You can print your own guns at home. Next it will be nuclear weapons. Really.

Once again, with mass shootings in a church in Charleston, S.C., and a movie theater in Lafayette, La., Americans are discussing gun control — or discussing why we are not discussing it. With so many mass shootings and so little action, President Obama recently called gun-law reform the policy area in which he has “been the most frustrated and the most stymied.”

But technology is a bigger obstacle to reducing future gun deaths than either the National Rifle Association or differing interpretations of the Second Amendment. Within a few years, the greatest challenge to the government’s ability to control firearms will be advances in additive manufacturing, popularly known as “3-D printing.”
