Most of use have probably had those moments when we wished that we had our 3D printer with us, but unfortunately it was back home, due to its large clunky size, and lack of portability. A couple guys have come up with a design for a truly portable and self-contained 3D printer that they hope can make a different in field work, field hospitals, and scientific research. The TOME is a printer that folds up into a briefcase, runs on battery power (solar chargeable), and is going to be very affordable ($1500 or less).
