1. A solution-based method for printing a 3D structure, comprising:
providing a substrate;
providing a first solution including an organic molecule including a functional group at each end for creation of self-assembled monolayers (SAMs) including a first self-assembled monolayer (SAM) as a building block for printing the 3D structure;
applying the first solution to a surface of the substrate to form the first SAM including a first SAM surface as a basis for the 3D structure;
providing a second solution including metal ions;
immersing the substrate with the first SAM into the second solution;
injecting the first solution to the substrate which is immersed in the second solution thereby obtaining molecular-metal SAMs to provide a multiple layered SAM material; and
applying a force and forming the 3D structure from the multiple layered SAM material, wherein the 3D structure is provided on the substrate.
