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 µm； 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 Φmin,wherein the ratio of the minimum diameter of the discharge orifice to the diameter D3,99 of the glassflakes (Φmin/D3,99) is in the range of 2 to less than 10.
