Solution-based system for printing a 3D structure

A solution-based system for printing a 3D structure, comprising:

• a substrate;
• a first solution comprising 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, wherein the first solution is configured to be applied to a surface of the substrate, and wherein the first solution is configured to form the first SAM including a first SAM surface as a basis for the 3D structure when the first solution is applied to the surface of the substrate;
• a second solution comprising metal ions, wherein the substrate with the first SAM is immersed into the second solution, wherein the first solution is configured to be applied to the substrate which is immersed in the second solution, and wherein the first solution is configured to obtain molecular-metal SAMs to provide a multiple layered SAM material when the first solution is applied to the substrate which is immersed in the second solution;
• and
• means for applying a force and forming the 3D structure from the multiple layered SAM material, wherein the 3D structure is provided on the substrate.
