A method for reducing curl in three dimensional computer generated models, created by the sequential exposure of adjacent layers of a photoformable composition, comprising exposing each layer twice, the first exposure being with an image modulated exposure further modulated to produce a series of isolated, anchored islets along the imaged areas, and the second exposure also being image modulated but without the additional modulation, so as to fuse the islets into a continuous solid image. |
