3D Printed Inherently Porous Structures
3D printing is great for making complex polymer objects, but not for large structures with sub-micrometer features. However, porous sub-micrometer structures are important for various applications. We developed a method that combines 3D printing with polymerization-induced phase separation, allowing us to create digitally defined, macroscopic polymer structures with controllable sub-micrometer porosity. This could have implications for areas such as adsorption, separation, sensing, and drug delivery platforms.

Tailored Design For Your Needs
The process of 3D printing provides an immense degree of flexibility in fabricating polymer objects with intricate geometries. Our technology takes advantage of this capability to create personalized functional materials, which can be applied in a variety of fields, including metamaterials, sensors, drug delivery systems, microfluidics, and filtration.
