A curable formulation that provides, when hardened, an elastomeric material which is usable in additive manufacturing of a three-dimensional object is provided. The formulation is based on curable mono-functional and multi-functional elastomeric materials, in combination with a curable, multi-functional, non-elastomeric material and a curable material that comprises at least two hydrogen bond forming groups. L'invention concerne une formulation durcissable qui fournit, lorsqu'elle est durcie, un matériau élastomère qui peut être utilisé dans la fabrication additive d'un objet tridimensionnel. La formulation est basée sur des matériaux élastomères mono-fonctionnels et multifonctionnels durcissables, en combinaison avec un matériau non élastomère, multifonctionnel, durcissable, et un matériau durcissable qui comprend au moins deux groupes formant une liaison hydrogène.
