Abstract:
1. A process for producing a three-dimensional object using an imaging unit comprising a predetermined number of discrete imaging elements or pixels, the process comprising: providing a material to be solidified, the material comprising a filler and a binder; 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; wherein an energy density of electromagnetic radiation or synergistic stimulation is at least partially varied within said pattern or image by controlling a gray value or a color value of at least a part of the discrete imaging elements or pixels, and a variation of intensity of electromagnetic radiation or synergistic stimulation within said pattern or image is controlled by a control unit such that when the filler is a reflecting or scattering filler, an energy density of the electromagnetic radiation or synergistic stimulation delivered to a boundary region of said pattern or image is lower than an energy density of the electromagnetic radiation or synergistic stimulation delivered to an inner region of said pattern or image.
