1. A process for manufacturing a fake nail, comprising:
a) producing by additive manufacture, from 3D digital data originating from the acquisition of a relief of a finger intended to receive the false nail, a mold using a first material,
b) depositing onto said mold a layer formed from at least one adhesive composition, the deposition of the adhesive composition being performed by a method selected from the group consisting of 2D printing, 3D printing, spraying, dipping and transfer, and
c) after implementing b), depositing onto said mold at least one layer of a coating of a second material, different from the first, so as to at least partly cover the layer of adhesive composition and to form the false nail, the deposition of the coating being performed with a method selected from the group consisting of thermoforming, 2D printing, 3D printing, injection, dipping and transfer.
