1. A process of forming a cross-linked filament for a surgical device comprising:
- mixing first and second precursors, each of the first and second precursors possessing a polyol core and functionalized with at least one functional group having click reactivity when exposed to UV radiation, wherein the at least one functional group of the first precursor is a thiol group and the at least one functional group of the second precursor is an alkene group; and
extruding the first and second precursors through an extrusion unit to produce a filament,exposing the first and second precursors to UV radiation during the extruding process.

Abstract
Cross-linked fibers include first and second precursors, each possessing a core and at least one functional group known to have click reactivity when exposed to UV radiation. Mixtures of the first and second precursors are extruded to produce a filament and irradiated with UV light during the extrusion process.
