A method for making an expanded, and optionally multi-component and/or colored PTFE monofilament is disclosed. The method includes forming a first paste by mixing a PTFE powder with a hydrocarbon solvent； forming an extrusion preform by pressing the first paste into a form； curing the extrusion preform by exposing the extrusion preform to a first temperature for a first time duration； forming a green monofilament by extruding the first paste through a die； expanding the green monofilament by exposing the green monofilament to a second temperature for a second time duration, the second time duration occurring after the first time duration； stretching the green monofilament substantially along a longitudinal axis of the green monofilament, the stretching the green monofilament occurring after the expanding the green monofilament； and sintering the green monofilament after the stretching the green monofilament. The method may include doing all or some of the expanding, stretching and sintering steps simultaneously.
