Technology is getting smarter by the day and some gadgets are on their way to becoming more and more portable. Two students, Ilan Moyer and Nadya Peek, from the MIT CADLab and MIT Center for Bits and Atoms respectively have built a 3D printer that can fit into a briefcase. They claim PopFab, the 3D printer, has traveled the world "as a carry-on item of luggage" to Saudi Arabia and Germany, and within the USA to Aspen in Colorado. In a video of their portable 3D printer, wherein the students introduce the PopFab, it is described as a multi-tool for the 21st century. The video says, "At its heart is a computer-controlled motion platform and a means of attaching various toolheads. These enable PopFab to make objects from a digital plan in a variety of ways: current capabilities include 3D printing (as you are about to see), milling, vinyl cutting, and drawing -- with more on the way."
