Title (EN) FORMULATION FOR 3D PRINTING AND A 3D PRINTED ARTICLE
(FR) FORMULATION POUR IMPRESSION 3D ET ARTICLE IMPRIMÉ 3D
Abstract:
(EN) A flowable liquid formulation for 3D printing is described. The formulation comprises from 0.1 to 25wt.% radiopaque particles, wherein at least 50% by weight of the particles have a diameter of at most 100 nm. The formulation further comprises monomeric, oligomeric and/or polymeric precursors adapted for polymerization to form a solidified article. Also described is an article (100) formed by 3D printing, the article (100) comprising a first 3D printed region (110) having a first radiopacity and a second 3D printed region (120) having a second radiopacity, wherein the first radiopacity is greater than the second radiopacity. Also described is a method of forming the article (100).
(FR) L'invention concerne une formulation liquide fluide pour impression 3D. La formulation comprend de 0,1 à 25 % de particules radio-opaques, au moins 50 % en poids des particules ayant un diamètre d'au maximum 100 nm. La formulation comprend en outre des précurseurs monomères, oligomères et/ou polymères conçus pour la polymérisation afin de former un article solidifié. L'invention concerne également un article (100) formé par impression 3D, l'article (100) comprenant une première région imprimée 3D (110) ayant une première radio-opacité et une seconde région imprimée 3D (120) ayant une seconde radio-opacité, la première radio-opacité étant supérieure à la seconde radio-opacité. L'invention concerne également un procédé de formation de l'article (100).
