1. A non-transitory computer-readable medium on which is stored machine-readable instructions that when executed by a processor, cause the processor to:
place a plurality of anchor points at determined locations of a digital model of an item to be fabricated by a three-dimensional (3D) fabrication system, wherein the anchor points comprise points that remain in place during a placement determination of pores in the digital model of the item, and wherein the anchor points correspond to locations at which pores are or are not to be formed in the digital model;
determine places at which the pores are to be set in the digital model of the item, wherein the pores are to be placed to comply with a predefined constraint with respect to each other and the anchor points; and
modify the digital model to place the pores at the determined places in the digital model and to add pores at anchor points that correspond to pores in the digital model.
