Abstract
An ink includes a thermoplastic polymer and a solvent selected to melt the thermoplastic polymer. A method includes forming a three-dimensional (3D) structure using an ink, the ink includes a thermoplastic polymer and a solvent selected to melt the thermoplastic polymer. The method includes removing the solvent from the 3D structure, where the thermoplastic polymer remains substantially in the shape of the formed 3D structure after removal of the solvent.
