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.

Abstract: A debinder provides for debinding printed green parts in an additive manufacturing system. The debinder can include a storage chamber, a process chamber, a distill chamber, a waste chamber, and a condenser. The storage chamber stores a liquid solvent for debinding the green part. The process chamber debinds the green part using a volume of the liquid solvent transferred from the storage chamber. The distill chamber collects a solution drained from the process chamber and produces a solvent vapor from the solution. The condenser condenses the solvent vapor to the liquid solvent and transfer the liquid solvent to the storage chamber. The waste chamber collects a waste component of the solution.
