1. A non-transitory computer-readable medium on which is stored machine-readable instructions that when executed by a processor, cause the processor to:
obtain a digital model of a transfer screen to be fabricated by a three-dimensional (3D) fabrication system;
determine placements of a plurality of pores in the digital model of the transfer screen, wherein the transfer screen is to be mounted on a transfer mold via an attachment mechanism and to engage a surface of a wet part formed on a corresponding forming screen, wherein the forming screen has a first shape and the transfer screen has a second shape that is complementary to the first shape, and wherein the placements of the plurality of pores are determined to allow liquid to be suctioned from the wet part when a vacuum pressure is applied to the transfer mold; and
modify the digital model of the transfer screen to include the plurality of pores at the determined placements.
