  • ADDITIVE MANUFACTURING PROCESS
    Publication number: 20220031576
    Abstract: An additive manufacturing process comprising: (a) providing a curable composition comprising: (i) a filler comprising glassflakes having a diameter D3,99 as determined by light scattering in the range of from 5 to 150 ?m; and (ii) one or more curable compounds; (b) controlling an apparatus to form an object by using the curable composition, whereby the curable composition passes a discharge orifice having a minimum diameter ?min, wherein the ratio of the minimum diameter of the discharge orifice to the diameter D3,99 of the glassflakes (?min/D3,99) is in the range of 2 to less than 10; and wherein the median diameter D3,50 of the glassflakes is larger than the thickness of the glassflakes.
