Abstract
A method includes 3D printing a mold body from polycarbonate to form a cavity surface and 3D printing a permanent hydrophobic structure of polycarbonate on the cavity surface. The hydrophobic structure comprises a plurality of regularly shaped protrusions extending from and spaced 0 mm to 1.5 mm apart on the cavity surface. The patterned protrusions impart permanent hydrophobicity to the mold cavity surface.
