Envi-
siontec is a major player in this market as a 3D printer supplier. Danish Widex is special-
ized in this field as a tech service company and has developed an almost invisible 3D prin-
ted micro hearing aid and the “CAMISHA” process (Computer-Aided-Manufacturing-For-
Individual-Shells-For-Hearing-Aids) which is used widely throughout the industry. Other
players in this field are Siemens and Phonak.
