cylonlover writes "There are plenty of different 3D printers to choose from these days, from the popular Makerbot Thing-O-Matic to the budget-priced Solidoodle. These all have one drawback, however, in that they aren't exactly portable. Most need to be disassembled to be moved, and even the fully-assembled Cubify printer isn't really built for travel. But now, two MIT students have developed the PopFab, a machine that does 3D printing and more, all while fitting inside a small suitcase. With different heads, the machine could also be used for milling, vinyl cutting, drawing, and much more, to create a wide variety of objects. The creators have also tested its portability by traveling with it as a carry-on suitcase to Saudi Arabia, Germany, and within the U.S."
