I remember watching a show on the discovery channel where they made a monkey wrench out of polymer and thought it was amazing. Then I read an article about them being able to “print out” drugs and thought, great, lower the cost of pharmaceuticals, but the problem I see is a country there is no copy right infringement law deciding to pump out, like in the example in this article, warhammer figurines. Then importing them to countries for half hte price of the real deal. We already see it with electronics and clothing knock offs but the material costs for these 3D printers seem like they will be significantly cheaper. Only time will tell I guess.
