Sumario:Additive manufacturing (AM) has transformed the way we can design and produce components at the macroscale level. AM has enabled the fabrication of innovative products with specific geometries that are not accessible by traditional manufacturing techniques. Microscale AM holds a great potential in a broad range of scientific applications. However the downscaling of additive techniques to the micro- and nanoscale is still in state of art when it comes to metal printing. The exploration of the new submicrometric AM comprises the multi-material capabilities. The extension of the chemical control composition to the metal AM has been found to be a strongly promising field of analysis as several applications and techniques are arising. Herein, a microscale multi-metal AM technique based on the meniscus-confined electrodeposition (MCED) is introduced. This multi-metal novel technique enables the direct printing of individual and mixing of multiple metals from a single multichannel nozzle. Multi-metal MCED combines the high spatial resolution of MCED printing, with the in situ straight-forward deposition of metal ions from metal salt solutions. This technique unlocks a simple way to 3D print multi-metal structures with pre-defined local properties and opens new pathways for the direct fabrication of materials and devices with unique chemical architectures. Moreover, a study of several feasible substrate materials for MCED and a system for printed features damage-free release from the substrate are elaborated. The releasing methodology enables the confinement of the structures in a reduced area for continuous visual tracking
