  • Formulation for 3D printing and a 3D printed article
    Patent number: 11845846
    Abstract: A flowable liquid formulation for 3D printing is described. The formulation comprises from 0.1 to 25 wt. % 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).
