Abstract: ABSTRACT The present invention relates to a process for fabrication and integration of adaptive silicone skin on a facially expressive humanoid head (100), comprising a silicone or elastomeric facial skin layer (102) with region-specific thickness variations to enable realistic human-like expressions. The assembly includes a plurality of interlocking elements (104) formed of thermoplastic polyurethane (TPU) or similar elastomeric material, integrally attached at protrusions on the inner surface of the facial skin. A reusable, multi-part 3D-printed mould system (106), composed of outer cavity shells (108) and internal core inserts (110), is parametrically designed to allow easy customization of different humanoid face geometries and expression variants. The mould components are fabricated using variable infill densities- denser [high infill (118)] in load-bearing areas and sparser [low infill (116)] in non-critical zones to reduce material usage and print time without compromising structural integrity. Attachment to the internal frame (112) is achieved via a hybrid mechanism combining mechanical interlocks and selective chemical bonding using silicone adhesive at a silicone adhesive zone (114), ensuring secure, tamper-resistant, yet serviceable integration. The invention facilitates enhanced lifelike expressiveness, modular maintenance, cost-efficient personalization, and optional pigmentation for improved aesthetic realism.
