1. A method of manufacturing an implantable mesh comprising the steps of:
determining a mesh layout having filament retention points;
providing a support surface with pins in a configuration that corresponds to the filament retention points;
feeding a biocompatible filament by a tensioner to a dispenser tip; and
translating the support surface with respect to the dispenser tip, wherein the support surface is translated in two dimensions independent from each other to wind the biocompatible filament around the pins to form an implantable macroporous mesh having a pore size based on the determined mesh layout.
