A method of creating a functionally-graded multi-material (FGM) part in multi-material additive manufacturing includes providing a part digitized into voxels, generating a lattice structure having a series of repeating unit cells, where each is the smallest nonrepeating constituent of the lattice structure and is generated by a continuous surface defined by a continuous function. The method further includes taking an inverse volume of the lattice structure within the part, creating a material gradient by varying a thickness of the surface at the boundary between the lattice structure and the inverse volume, assigning one of the two FGM component materials to the voxels in the volume occupied by the lattice structure and assigning the other to the voxels occupied by the inverse volume, outputting the voxels each with a designated material, the lattice structure and the inverse volume forming a mechanical interlock at the interface of the two component materials.

Embodiments relate to polycrystalline diamond compacts (“PDCs”) including a polycrystalline diamond (“PCD”) table in which a metal-solvent catalyst is alloyed with at least one alloying element to improve thermal stability of the PCD table. In an embodiment, a PDC includes a substrate and a PCD table bonded to the substrate. The PCD table includes diamond grains defining interstitial regions. The PCD table includes an alloy comprising at least one Group VIII metal and at least one metallic alloying element that lowers a temperature at which melting of the at least one Group VIII metal begins. The alloy includes one or more solid solution phases comprising the at least one Group VIII metal and the at least one metallic alloying element and one or more intermediate compounds comprising the at least one Group VIII metal and the at least one metallic alloying element.

A toothed transmission element includes a partial region formed with a first material, teeth defining an edge region which is formed additively with a second material having a hardness which is greater than a hardness of the first material, and a third material located between the first material and the second material, wherein a hardness decreases stepwise along a section leading from the edge region to the partial region.

According to aspects of the embodiments, there is provided method and system of using a roller-based deposition process to place two or more powders at some level of precision to build a multi-material, functionally-graded part. Instead of formulating a liquid ink by dispersing the powder feedstocks (metal or ceramic) in some binder-solvent mixture, there is detailed the use of two different types of fluid deposited in a digital manner on the roller surface. The two different types of fluids create a “wetted pixel” that can then capture a specific powder type with an affinity only to that fluid. Alternatives such as electrostatics, electrophotography, and the like are also provided to be used exclusively or with fluids to create an affine pixel to a particular powder type.

Systems and methods of additively manufacturing multi-material electromagnetic shields are described. Additive manufacturing processes use co-deposition to incorporate multiple materials and/or microstructures selected to achieve specified shield magnetic properties. Geometrically complex shields can be manufactured with alternating shielding materials optimized for the end use application. The microstructures of the printed shields can be tuned by optimizing the print parameters.
