| Abstract Scope |
Active materials are increasingly gaining importance as actuators across the biomedical and aerospace industries among others. Multi-material additive manufacturing is promising for active element integration as it allows for bi-material interfaces without the need for welding as a postprocess. However, design and characterization of these interfaces is critical to fully incorporate functionality. In this study we explore filament-based materials extrusion as a tool for 4D multi-metal printing. This approach enables the tailored design of materials responses specific to applications through the selective coupling of active-active or active-structural metal combinations. We can achieve diverse mechanical responses within a single component by printing a shape memory alloy such as NiTi as the active element. For the combination of active and structural metals, single material filaments are utilized during the printing process and then co-sintered. To optimize interfaces, we compare local and bulk mechanical properties and correlate them to the phases present. |
