There was an article in the whatever this week about using a 3d printer in Hiati to make umbilicle clamps...and Im like..youve got electricity..laptops and a 3d printet and you cant buy plastic clamps...which you dont actually need because evolution sorted that one out a milion years ago.

Isn't creating such a barrel currently beyond the technology? What you can build at the moment are specific parts but you'd have to be a brave man to assemble and fire a printed gun - high likelihood of catastrophic failure.

This. All the hysteria about 3D guns and it turns out the one design in circulation was only the lower receiver anyway.

Yes, you could make a proper 3D pistol with a high-end 3D sintering machine, but if you had access to that kind of tech (and money), it would be less effort to hire ninjas.

The hobbyist 3D printers you can buy today aren't up to the job, and despite Job's fear mongering about high-end plastics, its not an issue because a. the kind of plastics you could use to make an (indifferent) gun are HUGELY expensive (a lot more than buying a gun off a bloke in a dodgy pub), and b. trackable because there are so few vendors and applications; it would be like buying semtex.

Duh..yes expensive now..but you should know how things develop..printer and plastic tech will be now be in overdrive

Its not the printer tech that matters, its the feedstock. And that will remain expensive and traceable for exotic applications.

 

[soze]

You can make simple guns without a 3D printer.

Big woop.

Oh and no plastic that can be 3D printed will leave marks on a metal bullet.

That is the point. The way they identify the gun used in a crime are by the firing pin and by by marks that are left by the barrel. As soon as you can print both parts from material that will let you fire 10 - 15 bullets it will make gun crime that much harder to solve.

I meant to quote. Someone said about melting them down after firing them.

Much worse than now when the same gun is rented to lots of different guys doing different crimes?

This is reminding me of LA Noire.

Yeah one deactivated gun could be used in 50 different crimes while leaving no currently usable evidence at all.

What no CCTV, no eye witnesses, no chemical traces on the shooters clothes, no dna, no traces of their clothing - all from changing the barrel

I was talking about 4 posts up about how they trace a bullet back to a gun. I did not think to continue that I had to specify each time that I was talking about the bullet.

Yep. The 3D printer gun thing is a rubbish non-story.

But its just one form of corroborating evidence - you are overplaying its importance - in many crimes the gun is never recovered.

No I am not (well I might have but I never meant to). I never said they will never solve another gun crime. I just said in cases where they track a bullet to a gun they are shagged. I am aware that they solve gun crimes in other ways.

But surely there are thousands of workshops in the UK that have the requisite tools to create barrels or just alter the rifling already if they wished? No one bothers because its easy enough to smuggle in small arms from mainland Europe.

I wouldn't say there are thousands. Rifling in particular is a very specialist machining process. In the US there are certainly thousands of hobbyists who have the right kit, but over here, not so much. It would be quite easy to make a smoothbore barrel, you just need access to chrome-moly or stainless steel and a decent lathe (and an annealing oven if you want to do it right), but to rifle it you need specialist skills - single cut rifling is a real skill and there are very few people who can do it, especially now manufacturing is on its arse, but the tools needed to do rifling the way its done in mass manufacturing (button rifling - which draws a tool through the bore to do the multiple lands all at once) are specialist - I had to learn how to make a machine to do this when I was an apprentice (not for rifling - I had to turn round holes into perfectly square ones, but the principle is the same), and you certainly can't buy them.

This is one reason why certain people are all excited about 3D, because it might take away all the specialist tools and training required, but 3D printers aren't replicators, we're a long way from rendering 3D plastics with the right strength, ductility and hardness characteristics needed to easily replace stainless steel etc.

Re-comissioning de-commissioned firearms is relatively easy though right? And thanks to no real border its easy to get stuff from the rest of europe - you could even ship it legally if you mis-describe the barrels on the manifest as steel tubing or something.

Edit: Oh and do you even need rifling for short range handguns? Rifling adds accuracy over range but up close?

A decommissioned gun is normally one that has no firing pin and the barrel is filled with a metal that gets into all the rifling of the barrel. To get it back you have to bore out the barrel. And if you get it wrong even by a fraction of a millimetre the gun can explode in your hand.

As to whether you need the rifling I have no idea on that one.

Do you guys want to make a thread about this? It's getting boring looking at the spam thread and not seeing funny pics or videos.

You don't really need rifling with a simple shot gun, which is all your average scumbag needs for a sawn off.

 

[Nate]

I agree, I don't see how that relates to the post you quoted. I'll go with it though.
