The invention generally relates to polymerizable conductive ink formulations comprising at least one metal source, at least one monomer and/or oligomer and a polymerization initiator, and uses thereof for printing three-dimensional functional structures. In particular a method of fabricating a three-dimensional conductive pattern on a substrate is disclosed, the method comprising: a) forming a pattern on a surface region of a substrate by using an ink comprising at least one metal source, at least one liquid polymerizable monomer and/or oligomer, and at least one polymerization initiator; b) polymerizing at least a portion of said liquid monomer and/or oligomer; c) rendering the metal source a continuous percolation path for electrical conductivity (sintering); d) repeating steps (a), (b) and optionally (c) to obtain a three- dimensional conductive pattern. |
