摘要： An additive manufacturing system may include an extruder. The extruder may include a barrel having a bore. Additionally, the extruder may include an extruder screw at least partially received within the bore of the barrel. The additive manufacturing system also may include a gear pump fluidly coupled to the bore of the barrel. The extruder screw may extend at least partially into the gear pump.

摘要： A planetary roller extruder includes a housing with an internal housing toothing. A central spindle is disposed in the housing and has an external central spindle toothing. A plurality of planetary spindles are disposed about the central spindle and in the housing. Each of the planetary spindles has an external planetary spindle toothing configured to mesh with the internal housing toothing and the external central spindle toothing. A drive is configured to rotate the central spindle. The drive includes a drive journal connected to the central spindle to permit transmission of a driving force from the drive to the central spindle. The drive journal includes a bore. The bore has internal projections configured to engage with the external central spindle toothing to secure the central spindle to the drive journal by a screw-type connection.
