Zusammenfassung:	The present invention refers to a method for additive manufacturing a silicone elastomer and the silicone elastomer obtained therefrom. The present invention further refers to a two-part silicone composition W used in additive manufacturing such silicone elastomer. Wherein the first part of the silicone composition is charged into a liquid bath and the second part is charged into a dispensing head of a 3D printer. Proper selection of rheology behaviour for the first part in liquid bath has a contribution to the well-formed printed article. La présente invention concerne un procédé de fabrication additive d'un élastomère de silicone et l'élastomère de silicone obtenu à partir de celui-ci. La présente invention concerne en outre une composition de silicone en deux parties W utilisée dans la fabrication additive d'un tel élastomère de silicone. La première partie de la composition de silicone est chargée dans un bain liquide et la seconde partie est chargée dans une tête de distribution d'une imprimante 3D. Une sélection appropriée d'un comportement de rhéologie pour la première partie dans un bain liquide apporte une contribution à l'article imprimé bien formé.
