1. A method, comprising:
acquiring a three-dimensional printed template created using an additive manufacturing technique, wherein lengths of at least some continuous portions of the template extend an entire length of the template;
infilling the template with an aerogel precursor solution;
allowing formation of a sol-gel; and
converting the sol-gel to an aerogel.
