A heater element for formed components is disclosed, along with the final formed component itself. The heater element is produced by photochemically etching a suitable heater track pattern from porous metallized fabric such a nickel coated woven polyester. The heater element is located within a mold. Thermo-formable material is then applied to the mold and the final component is shaped according to the shape of the mold. The final component has a heater element located within it. The component may have microencapsulated agents for initiation by operation of the heater element. Furthermore, the final component may have one or more digital images printed onto the surface for the purposes of decoration or personalization.
