20230227680 · 2023-07-20 · ·

Additive manufacturing processes, such as powder bed fusion of thermoplastic particulates, may be employed to form printed objects in a range of shapes. It is sometimes desirable to form conductive traces upon the surface of printed objects. Conductive traces and similar features may be introduced during additive manufacturing processes by incorporating a metal precursor in a thermoplastic printing composition, converting a portion of the metal precursor to discontinuous metal islands using laser irradiation, and performing electroless plating. Suitable printing compositions may comprise a plurality of thermoplastic particulates comprising a thermoplastic polymer, a metal precursor admixed with the thermoplastic polymer, and optionally a plurality of nanoparticles disposed upon an outer surface of each of the thermoplastic particulates, wherein the metal precursor is activatable to form metal islands upon exposure to laser irradiation. Melt emulsification may be used to form the thermoplastic particulates.

Reduced visibility conductive micro mesh touch sensor

A method for fabricating a metallic wire mesh touch sensor with reduced visibility. A metallic wire mesh is formed on a transparent substrate such that the surface of the metallic wires is roughened or textured, so as to cause high scattering of incident light, thereby minimizing specularly reflected light towards the user. The metal lines are formed over patterned catalytic photoresist. The rough or textured surface of the metallic wires is achieved by roughening or texturing the catalytic photoresist, by selecting parameters of electronless plating of copper, or both. An RMS surface roughness of about 50 nm would scatter approximately 70% of incident cyan light incident at 30°.
