As has been amply reported in PlasticsToday, 3D printing is a truly remarkable technology that has had a profound impact on everything from medical manufacturing to moldmaking. But part of me wants to believe that, perhaps, its greatest and most elegant achievement is a machine gun that takes sheets of paper, folds them into airplanes, and shoots them into space.
Dieter Michael Krone, a mechanical engineer from Düsseldorf, Germany, describes the invention in this way on YouTube: "A little tinkering from me that shows what you can do with 3D printers today. Most parts of this paper airplane machine gun [were] printed by [3D printing services provider] fabberhouse.de." The other parts can be purchased online or at a hardware store, he adds. Krone does not, however, share information on how you might go about printing one of these babies on your own.
