Title
(EN) ADDITIVE MANUFACTURING OF RADIOLOGICAL PHANTOMS
(FR) FABRICATION ADDITIVE DE FANTÔMES RADIOLOGIQUES
Abstract
(EN)
A formulation usable as a modeling material formulation in additive manufacturing of a three-dimensional object and additive manufacturing methods utilizing same are provided. The formulation comprises one or more curable materials; and a radiopaque material, and features, when hardened, a CT number of at least 100 HU at 70 kV. Objects made by the additive manufacturing method utilizing the formulation are usable as radiological phantoms.

L'invention concerne une formulation utilisable en tant que formulation de matériau de modelage dans la fabrication additive d'un objet tridimensionnel et des procédés de fabrication additive l'utilisant. La formulation comprend un ou plusieurs matériaux durcissables; et un matériau radio-opaque, la formulation présentant, après durcissement, un nombre CT d'au moins 100 UH à 70 kV. Les objets réalisés par le procédé de fabrication additive utilisant la formulation peuvent être utilisés en tant que fantômes radiologiques.
