Abstract
A method for forming a preform for a thermoplastic retention device is provided. The method includes providing a thermoplastic base material and blending the base material with one or more chemical agents to form a polymer blend. The chemical agents are configured to modify a polymer chain of the base material when the polymer blend is exposed to radiation. The method further includes forming the polymer blend into a filament sized for a three-dimensional printing platform and printing a preform shape from the filament using the three-dimensional printing platform. After the printed preform is hardened, the method includes exposing the printed preform shape to radiation sufficient to cause a reaction between the one or more chemical agents and the base material.
