Abstract
A method of forming a three-dimensional object in layerwise fashion by selectively solidifying a build material. The method solidifies the main part area, delays or pauses for a desired period of time to permit shrinkage to occur, and then, in multiple drawings of the main part borders, solidifies the borders from the portion closest to the main part outwardly to the portion farthest from the main part.
