3D printing of Nanofibers has enabled power dense batteries, military wearables, chemical and biological defence

A nanofiber is a fiber with a diameter of 100 nanometers or less. The nanofibers due to some special properties  are being investigated for a myriad of potential applications in the fields of medicine, electronics and other material sciences. Such fibers have a high ratio of surface area to volume. This makes them particularly useful for solar cells, which try to maximize exposure to sunlight. In addition, nanofibers yield materials that are permeable at the small scale, which makes them suited for use as water filters. The fibers, when bound, are also relatively strong.
