Zusammenfassung:	The present invention relates to a thermosetting material for use in additive manufacturing, the material comprising at least one thermosetting resin and at least two curing compounds different from said thermosetting resin that are able to cure this/these thermosetting resin(s), wherein at least one curing compound is provided for curing during the additive manufacturing process and at least one curing compound is provided for curing during a post-curing step. The invention furthermore relates to a method of producing a cured 3D thermoset object comprising at least the steps of subjecting the material according to the present invention to an additive manufacturing process, obtaining a partially cured 3D thermoset object and subsequently subjecting the partially cured 3D thermoset object to a post-curing process to further cure the 3D thermoset object. Additionally, the invention relates to the use of the material in an SLS, FFF, CBAM, FGF or powder bed additive manufacturing process. La présente invention concerne un matériau thermodurcissable destiné à être utilisé dans la fabrication additive, le matériau comprenant au moins une résine thermodurcissable et au moins deux composés de durcissement différents de ladite résine thermodurcissable qui sont aptes à durcir cette/ces résine(s) thermodurcissable(s), au moins un composé de durcissement étant prévu pour le durcissement pendant le procédé de fabrication additive et au moins un composé de durcissement étant prévu pour le durcissement pendant une étape de post-durcissement. La présente invention concerne en outre un procédé de production d'un objet thermodurci 3D durci comprenant au moins les étapes consistant à soumettre le matériau selon la présente invention à un procédé de fabrication additive, obtenir un objet thermodurci 3D partiellement durci et soumettre ensuite l'objet thermodurci 3D partiellement durci à un procédé de post-durcissement pour durcir davantage l'objet thermodurci 3D. De plus, la présente invention concerne l'utilisation du matériau dans un procédé de fabrication additive de SLS, FFF, CBAM, FGF ou de lit de poudre.
