Abstract
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.
Claims20
An additive manufacturing system comprising:
- an extruder, including:
- a barrel including a bore;
- and
- an extruder screw at least partially received within the bore of the barrel;
- and
- a gear pump fluidly coupled to the bore of the barrel, the gear pump including an outlet opening including a narrowed portion axially aligned with the gear pump and extending within the gear pump;
- wherein the extruder screw extends beyond the barrel and at least partially into an inlet opening of the gear pump such that an end of the extruder screw is spaced apart from rotating components of the gear pump.
