Abstract: Some examples include an additive manufacturing method for controlling electrostatic discharge of a build object. The method includes receiving data related to a build object, the data including conductivity data, selectively depositing a first portion of a printing agent onto a build material layer in a pattern of an object layer of a build object, the printing agent being electrically conductive at a predetermined dosage, the first portion deposited at less than the predetermined dosage, selectively depositing a second portion of the printing agent onto the build material layer at an area of the pattern, the printing agent at the area deposited at or above the predetermined dosage, and applying fusing energy to form the object layer, the object layer of the build object including a shell formed at the area and a core, the shell being electrically conductive and the core being electrically non-conductive.

Abstract: Some examples include an additive manufacturing build object including an electrical component and a build object body. The electrical component having a varying electrical resistivity within a resistivity range of 109 ohms per square to 105 ohms per square, the resistivity range obtained by an application and fusing of a fusing component of a printing agent and build material, the printing agent applied to the build material at a predetermined saturation dosage range corresponding to the resistivity range. The build object body having a second electrical resistivity obtained by an application and fusing of the fusing component of the printing agent and the build material, the printing agent applied at a dosage below the predetermined saturation dosage range, the build object body being electrically non-conductive.
