Abstract: An additive manufacturing system for producing a medical catheter or lead and a method thereof. The system including a heating cartridge defining an interior volume and at least one filament port. The system also including a heating element thermally coupled to the heating cartridge to heat the interior volume, a filament handling system to feed at least one filament through the at least one filament port, and a substrate handling system. The substrate handling system including a clamp to secure a portion of a substrate to be moved relative to the heating cartridge to apply a jacket to the substrate. In one or more embodiments, a subassembly is positioned on the substrate and has an electrode ring. The jacket printed to cover at least a portion of the subassembly and spaced apart from the electrode ring.
