Abstract:
Disclosed herein are solution-based additive manufacturing inks comprising a polymer, a volatile solvent compound, and a nonsolvent compound. With current additive manufacturing techniques, a wide range of functionally innovative polymers are left without the ability to be used in additive manufacturing. Improved additive manufacturing techniques to process advanced functional polymers are desirable. The disclosed ink is operable to render any chosen polymer useable in additive manufacturing methods. The composition of the disclosed ink allows for a phase inversion to occur to transition the ink from a liquid ink to a solid manufactured structure. Also disclosed herein are devices for additive manufacturing of the ink and methods for making the same.
