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.
Claims7
A method, comprising:
- manufacturing a mold body having a cavity surface;
- and
- creating a permanent hydrophobic structure on the cavity surface, wherein the mold body and the hydrophobic structure are 3D printed, wherein the mold body or the hydrophobic structure are made of polycarbonate, wherein the hydrophobic structure comprises a plurality of regularly shaped protrusions, and wherein each protrusion is spaced from an adjacent protrusion at a distance of 0 mm to 1.5 mm.
