    Abstract: Techniques for additive deposition are disclosed herein. In one embodiment, a method includes depositing a first portion of a precursor material onto a deposition platform, the precursor material including a suspension of nano-particles and forming a first solid structure of the nano-particles on the deposition platform from the deposited first layer of the precursor material. The method can also include depositing a second portion of the precursor material onto the formed first solid structure of the nano-particles and forming a second solid structure on the first solid structure from the deposited second layer of the precursor material. The three dimensional structure thus formed can be partly or fully cured or sintered during deposition or after deposition resulting in a controlled hierarchical porosity at multiple levels, from mesoscale (e.g., about 10 μm to about 250 μm) to nanoscale (e.g., about 900 nm or less) in the same structure.
