Abstract: Apparatus and methods for debinding articles. The apparatus and methods may transform binder from furnace exhaust before the exhaust is discharged to the atmosphere. The apparatus may include a furnace retort and a reactor. The furnace retort may be configured to: exclude ambient air; and receive a carrier gas. The reactor may be configured to: receive from the retort (a) the carrier gas and (b) material removed in the retort from the article; and combust, at a temperature no greater than 750° C., the material. The material may be decomposed binder. The material may be hydrocarbon from binder that is pyrolyzed in the retort. The carrier gas may include gas that is nonflammable gas.

Abstract: A three dimensional printer incorporates a kinematic coupling between the build platform and movable stage which holds the build platform, of three curved protrusions attached to one of the build platform or the movable stage and six locating features formed in receivers of the other. At least two flexures differentially change a Z position of each of two of the curved protrusions. 3D printing is paused at a preset level of completion, and the build platform may be removed for external operations. A print resume circuit resumes printing of additional printed layers at the previous position in response to a return detection circuit that responds to an input (e.g., a touch screen confirmation).
