Patent ID: 8658076

Claim:
A process for producing at least one three-dimensional object, or for preparing the production thereof, said production process being of a type 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 or synergistic stimulation is performed selectively to a defined area or volume of said material to be solidified; wherein said production or said preparation process includes the steps of: performing a virtual or actual solidification step, in which the degree of either out-shining electromagnetic radiation or synergistic stimulation towards outside regions, or in-shining electromagnetic radiation or synergistic stimulation into internal regions respectively across a border region or border regions of a three-dimensional object to be constructed is observed or determined, and adapting the energy density of electromagnetic radiation or synergistic stimulation in said border region(s) in response to said observed or determined degree of out- or in-shining across the border region(s).
