Method of coating an SLA part

摘要

A method for producing a high gloss exterior finish on a hearing aid ear shell. The method consists of the steps of: coating the ear shell with a UV-curable substance and/or a stereo-lithography resin; draining the UV-curable substance off the ear shell; exposing the ear shell to UV light to cure the UV-curable substance; removing any excess of the UV-curable substance; and exposing the UV-curable substance to UV light a second time.
