Abstract
A functional polymeric cutting edge structure and methods for the manufacturing of cutting edge structures comprised of polymeric materials are provided. The cutting edge structures may be produced on a substrate having a blade body or blade support type. The polymeric material is produced by curing a precursor material activated by electromagnetic radiation wherein a wavelength of said radiation is about double a wavelength required to activate the precursor material. A razor blade for use in a razor cartridge or a blade box may be formed using the present invention.
Claims14
A method for manufacturing at least one cutting edge structure from a polymeric material comprising the steps of:
- (a) providing a computer model of a cutting edge structure;
- (b) providing a precursor material;
- wherein said precursor material is a liquid precursor disposed in a container in step (b) and prior to step (c), a step of converting said liquid precursor material to a solid precursor material;
- (c) activating portions of said precursor material in a focal point of electromagnetic radiation while at least one substrate is disposed in said precursor material, wherein a wavelength of said radiation is about double a wavelength required to activate said precursor material;
- (d) moving the focal point of said radiation within said precursor material to form at least one cutting edge structure on said substrate based on said model;
- and
- (e) curing portions of said activated precursor material to produce said cutting edge structure comprised of a polymeric material, wherein said at least one cutting edge structure is a razor blade or a portion of a blade box.
