A method and system for designing and displaying virtual models of custom ear devices

A computer-implemented method for designing one or more virtual models of custom ear devices, the method comprising:

• loading into one or more processors ear impression data,
• loading into the one or more processors one or more configuration requirements that comprise one or more requirements for accepting a target product,
• providing access for the one or more processors to a datastore comprising component and/or material information associated with one or more components and/or materials of the target product, the component and/or material information comprising a fixed value indicative of a fixed hierarchical order of the one or more components and/or materials, determining, using the one or more processors, one or more combinations between the component and/or material information from the datastore and the one or more configuration requirements, and assigning a combined value of a combined hierarchical order to each of the one or more combinations, wherein the combined value comprises at least the respective fixed value of the component and/or material information,
• designing one or more virtual models of custom ear devices based on the one or more combinations and the combined value,
• selecting the target product from the one or more designed virtual models of custom ear devices such that the target product fits the ear impression data, and generating a control file for a 3D printer, wherein the control file comprises instructions for manufacturing of the target product.
