| Abstract Scope |
We have developed droplet and filamentary 3D printing methods for patterning dense and porous 3D architectures. To facilitate their rapid design and assembly, we have engineered the composition and rheological behavior of concentrated inks and matrix materials composed of soft building blocks, including colloidal particles, hydrogels, and even living cells. We have also designed and implemented novel printheads that enable active mixing and switching between different materials “on-the-fly” during printing. Several examples from our research will be highlighted. |
