Abstract: A method for manufacturing shaped polymers of surface-active macromolecules, in particular silk, is provided. The method is comprising the steps of: • a) depositing an aqueous solution of the surface-active macromolecules on a surface, wherein the aqueous solution of the surface-active macromolecules is deposited in the form of a droplet, and wherein the surface is a hydrophobic micropatterned surface adapted to prevent the aqueous solution from penetrating into the pattern and to receive the droplet of the aqueous solution of the surface-active macromolecules and retain its droplet state; and • b) forming shaped polymers of the surface-active macromolecules on the surface.
