal weapon and build it at home. The problem could well be the bullets for now but I'm sure people will find ways and means.
The thing is, it can't be stopped, 3D printers will in time become cheaper and better and eventually in every home and although I'm sure there will be rules on what you can and can't print off there will always be illegal sites where people can download whatever they like.

It's a crude device but deadly and unnecessary all the same, there's hardly any science there, just another means of avoiding gun control. The mindset of the american gun activist is just bewildering, in that they simply cannot take the weapons for what they are. The same people who continue preaching and practising a bizzare and quite frankly ridiculous lifestyle defined by firearms.
And with kit like this...
http://www.wimp.com/functionaltools/
It wont be long before one can scan more complex weapon components and produce them.
I also noticed in the comments, a chap sends his 7 year old daughter to school with a 'special' (assume he means .38 spc) in her lunchbox...
We have it relatively good here on this side of the pond, we really do!

In reply to Jimbo W: He just saying that people are hiding their identities.
No doubt they are clearing their browser histories and wiping their hard drives regularly.
As I say. Lots of us don't want to kill people because we don't want to kill people. A very few people don't want to kill people because they might get caught. Even fewer people kill people and don't care if they get caught.
Worrying about printing guns, or Challenger Tanks is not worth doing, it won't change people's mindset.

In reply to DancingOnRock: Surely proliferation has its risks however. US, virtually uncontrolled gun ownership = huge annual tally of gun deaths. UK controlled = low annual tally.
Technology allowing relatively easy circumvention of control could increase number of guns available and increase the number of feckless fools who couldn't conveniently get one before, getting one (or walter mitty's who just want to have one who then loose it/have it stolen) leading to increased gun deaths amoungst the fools, innocent bystanders and a general increase in armed robbery etc.
There are lot of fools out there who plead 'but I didn't mean to kill him' after stabbing somebody or kicking them repeatedly in the head... those same people will cheerfully carry around a plastic gun without 'meaning' to kill anybody. Then will.
Agreed, a knife or brick may be as effective but why make life easier for anybody to obtain something that is utterly unnecessary.

Break..don't know.
I don't think the barrel can really have much rifling effect on the bullet though, I'd be very surprised if it did more than vaguely keep it going in the right direction while sustaining a lot of damage from the bullet itself and then from the hot exhaust gases.

rifling isnt essential but it makes it a damn sight more accurate.

WEP is a broken security protocol. Insanely easy to crack nowadays so if you still have it change it.
However lots of people still have it, so all you would need for some "anonymous" browsing is find someone with a WEP wireless connection, crack it and then log on to dubious site and do your downloads. If the cops are monitoring means that poor sod gets the visit.
TOR and VPNs are just ways of bouncing around your own connection in a secure way to make it a lot more difficult for anyone to monitor. Not impossible but would need motivation.

Some info here.
It's a way of creating 3 dimensional objects by laying down thin layers of some sort of plastic of photimageable polymer (something that starts as a liquid but turns to solid when you shine a light on it).
It allows you to make all sorts of objects using one machine, all you need is a 3 dimensional representation of the the thing you want to make.

In reply to DancingOnRock: As far as downloading goes, people can cover there tracks but they wouldn't really have to. A 3D printing file is just a file filled with plotting data for a 3D printer. It's just data, they wouldn't be able to tell part it's going to print off unless they got the file themselves , and besides if someone puts the file online and 500,000 people download it all across the country in the first 24 hours what are they going to do, arrest everyone?

this will have to evolve a fair bit before it becomes attractive to anyone more than sociopathic nerds, tho sadly they seem to fit the profile of many who blow away kids iin schoolrooms....
