摘要：
In a method to create a hearing aid housing shell and a negative cast for a hearing aid to be fitted to a patient's ear canal, a 3D jet printer apparatus is provided able to build a 3D part by injecting both the soft material and a hard material with the soft material serving as a support for the hard material. The 3D file is input to the 3D jet printer apparatus to build the hearing aid shell with the hard material and the combined negative cast with the soft material. The negative cast is used to check a quality of the hearing aid shell and to add external features to the shell by fitting the shell into the negative cast.
