Abstract
Method for manufacturing a horology component, including manufacturing (E1) a first structure (10) from a first photosensitive resin (31) having at least one layer of photosensitive resin having a first pattern obtained by polymerizing the first photosensitive resin by irradiation through at least one mask (4), then developing the first photosensitive resin; and transforming (E2) the first structure (10) into a second structure (1) by structuring at least one surface of the first structure by the addition of a second photosensitive resin (32) to the at least one surface, the second structure (1) being intended to at least partially form a manufacturing mold for the horology component.
Claims20
A method for manufacturing a horology component, wherein the method comprises:
- manufacturing a first structure from a first photosensitive resin comprising at least one layer of photosensitive resin comprising a first pattern obtained by polymerizing the first photosensitive resin by irradiation through at least one mask, then developing said first photosensitive resin;
- and
- transforming the first structure into a second structure by structuring at least one surface of the first structure by the addition of a second photosensitive resin to the at least one surface, the second structure being intended to at least partially form a manufacturing mold for the horology component,
- wherein the transforming comprises:
- (i) applying a layer of the second photosensitive resin on at least part of the at least one surface of the first structure;
- (ii) performing two-photon polymerization on the second photosensitive resin in order to obtain three-dimensional polymerization according to a second pattern, using a photon device which comprises an objective which is at least partially immersed in the second resin to direct and focus a beam on voxels that define a shape or a geometry of the second pattern;
- and
- (ii) developing in order to eliminate the non-polymerized second photosensitive resin and obtain the second structure of a form defined by the first and second patterns.
A horology component comprising a structured surface,
- wherein the structured surface is integral with the rest of the horology component, and
- wherein the structured surface extends at least partially in a recessed manner over a lateral surface of the horology component.
