Invention Summary:

This invention uses digital light processing techniques for the direct 3D printing of ~10nm silica nanocages to form hierarchically porous parts with arbitrary shapes, tunable internal structures, and high porosity.

Technology Overview:

The convergence of 3D printing techniques and nanomaterials is generating a compelling opportunity space to create advanced materials with multiscale structural control and hierarchical functionalities. Researchers at Cornell University have developed a new class of photoresponsive functional inks by using functionalized intrinsically porous nano-sized silica nanocages, they developed a technique for the direct printing of mesoporous parts. The versatile functionalization of the silica cages allows control of the internal microstructure and chemical functionality of the as-printed structures or further steps allowing internal functionalization. This approach leverages prior nanomaterials research comprising a large variety of nanosized building blocks that offer a wide range of chemical and physical properties.




  • Enable complex 3D material designs not accessible through other techniques.

Potential Applications:

  • Functionalizing 3D printed objects for their use in sensing, catalytic, or energy device manufacturing
