Method for manufacturing a horological component and component produced according to said method

A method for manufacturing at least one horological component, comprising:

• a) providing a substrate and applying a first resin layer of photosensitive resin on the substrate;
• b) performing a hot stamping, using a stamp, of the first resin layer, by pressing the stamp up to a predefined distance from the substrate so as to keep a layer of resin, in order to shape the first resin layer, the stamp being made of transparent material;
• c) irradiating the shaped first resin layer through the stamp while the stamp is pressed against the substrate and in contact with the first resin layer in order to define at least a first level of the component;
• d) applying a second layer of photosensitive resin covering a resultant structure from step c), then irradiating the second resin layer through a mask defining a second level of the component and dissolving non-irradiated regions of the second photosensitive resin layer in order to form a mould comprising a first level and a second level;
• e) depositing an electrically conductive layer on surfaces of the first resin layer and the second resin layer;
• f) depositing a metal layer by electroforming in the mould, starting from the electrically conductive layer, in order to form the component;
• g) machining the metal layer by a mechanical method, so as to adjust a height of the component, and releasing the component.
