Novel inks for direct writing in three dimensions

Research output: Chapter in Book/Report/Conference proceedingConference contribution


Direct-write assembly of 3-D periodic structures requires control over, and, hence, a fundamental understanding of their phase behavior, structure, and rheology of concentrated inks. This talk will feature examples from our recent efforts in engineering novel inks from colloidal, nanoparticle, and polyelectrolyte building blocks. First, the design of concentrated nanoparticle inks with viscoelastic properties suitable for writing 3-D periodic structures with minimum feature sizes as low as 10 μm is described. Second, a new ink design based on concentrated polyelectrolyte complexes is highlighted that enables the fabrication of 3-D micro-periodic structures with submicron features. The myriad of 3-D inks and assembly routes under development offers the potential to architect complex structures required for structural and functional composites, tissue engineering scaffolds, microfluidic networks, as well as photonic band gap materials.
