1. A method performed by a processor and comprising:
determining a porosity level of a porous section of a screen apparatus to be fabricated via an additive manufacturing process in which:
on a layer-by-layer basis, build material is deposited and then one or more print agents are selectively applied onto the build material; and
energy is applied to the build material to selectively fuse the build material together;
determining one or more respective patterns at which the one or more print agents are to be selectively applied to the build material to provide controlled thermal bleeding of the build material upon application of the energy such that the build material is partially fused together past where at least one of the one or more print agents are selectively applied to the build material to realize the determined porosity level; and
causing an additive manufacturing apparatus to additively manufacture the screen apparatus via the additive manufacturing process using the determined one or more respective patterns during the selective application of the one or more print agents.
