Abstract

L'invention concerne un procédé servant à produire des embouts d'aides auditives à propriétés hétérogènes des matériaux sur la base de la technologie de fabrication SFF (solide en formes libres) d'impression tridimensionnelle combinée à la CAO. Selon ce procédé, au moins deux ou plusieurs matériaux à modeler et au moins un matériau support sont appliqués par couches ou brins sur une base fournie au moyen d'un dispositif d'application commandé par ordinateur. Une fois appliqués, un ou plusieurs brins ou couches sont lissés à l'aide d'un appareil de planarisation, puis sont durcis par rayonnement actinique avant l'application de la couche ou du brin suivant ou des couches ou des brins suivants. Chaque brin ou couche des matériaux à modeler est une formulation polymérisable qui peut être traitée dans son état non polymérisé par le dispositif d'application.
