Abstract
Methods and apparatus for fabricating high-resolution thin-layer metal patterns and 3D Metal structures are provided. The methods and apparatus operate via photo-(stereo)lithography at room temperature. The printed metal patterns, for example silver patterns, exhibit high electrical conductivity, comparable to or better than the conductivity of the silver printed by current laser sintering or thermal annealing at high temperature.
