摘要
Embodiments of the present disclosure are drawn to additive manufacturing apparatus and methods. An exemplary additive manufacturing system may include an extruder (61), the extruder having an opening (40) dimensioned to receive a material. The apparatus may also include an extruder output in fluid communication with the extruder, wherein the extruder output extends away from the extruder along a longitudinal axis. One or more heaters (41) positioned along at least a portion of the extruder output may also be included, and, as the material passes through the extruder output, the one or more heaters may at least partially melt the material. The system may also include a gear pump (74) in fluid communication with the extruder output for receiving the at least partially melted material, and a nozzle (51) in fluid communication with the gear pump for depositing the at least partially melted material.
