Abstract
Illustrative examples of forming and using suitably adapted material in an additive manufacturing process includes operations of: exposing a first polymer sheet to a first plasma, such that an amine-functionalized sheet surface is formed; exposing a second polymer sheet to a second plasma, such that an epoxide-functionalized sheet surface is formed; and combining the amine-functionalized sheet and the epoxide-functionalized sheet, such that the amine-functionalized sheet surface contacts the epoxide-functionalized sheet surface. The workpiece is subsequently heated to form a structure, where heating of the workpiece causes covalent chemical bonds to form between the plasma-treated first polymer sheet and the plasma-treaded second polymer sheet.
