1. A method for manufacturing a hearing instrument, the method comprising:
placing a component support structure at least partially in a bath of a resin liquid, wherein the component support structure is user-specific, wherein one or more operative components of the hearing instrument are attached to or contained within the component support structure prior to the component support structure being at least partially placed in the bath of the resin liquid; and
while the component support structure is at least partially in the bath, performing volumetric 3-dimensional (3D) printing to form a shell of the hearing instrument attached to the component support structure.
