Title: Additive manufacture of electrically conductive materials

Abstract

A method of additive manufacturing includes depositing a layer of absorptive material onto a workpiece, depositing a layer of additive manufacturing stock powder onto the workpiece, and fusing the stock powder to the workpiece using a focused energy source at a wavelength wherein the absorptive material has a higher absorptivity at the wavelength of the focused energy source than the absorptivity of the stock powder at that wavelength. The focused energy source can be a laser, e.g., with a 1064 nm wavelength, for example.
