description An apparatus suitable for extruding curable polymers for forming elastomer articles using additive manufacturing, and curable fluorine-containing polymer compositions suitable for use in such an apparatus are disclosed along with an additive manufacturing method for forming a fluorine-containing elastomer including providing a curable fluoropolymer composition, comprising at least one curable fluoropolymer; providing an additive manufacturing printer apparatus comprising a ram material extruder, wherein the ram material extruder comprises a ram device operable for extrusion under pressure and a printer nozzle; introducing the curable fluoropolymer composition to the ram material extruder; applying heat to the ram device, including the printer nozzle thereof; and applying pressure to the ram device to extrude the curable fluoropolymer composition; and printing, using the additive manufacturing printer apparatus, at least one layer of the extruded curable fluoropolymer composition exiting from an outlet of the printer nozzle onto a substrate to form the fluorine-containing elastomer article.
