Abstract: A system for generating a user-adjustable furnace profile, comprises a user interface configured to receive one or more materials properties from a user, a processor, and a memory with computer code instructions stored thereon. The memory is operatively coupled to the processor such that, when executed by the processor, the computer code instructions cause the system to implement communicating with a furnace to ascertain one or more thermal processes associated with the furnace, identifying one or more object characteristics associated with an object to be processed by furnace, and determining a thermal processing parameter profile of at least one thermal processing parameter corresponding to each of the thermal processes, based on (i) the one or more part characteristics and (ii) the one or more materials properties, the thermal processing parameter profile characterizing a cycle of the one or more thermal processes.

Abstract: Devices, systems, and methods are directed to binder jetting for forming three-dimensional parts having controlled, macroscopically inhomogeneous material composition. In general, a binder may be delivered to each layer of a plurality of layers of a powder of inorganic particles. An active component may be introduced, in a spatially controlled distribution, to at least one of the plurality of layers such that the binder, the powder of inorganic particles, and the active component, in combination, form an object. The object may be thermally processed into a three-dimensional part having a gradient of one or more physicochemical properties of a material at least partially formed from thermally processing the inorganic particles and the active component of the object.

Abstract: Devices, systems, and methods are directed to the use of nanoparticles for improving fabrication of three-dimensional objects formed through layer-by-layer delivery of an ink onto a powder of metal particles in a powder bed. More specifically, the ink may include metal nanoparticles suspended in a non-oxidizing aqueous solution to facilitate maintaining the metal nanoparticles in a stable form, providing a shelf-life suitable for transportation and storage of the ink in large-scale commercial operations. The ink may be delivered onto the powder of the metal particles in the powder bed, where the nanoparticles may interact with the metal particles to improve strength of the three-dimensional objects being fabricated. Also, or instead, the nanoparticles may reduce the likelihood of defects associated with subsequent processing of the three-dimensional objects (e.g., slumping and shrinking and/or inadequate densification of the final part).

Abstract: A variety of additive manufacturing techniques can be adapted to fabricate a substantially net shape object from a computerized model using materials that can be debound and sintered into a fully dense metallic part or the like. However, during sintering, the net shape will shrink as binder escapes and the base material fuses into a dense final part. If the foundation beneath the object does not shrink in a corresponding fashion, the resulting stresses throughout the object can lead to fracturing, warping or other physical damage to the object resulting in a failed fabrication. To address this issue, a variety of techniques are disclosed for substrates and build plates that contract in a manner complementary to the object during debinding and sintering.

Abstract: Techniques for debinding additively fabricated parts are described that do not require solvent debinding or catalytic debinding, and that may be performed using only thermal debinding in a furnace. As a result, in at least some cases debinding and sintering may take place sequentially within a single furnace. In some embodiments, the techniques may utilize particular materials as binders that allow for a thermal debinding process that does not negatively affect the parts.

Abstract: A method of maintaining part geometry fidelity during infiltration of a metallic preform. The preform and an infiltration barrier are formed, either independently or together during an additive manufacturing process. The infiltration barrier prevents infiltrant from bleeding out from the preform where it is present, thus protecting fine geometries that would otherwise be filled with infiltrant.
