Defence Distributed Demonstrates 3D Printed "High Capacity" AR15 Magazine on youtube

Technology is making the desire to keep detachable magazines out of the hands of rampage shooters an impossibility. It has always been possible for people to make magazines of more than 10 rounds in home workshops. Magazines for AR15 rifles were made in jungle workshops by the Viet Cong. But in today's digital society, especially among young, hip, technologically advanced adults, nothing catches the attention like the ability to print working magazines for modern rifles by pressing a button on a 3D printer.

Defence distributed has now released digital files that enable people to print magazines for their AR15 rifle at home on their own 3D printer. Printing magazines is far easier than printing entire rifles; magazines are, in effect, only a box with a spring, and 3D printers make getting the dimensions correct as easy as pressing a button.

In the video, the magazine is demonstrated not only firing on semi-auto, but also on fully auto.

Have you decided that we must now have 3D printer control? That is rather difficult, as many of the latest at home 3D printers are capable of duplicating themselves. They are currently available for less than $1000, and the price is dropping.

If your buddy needs a 3D printer, it may take a week or so to print and assemble his, but it can be done without ordering it from a retail store or off of the net.

It appears that magazine control now makes less sense than outlawing kitchen knives.

kitchen knives.

Kitchen knives are arms and therefore covered by the 2nd amendment. ;)

Yes they are, and 3D printers should be protected under both the First and Second Amendments! ;-)

Downloaded. Never can tell when I might want to buy a 3-d printer and run off a bunch.

In combat durability and reliability is critical. So I do not see these magazines catching on.

Criminals who only intend to use the magazine once do not need as much durability as a combat infantryman.

This technology makes restricting magazines from rampage shooters a silly dream... It always ways, but most people can understand this easier.

It's early days in the home 3-D printer world. Think Timex-Sinclair in PC terms.

Gotta love those Defense Distributed guys. They really know how to give the tech wedgie to the gun grabbers.

"In combat durability and reliability is critical"

Not as much of a concern, when one can print themselves as many magazines as one has cartridges to fill them with.

bump fer later

OK I'm slow. I realize this thing does not use ‘ink’ so just how much does a cartridge of (?) for the printer cost? How much can you get out of it before you need a refill? (so to speak)
Is this even financially viable? Print your own what ever for $1000? or just buy one already made for $100?

This can't be cheap to run....

Sorry, I do not have a link, but I recall that prices for the material varies per the technology used.

I recall that the price of a printed magazine would be around $10.

There's a lot of work being done on using recyclable plastic in these things. How 'bout them apples? Take a few two-liter coke bottles, and you got yerself a magazine for essentially nothing!

A Von Neumann machine.

Semi-Von Newmann machine... still requires human intervention.
