A direct-write nanomanufacturing technique is developed for the high-speed, continuous fabrication of micro- and nano-fibers made of soluble ionic solids in a low-humidity ambient environment. The process is based on the fast evaporation of solvent and the precipitation of solute in the nanoscale meniscus. Freestanding nanofibers, suspended or stacked nanofiber arrays, and even a continuously wound microfiber roll with a fiber length over 40 cm are fabricated.
