Patent ID: 8003040

Claim:
A process for producing at least one three-dimensional object, comprising: providing a material to be solidified; delivering electromagnetic radiation or synergistic stimulation in a pattern or an image to a building region for solidifying said material, wherein said delivering of electromagnetic radiation and/or synergistic stimulation is performed selectively to a defined area or volume of said material to be solidified; and controlling an energy density of electromagnetic radiation or synergistic stimulation in a border region of said pattern or image relative to a non-border region of said pattern or image based on an observed or determined degree of either out-shining of electromagnetic radiation or synergistic stimulation towards outside regions, or in-shining of electromagnetic radiation or synergistic stimulation into internal regions, respectively, across a border region or border regions of the three-dimensional object by adjusting an energy intensity of electromagnetic radiation or synergistic stimulation in the border region of said pattern or image relative to the non-border region of said pattern or image, wherein the step of adjusting the energy intensity of electromagnetic radiation or synergistic stimulation in the border region of said pattern or image relative to the non-border region of said pattern of image is dependent on at least one selected from: (a) intensity of electromagnetic radiation or synergistic stimulation delivered to said defined area or volume of said material to be solidified; (b) total shape or contour shape of said defined area or volume of said material to be solidified; (c) size of said defined area or volume of said material to be solidified; and (d) material to be solidified.
