According to examples, an apparatus may include a memory on which is stored instructions that when executed by a processor, cause the processor to access a digital file identifying a first plurality of parts to be fabricated in a first level of a build volume in a three-dimensional (3D) fabrication operation and a second plurality of parts to be fabricated in a second level of the build volume. The processor may also determine a first usage of a plurality of nozzles corresponding to fabrication of the first plurality of parts in the first level of the build volume and determine a modification to a property of the second plurality of parts to be fabricated in the second level of the build volume to have a second usage of the plurality of nozzles that differs from the first usage.

Modify property of 3D parts to cause different nozzle usages

In some examples, a fluid system includes a support structure to attach a fluid dispensing device comprising a fluid chamber to contain a fluid, and an orifice to dispense the fluid from the fluid chamber. The fluid system includes a circulation path comprising a path portion in the fluid dispensing device, the circulation path to circulate a fluid flow through the fluid chamber to remove, from the fluid chamber, a particle ingested through the orifice. A filter in the circulation path is to remove the particle from the circulation path.
