Abstract
A method for forming parts with electrically conductive features includes applying a layer of thermoplastic polymer powder particles in a powder bed and selectively applying an aqueous pretreat composition including a metal chloride salt on a portion of the layer. A conductive fusing ink including transition metal particles and a dispersing agent is selectively applied onto the applied aqueous pretreat composition on the portion of the layer, wherein the dispersing agent binds to, and passivates surfaces of the transition metal particles. The layer is exposed to electromagnetic radiation to fuse the thermoplastic polymer powder particles in the portion of the layer and sinter the transition metal particles, thereby forming a conductive feature.
