摘要： 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.

摘要： 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.

摘要： Devices, systems, and methods are directed at spreading sequential layers of powder across a powder bed and applying energy to each layer to form a three-dimensional object. The powder can include granules including agglomerations of metallic particles to facilitate spreading the metallic particles in each layer. The energy can be directed to the powder to reflow the granules in each layer to bind the metallic particles in the layer to one another and to one or more adjacent layers to form the three-dimensional object. Thus, in general, the agglomeration of the metallic particles in the granules can overcome constraints associated with metallic particles that are of a size ordinarily unsuitable for flowing and/or a size that presents safety risks. By overcoming these constraints, the granules can improve formation of dense finished parts from a powder and can result in formation of unique microstructures in finished parts.

摘要： Techniques and compositions are disclosed for composite feedstocks with powder/binder systems suitable for three-dimensional printing, such as fused filament fabrication. The composite feedstocks may include a jacket about a core, with at least the core including a powder material suspended in a binder system and the jacket having a hardness or toughness greater than a hardness or toughness of the core for the feedstock. In general, the harder jacket may protect the core from unintended deformation or damage during transportation, storage, or use. For example, the difference in hardness or toughness between the jacket and the core may facilitate gripping the feedstock (e.g., by gear drives or the like) with a higher amount of force than is otherwise applicable if the feedstock were composed of the core alone, without damaging the core, during a fused filament fabrication process or another additive manufacturing process.

摘要： Devices, systems, and methods are directed to coated powder for three dimensional additive manufacturing. The powder may include a first material coated with a second material, with the coating advantageously resisting segregation of the first material and the second material during handling processes associated with fabrication. The reduced segregation of the first material and the second material may facilitate forming finished three-dimensional parts with improved homogeneity of microstructures and, thus, improved physicochemical properties. More generally, the reduced segregation of the first material and the second material achievable through coating the first material with the second material may facilitate binder jet fabrication using a wider array of combinations of first material and second material as compared to binder jet fabrication using mixtures of constituent powders of the first material and the second material.

摘要： Materials and methods are disclosed for forming interface layers between objects being 3D printed and their underlying support structures, as well as dissolvable supports. The materials and methods facilitate separation of the objects from the supports after all processing is completed and are particularly useful when 3D printing metal objects that have to be sintered subsequent to 3D printing.
