| Abstract Scope |
Energy consumption is a key concern for in-space manufacturing due to challenges associated with heat generation and dissipation in the space environment. Contemporary metal additive manufacturing techniques, such as selective laser sintering (SLS) and electron beam melting(EBM), rely on high-temperature melting and rapid solidification of metal powders, consuming significant thermal energy. The energy inefficiency and incompatibility with microgravity conditions severely limit their applicability to in-space manufacturing. In this work, we demonstrate a novel metal shaping and joining technique that eliminates the need for melting. This technique leverages the principle of solid-state acoustic softening, in which ultrasonic energy induces localized lattice mobility and facilitates atomic diffusion across metal interfaces, thus yielding solid-state metallurgical bonding. This process is highly energy efficient, requiring less than 300W of power, and is gravity-independent due to the design of the process and material used. This makes it an excellent candidate for in-space 3D printing applications. |
