Abstract: A furnace system for printing an object using additive manufacturing. The furnace system may include a furnace chamber; an outlet fluidly coupled to the furnace chamber for removal of an exhaust gas from the furnace chamber; a conduit fluidly coupled to the outlet; an oxygen injector fluidly coupled to the conduit; an isolation system fluidly coupled to the conduit between the furnace chamber and the oxygen injector; and a catalyst enclosure comprising an oxidizing catalyst.

Abstract: A materials processing furnace provides for debinding and sintering objects and treating effluent generated by the sintering. A heating chamber maintains a controlled atmosphere for sintering the object. A vacuum pump evacuates an effluent from the heating chamber, and an injector adds a reagent to the evacuated effluent to form a mixed gas. A catalytic converter receives the mixed gas and catalyzes one or more hazardous or offensive compounds of the effluent, thereby converting the effluent to a safer and less offensive exhaust. As a result, the furnace is suitable for operation in an office environment.
