Abstract: Powder—based additive manufacturing processes for producing integral parts with multiple metallic materials are disclosed. The integral parts are printed as single pieces by joining different metallic materials together during printing. A combination of different powder-based additive manufacturing processes or the same process can be used to produce the integral part.

Abstract: Processes for tailoring the macroscopic shape, metallic composition, mechanical properties, and pore structure of nanoporous metal foams prepared through combustion synthesis via direct write 3D printing of metal energetic ligand precursor inks made with water and an organic thickening agent are disclosed. Such processes enable production of never before obtainable metal structures with hierarchical porosity, tailorable from the millimeter size regime to the nanometer size regime. Structures produced by these processes have numerous applications including, but not limited to, catalysts, heat exchangers, low density structural materials, biomedical implants, hydrogen storage medium, fuel cells, and batteries.

Abstract: The present invention is directed towards a method for fabricating a three-dimensional metal, ceramic, and/or cermet part, the method comprising forming the three-dimensional metal, ceramic, and/or cermet part by an additive manufacturing technique; encapsulating the three-dimensional metal, ceramic, and/or cermet part in a conformable fugitive material to form an encapsulated three-dimensional metal, ceramic, and/or cermet part; and cold isostatic pressing the encapsulated three-dimensional metal, ceramic, and/or cermet part with pressurized incompressible fluid that contacts the conformable fugitive material. Also disclosed are three-dimensional metal, ceramic, and/or cermet parts fabricated according to said method.

Abstract: A system and method are described for post-processing a 3D printed component. For example, support structures for the 3D printed component may be removed during post-processing. In the system and method, a first image of a component is stored in memory. A second image of a 3D printed component corresponding to the component is also captured. One or more cutting paths between the 3D printed component and the support structures is then determined based on the first image and the second image. The 3D printed component may then be autonomously separated from the support structures by cutting through the cutting path.
