Various implementations include a fused filament fabrication print head system that includes a nozzle, a heating block, and a cooling element. The nozzle defines a nozzle opening and a filament flow path and is configured to deposit a filament through the nozzle opening. The heating block is coupled to the nozzle such that the filament flow path extends through the heating block. The heating block includes a heating element. The cooling element is spaced apart from the heating block along the filament flow path and is configured to provide localized cooling to a portion of the filament at a location along the filament flow path prior to the heating block. The localized cooling provided by the cooling element preserves the stiffness of the filament and ensures sufficient back pressure to push the filament through the heating block and nozzle opening.
