1. An apparatus comprising:
a processor; and
a memory on which are stored machine-readable instructions that when executed by the processor, cause the processor to:
cause formation of a build layer of a three-dimensional (3D) object, including:
depositing and spreading a layer of build material particles; and
selectively applying print agent on the layer in order to realize the build layer of the 3D object;
determine physical characteristics of the formed build layer at a plurality of locations of the build layer;
determine, based on the physical characteristics determined at the locations of the build layer, dosing adjustments to the print agent be used when forming a subsequent build layer of the 3D object, the dosing adjustments being other than systemic adjustments for the subsequent build layer as a whole, the dosing adjustments being local adjustments for certain locations of the subsequent build layer; and
cause formation of the subsequent layer of the 3D object, including:
depositing and spreading a subsequent layer of build material particles; and
selectively applying the print agent on the subsequent layer in accordance with the dosing adjustments to the print agent to realize the subsequent build layer of the 3D object.
