Abstract
According to one aspect, embodiments herein provide a furnace for debinding and sintering additively manufactured parts comprising a unitarily formed retort having at least one open side, a heater for heating a sintering volume within the retort to a debinding temperature and to a sintering temperature, an end cap sealing the at least one open side, a forming gas line penetrating the end cap for supplying forming gas at a flowrate, and a heat exchanger within the retort, outside the sintering volume, and adjacent a heated wall of the retort, the heat exchanger having an inlet connected to the forming gas line and an outlet to the sintering volume, wherein the heat exchanger includes a heat exchange tube length sufficient to heat the forming gas to within 20 degrees Celsius of the sintering temperature before the forming gas exits the outlet.
