Zusammenfassung:	Thermoset compositions and methods for forming three-dimensional articles via an additive fabrication process, and articles made therefrom are disclosed herein. In an embodiment, a composition comprises a first network-forming component comprising a first oligomer comprising a backbone and having at least 2 polymerizable groups, one or more first network monomers, and a first network initiator. The backbone of the first oligomer comprises a polyepoxide based on Bisphenol A, F, or S, a polyepoxide based on hydrogenated Bisphenol A, F, or S, a polycarbonate, or a polyimide. The composition may further comprise a second network-forming component. L'invention concerne des compositions thermodurcissables et des procédés de formation d'articles tridimensionnels par l'intermédiaire d'un processus de fabrication additive, et des articles fabriqués à partir de celles-ci. Dans un mode de réalisation, une composition comprend un premier constituant de formation de réticulation comprenant un premier oligomère comprenant un squelette et ayant au moins 2 groupes polymérisables, un ou plusieurs premiers monomères de réticulation, et un premier initiateur de réticulation. Le squelette du premier oligomère comprend un polyépoxyde à base de bisphénol A, F ou S, un polyépoxyde à base de bisphénol A, F ou S hydrogéné, un polycarbonate ou un polyimide. La composition peut en outre comprendre un second constituant de formation de réticulation.
