1. A method of solid freeform fabrication, comprising:
dispensing rows of at least one modeling material to form a layer of said at least one modeling material in a configured pattern corresponding to a shape of a slice of an object, each row being dispensed by inkjet technology;
solidifying said layer; and
repeating said dispensing and solidifying a plurality of times to provide a plurality of layers each comprising an interior and a periphery surrounding said interior, wherein said interior and said periphery are made of different combinations of modeling materials, and wherein said layers are arranged to form a bulk region of said object at least partially coated by a skin region of said object;
wherein at least one of said layers has a uniform thickness and comprises a row of two or more different modeling materials, and wherein said layers are arranged such that a distinguishable pattern made of said modeling materials is formed on said skin region.
