according to google, the newest update to the modular handset will use dye-sublimation for its module production rather than 3D printing them. the interchangeable units are instead expected to be made of injection-molded polycarbonate plastic which will then be able to be customized at high resolution and in full color. following the announcement of ‘spiral 2’, a test pilot program in puerto rico will begin later this year with a global launch to come later in 2015.
