Claim Text:
1. A system for three-dimensional fabrication of an object, comprising: a three-dimensional fabrication apparatus having a leveling device and being designed and constructed to form a plurality of layers of building material in a configured pattern corresponding to the shape of the three-dimensional object; a controller having a circuit configured to apply a dilution transformation to at least one bitmap respectively characterizing at least one layer of said plurality of layers, and to transmit control signals to said three-dimensional fabrication apparatus to ensure that for said at least one layer of said plurality of layers, said apparatus forms, according to said at least one transformed bitmap, an interior region surrounded by a peripheral region, wherein a thickness of said interior region is lower than a thickness of said peripheral region, wherein said leveling device is configured for leveling at least said peripheral region by removing material at least from said peripheral region so as to straighten at least said peripheral region.
