Abstract: Additive manufacturing (AM) can be used to fabricate a wide palette of interlocking metasurfaces (ILMs). ILMs can be architecturally tailored to achieve intentional engagement and disengagement forces, and are amenable to topological optimization. ILMs can be fabricated using nearly any AM process at different length scales according to the capabilities of the process. As a result, ILMs represent a new class of joining technology enabled by additive manufacturing that is complementary to traditional joining processes including fasteners, welds, adhesives, etc.

Abstract: The present invention relates to treating a test sample using electropulsing. In particular, the test sample includes an additively manufactured material. Such electropulsing can provide enhanced properties, such as modified material properties such as improved ductility.
