摘要： 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.

摘要： In an example method for forming three-dimensional (3D) printed electronic parts, a build material is applied. An electronic agent is selectively applied in a plurality of passes on a portion of the build material. A fusing agent is also selectively applied on the portion of the build material. The build material is exposed to radiation in a plurality of heating events. During at least one of the plurality of heating events, the portion of the build material in contact with the fusing agent fuses to form a region of a layer. The region of the layer exhibits an electronic property. An order of the plurality of passes, the selective application of the fusing agent, and the plurality of heating events is controlled to control a mechanical property of the layer and the electronic property of the region.
