Abstract:
An improved method of stereolithographically forming a three-dimensional object from layers of a material capable of physical transformation upon exposure to synergistic stimulation comprising the steps of receiving data descriptive of cross-sections of the three-dimensional object, each cross-section representing one layer of the object to be formed, forming layers of said material, and selectively exposing said layers to synergistic stimulation according to said data descriptive of said cross-sections to build up the three-dimensional object layer-by-layer, the improvement comprising the steps of:modifying data descriptive of at least a portion of at least one cross-section by shifting said data from a first cross-section to a second cross-section which is located at least one layer thickness from said first cross-section; and using said modified data in forming said three-dimensional object.
