  • Extrusion die and nozzle cooling system for large scale 3D additive manufacturing
    Patent number: 10807292
    Abstract: An additive manufacturing (AM) extrusion die system having an extrusion die configured to receive a material to be extruded. The extrusion die includes a main body having a cylindrical section and a distal tapered section terminating at an extruder tip. The main body is configured to mount to a barrel of an additive manufacturing system. The die further includes a central extruder channel extending axially along the main body configured to receive the material at the cylindrical section of the main body and output the material at the extruder tip of the main body, and a cartridge heater slot formed within the main body and generally parallel to the central extruder channel. The cartridge heater slot configured to receive a cartridge heater therein for imparting thermal energy to the material within the central extruder channel. A cooling system is provided for controlling a temperature of the material.
