ABSTRACT:
A freeform fabrication system preferably includes low-density particles, a cationic polyelectrolyte component, an anionic polyelectrolyte component, and a polar solvent-based binder capable of stimulating a reaction between the cationic polyelectrolyte component and the anionic polyelectrolyte component to form a low-density particle-bound polyelectrolyte complex.
