1. An aerogel, comprising:
a three-dimensional printed structure having printed ligaments geometrically arranged,
wherein an average diameter of the printed ligaments is in a range of greater than 0 microns and less than 50 microns,
wherein an average distance between a center of a first of the printed ligaments and a center of a second of the printed ligaments is at least equal to the average diameter of the printed ligaments, wherein the first and the second of the printed ligaments are adjacent,
wherein each printed ligament is comprised of a plurality of random pores, wherein an average diameter of the random pores is less than 50 nanometers,
wherein an average diameter of the random pores located on a surface of the printed ligaments is substantially equal to an average diameter of random pores located throughout an inside area of each of the printed ligaments, wherein the inside area is located between each surface of each of the printed ligaments.
