1. A method of additively manufacturing a composite object, comprising:
providing a supply of polymer to a dispensing device;
providing continuous fibers pre-pregged with polymer to the dispensing device;
heating the supply of polymer inside the dispensing device;
dispensing the heated supply of polymer out of the dispensing device through a first opening of the dispensing device;
dispensing the pre-pregged continuous fibers out of the dispensing device through a second opening of the dispensing device against the supply of thermoplastic previously dispensed out of the dispensing device; and
moving the dispensing device during dispensing through the first and second openings to form the composite object.
