[Abstract]
Three-dimensional (3D) printing, also known as additive manufacturing, is widely regarded as a revolution in manufacturing technology, with significant promise for electronic and biomedical applications; this field is known as 3D printed electronics. However, it is difficult to obtain functional 3D structures for electronics, although we can easily produce plastic or metallic 3D objects with coarse resolution via various commercial 3D printing methods, such as stereolithography (SLA), fused deposition modeling (FDM), or selective laser sintering (SLS). Finding the appropriate printing approach for the achievement of functional 3D structures with high spatial resolution remains one of the major challenges in the field of 3D printed electronics.
Here, we demonstrate a novel strategy for multiple-materials 3D printing at room temperature in ambient air conditions. Our strategy includes development of 3D printable functional materials, 3D printing process and 3D printing tools. The 3D micro- and nanoarchitectures are printed by an omnidirectional accurate control of a micro-nozzle filled with functional inks. A simple modulation of the ink leads to 3D printing for multiple-materials, such as graphene, carbon nanotube (CNT), metal oxide, metal, magnet, and their composite. Successful demonstrations of 3D printed functional components are also described herein. We believe that this approach paves the way for efficient multi-material 3D printing with high spatial resolution, which will ultimately lead to important advancements in 3D printed electronics.
