MIT News reports that its researchers have worked closely with a team from the University of Texas at Austin to create a prototype 3D printer that is smaller than a coin. c Conceptual diagram of the proposed chip-based 3D printer, showing a hologram formed by a chip within a resin chamber (not to scale). The portability and speed of this palm-sized printer could allow anyone — engineers, doctors, or even first responders — to create solutions on the fly without needing to lug around a big and heavy device.
