Abstract
The manufacture of a hearing instrument having a hard inner shell and a softer outer covering, for insertion into the ear canal of the user, may be accomplished using rapid manufacturing and prototyping techniques. Starting with a digital model of the ear canal, a mold for the softer outer covering may be fabricated using a process such as stereo lithography.
