"A pair of MIT mechanical engineering students has developed the first truly portable 3D printer, which fits neatly into a metal briefcase. PopFab—designed by MIT CADLab's Ilan Moyer and Nadya Peek of MIT's Centre for Bits and Atoms—can impressively be set up in just a few moments. In the embedded video you can see the students pull out a retractable arm, fix it in place, then connect up a laptop along with the printing head and attached material source. The pair then sit back and watch the device spring into action, etching out the fish design being fed to it by the laptop." - × × ×
