Innovative material system and process for the manufacture of patient-specific comfort earmolds for the hearing acoustics, audio and hearing protection industry

摘要

The invention relates to a method for producing a molded body with the aid of a radiation-induced printing process, characterized in that the molded body is produced from a liquid or viscous material which has a starting component with cycloolefinic groups, a thiol with at least two thiol groups per molecule and an initiator and / or contains catalyst for the light-induced thiol-ene addition reaction between the thiol groups and a double bond of the cycloolefinic groups, and - the solidification takes place in that light from a radiation source is directed onto an area of a surface of a substrate, a layer located there the liquid or viscous material is subjected to an organic polymerization by the action of radiation and is thereby solidified, whereupon successive further layers of the liquid or viscous material, each on the layer of the last solidified material as located, are solidified with the aid of this radiation source. The invention further relates to a shaped body made of a material which was formed by a photoinduced thiol-ene addition reaction of a thiol compound having at least two thiol groups per molecule to a starting component with cycloolefinic groups, obtainable according to the above Method, characterized in that the molded body undergoes a drop in its storage modulus of at least 1500 MPa within a temperature window of -10 ° C to 80 ° C with a temperature increase of at most 20 K.
