摘要： The present invention may comprise processes, methods, and systems for powder processing aimed at and characterized in reduction of adsorbed gases, vapors, particulates, and moisture through high-temperature vacuum out-gassing by disintegrating the powder bulk or flow into separate particles. Heat may be transferred to powder particles in vacuum by multiple interactions during intimate contact with heated metal balls within a tube or other container.

摘要： Embodiments of the present invention relate to methods for preparing high optical density solutions of nanoparticle, such as nanoplates, silver nanoplates or silver platelet nanoparticles, and to the solutions and substrates prepared by the methods. The process can include the addition of stabilizing agents (e.g., chemical or biological agents bound or otherwise linked to the nanoparticle surface) that stabilize the nanoparticle before, during, and/or after concentration, thereby allowing for the production of a stable, high optical density solution of silver nanoplates. The process can also include increasing the concentration of silver nanoplates within the solution, and thus increasing the solution optical density.

摘要： A method of forming an article includes producing a base powder including a plurality of base particles. Each base particle includes an external surface and a first material. The method further includes removing one or more oxides from the external surface of each base particle to form a cleaned powder including a plurality of cleaned particles. Each cleaned particle includes a cleaned external surface made of the first material. The method further includes coating the cleaned external surface of each cleaned particle with a second material having a greater oxidation resistance than the first material to form a coated powder including a plurality of coated particles. Each coated particle includes an external layer including the second material that fully covers the cleaned external surface made of the first material. The method further includes forming the article using the coated powder.

摘要： The devices, systems, and methods of the present disclosure are directed to powder spreading and binder distribution techniques for consistent and rapid layer-by-layer fabrication of three-dimensional objects formed through binder jetting. For example, a powder may be spread to form a layer along a volume defined by a powder box, a binder may be deposited along the layer to form a layer of a three-dimensional object, and the direction of spreading the layer and depositing the binder may be in a first direction and in a second direction, different from the first direction, thus facilitating rapid formation of the three-dimensional object with each passage of the print carriage over the volume. Powder delivery, powder spreading, thermal energy delivery, and combinations thereof, may facilitate consistently achieving quality standards as the rate of fabrication of the three-dimensional object is increased.
