Quick reminder: the modular smartphone is a real thing that's really happening. Motorola blew our minds with the announcement of a plan to create modular phones not totally unlike the Phonebloks concept, and now the manufacturer is one step closer to making some real hardware. 3D Systems, makers of the Cube 3D printer and similar equipment, is Motorola's first partner on the Project Ara.
So what does that mean? Motorola needs some way of adding flexibility to a traditionally rigid manufacturing process, and 3D printing would seem to be a natural solution.
