Abstract
The applicator is made of a material that is compatible with the cosmetic. In the manufacturing method, a digital model of the applicator is prepared, the material is conditioned in a raw form that is capable of flowing, and the material in raw form is solidified in slices that are defined by the digital model. The material in raw form is capable of being solidified by photo-polymerization, in particular by means of a light source comprising a laser, or else by sintering, in particular by means of a heat source comprising a laser. The applicator is a mascara brush or comb, for example.
