1. An apparatus comprising:
a processor; and
a memory storing instructions executable by the processor to:
access a digital file identifying a first plurality of parts and a second plurality of parts to be additively fabricated in a build volume by, on a layer-by-layer basis, depositing a layer of build material powder, selectively ejecting print agent on the deposited layer by a plurality of nozzles, and fusing the build material powder in accordance with where the print agent was selectively ejected by the plurality of nozzles;
determine a first usage of the plurality of nozzles to selectively eject the print agent to additively fabricate the first plurality of parts in a first level of the build volume; and
determine a modification of either or both of an orientation and a position of the second plurality of parts to be fabricated in a second level of the build volume above the first level, such that a second usage of the plurality of nozzles to selectively eject the print agent to additively fabricate the second plurality of parts in the second level differs from the first usage in a way that increases uniformity in nozzle usage in print agent ejection.
