1. A method for creating a three-dimensional structure within a first material, the method comprising:
causing a phase change in a region of the first material by applying focused energy to the region using a focused energy source; and
displacing the first material in the region with a second material,
wherein the first material is a Herschel-Bulkley material having a yield stress less than 100 Pascals, and
wherein the first material comprises a soft granular gel made from polymeric packed micro-particles.
