In summary, a TPP-compatible, homogenous composite resin with high MWNT concentrations has been developed. Various functional 3D micro/nanostructures using the composite resins have been successfully developed via the TPP lithography. Precise MWNT assembly of ~100 nm spatial resolution has been achieved by the combination of TPP lithography and thermal pyrolysis. The composites demonstrated to have increased mechanical strength and enhanced electrical conductivity. 3D printing of micro/nanostructures using highly conductive MWNT-based composites paves the way toward arbitrary precise assembly of MWNTs, which is promising for a broad range of device applications such as 3D electronics and MEMS/NEMS.
