Abstract
Method for manufacturing by photolithography a resin multilayer mould (') including a cavity (′) provided with an inlet (′) for the manufacture of a horological component, including producing at least two resin layers of the mould (′), by producing a first resin layer (C; C′) having a first through-opening or open opening (′) oriented in the direction of the inlet (′) of the mould to delimit a first volume of the cavity (′) of the mould (′), and producing a second resin layer (C; C′) including a rigid film and having a second through-opening (′) that delimits a second volume of the cavity (′) of the mould (′) and is at least partly superposed on the first through-opening or open opening (′), the second resin layer partly covering that same first through-opening or open opening (′).
