| Abstract Scope |
The control of microstructure is one of the most critical challenges facing microscale additive manufacturing (µ-AM) of metals. It is necessary to gain control over the microstructure, and hence mechanical and electrical properties of printed structures for various functional applications. In this presentation, we demonstrate that the microstructure of the microscale 3D-printed metal using the localized pulsed electrodeposition (L-PED) process can be engineered via control over the process parameters. Results show that the density and the orientation of the twin boundaries, and the grain size can be controlled through electrochemical process parameters. Additionally, we employed in situ SEM nanomechanical experiments to directly correlate the microstructure-property relationship. This important advancement eliminates the need for post-processing to engineer the microstructure, which often has undesirable consequences for material properties. The new capability enables control of spatial mechanical and electrical properties of the 3D-printed metal during the process. |
