BINDER JETTING IN ADDITIVE MANUFACTURING OF INHOMOGENEOUS THREE-DIMENSIONAL PARTS
Last updated:
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.
