Catalyst ink for three-dimensional conductive constructs

Abstract:

A method of constructing conductive material in arbitrary three-dimensional (3D) geometries, such as 3D printing. The method may include selective application of an aerosol-based colloidal solution containing a catalytic palladium nanoparticle material onto a substrate and then immersion of the coated substrate into an electro-less plating bath for deposition of conductive copper material. The above steps may be repeated to create arbitrary 3D geometric constructs containing conductive metallic patterns.
