The means to manufacture weapons (guns) has been available to most people at the cost of 1-2K USD in machining equipment and a little ingenuity.

For example, some interesting submachine gun plans here http://thehomegunsmith.com/

I've had an idea for a Six Shooter Shotgun made from pipes floating around my head for the last couple of days (making a single shot - shotgun requires some steel pipes, a bit of wod and a nail).

The most difficult part to machine is the rifling in the barrel (the lack of which makes the above sub-machine gun very innacurate).

All 3D printers do is bring this ability to someone who doesn't do metalwork.

Really I'm surprised that there are not traveling arms factories drifting around places like the US, UK and other countries, they'd make a fortune pumping out cheap, low quality guns and ammo.

Well, I'm not sure that there aren't. I don't travel in the gun-heavy circles, so I don't know, but I find it hard to believe that this isn't becoming popular. I guess I'll visit the next local gun show and ask around.

When technology evolves to the point that everyone has the ability to give themselves the tech to build a device in their own garage that can blow the world up, it stands to reason that there will be at least one that will do so. Is that exciting, or is it definitely not so exciting?

The excitement level is irrelevant. The important part, is that this IS a possibility. And that the appropriate response is NOT totalitarian police states for all, just because you fear the possibility.

And for the umpteenth time, if you believe it is, you are wasting your time espousing such a sentiment here.

As far as 3d printing of guns? Yes, totally excited about it. I'm looking forward to acquiring a 3d printer even more now. Cheesy

So I wonder how long before they make fully automatic suppressed guns? Will teflon tipped rounds be far behind? Here's another disruptive technology that is outpacing the ability of governments to control.

Any significantly advanced cryptocurrency is indistinguishable from Ponzi Tulips.

Printing a complete, functioning firearm is a far cry from an AR-15 lower. Do you realize what kind of pressure levels that the chamber and barrel must withstand?

A decent machine shop can make all kinds of firearms today though. As far as suppression goes, that depends heavily on the ammunition.

Teflon coated bullets are pure media hype. The rounds were armor piercing because of the tungsten alloy they were made from. The teflon coating was used to help reduce barrel wear. Most high powered rifle rounds, which can be purchased just about anywhere today, are armor piercing.

3d printers will never make something capable of withstanding firing pressures. Now, home CNC machines.... that's a little more likely. The thing is, a "machine shop" is getting to the point where it's hobby-level stuff. Where two decades ago, a hobbyist might have had a router, maybe a lathe, two decades from now they're going to have a CNC, and 3d printer, and who knows what else. Hobbyists will be able to churn out anything from a drone aircraft to a fully functional firearm, in just a few days in the workshop. Media attention has so far focused on the impact of that fact on the manufacturing industry, but neglected its impact on government.
