The synergistic integration of nanomaterials with 3D printing can create architecture and devices with an unprecedented level of functional integration. However, the inability to selectively anneal printed materials on a broad range of temperature-sensitive constructs has limited the potential functional complexity and performance. Prior works primarily rely on heating the entire printed object post-printing in a bulk annealing process, which severely limits the possible materials integration and geometrical configuration. Alternatively, highly focused electromagnetic waves are attractive strategies that can achieve in situ localized heating of printed material to program its mechanical and electrical properties. Here, we demonstrate the ability to selectively and locally anneal 3D printed nanomaterials in situ on a broad range of temperature-sensitive substrates by exploiting metamaterials-inspired electromagnetic structures. We demonstrate the ability to create spatially freeform microstructure where the electronics and mechanical properties can be locally programmed, significantly broaden the materials compatible with a 3D printing process.
