Abstract

The present invention describes a process for producing a three-dimensional object, comprising: providing a material to be solidified, the material comprising a filler and a binder; delivering electromagnetic radiation and/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 wherein an energy density of electromagnetic radiation and/or synergistic stimulation is varied within said pattern or image and/or between patterns or images of different building regions of said material. The present invention may be directed also to a system where different first and second materials are to be solidified. The present invention further provides a freeform fabrication system, and a freeform three-dimensional object having unique properties as well as products derived therefrom, such as sintered products.
