Abstract
In a method for producing an implant from a biocompatible silicone, a 3D mathematical model of an implant to be produced is used to create a 3D model of a casting mold for the implant as a negative. The casting mold is produced from a polymeric material through an additive manufacturing process and coated through vapor deposition of a coating material from the parylene family at least in a region that comes into contact with the biocompatible silicone to be cast. A platinum-catalyzed 2-component thermosetting silicone as the biocompatible silicone for the implant is introduced into a mold cavity of the coated casting mold, with a residence time of the implant in a patient's body of more than 29 days. The casting mold is heated to vulcanize the biocompatible silicone, and after cooling down the vulcanized implant is demolded from the casting mold.
