Abstract: A powder bed material can include from 80 wt % to 100 wt % metal particles having a D50 particle size distribution value from 4 μm to 150 μm. From 10 wt % to 100 wt % of the metal particles can be surface-activated metal particles having in intact inner volume and an outer volume with structural defects. The structural defects can exhibit an average surface grain density of 50,000 to 5,000,000 per mm2.

Abstract: In an example 3D printing method, an electrical conductivity value for a resistor is identified. Based upon the identified electrical conductivity value, a predetermined amount of a conductive agent is selectively applied to at least a portion of a build material layer in order to introduce a predetermined volume percentage of a conductive material to the resistor. Based upon the identified electrical conductivity value and the predetermined volume percent of the conductive material, a predetermined amount of a resistive agent is selectively applied to the at least a portion of the build material layer in order to introduce a predetermined volume percentage of a resistive material to the resistor. The build material layer is exposed to electromagnetic radiation, whereby the at least the portion coalesces to form a layer of the resistor.
