3-d printed high-capacity magazines

In class Monday we talked for a moment about whether and how news stories about new technology could be ethically significant. I said that if technology changes the ways we live and interact with each other, then a new piece of technology might be very ethically significant.

Here is a great example. Forbes has an interesting write-up about Defense Distributed, a group using 3-d printers to create high-capacity ammunition magazines. (See also this article at The Verge.) People are using 3-d printers to print high-capacity magazines to hold bullets for assault rifles. Magazines holding more than ten rounds used to be banned. Since the Newtown shooting, there is growing support for banning them again. Well, how effective would a ban be if people could just download the design and print one from home?

Of course this issue goes well-beyond just gun magazines or even firearms in general. 3-d printing promises to allow DIYers to manufacture things that, up to now, have had to come from large factories. In many ways, this should be great. But what about people who want to manufacture something illegal or dangerous?
