An object produces from a computer data base by representing the object in the data base as a solid voxels surrounded by support voxels within a volume. The data base representation of the object as the solid voxels is converted to a data base representation of the object as a shell of solid voxels surrounding filler support voxels, and the object from said converted data base representation is constructed in a layerwise fashion. A first material is dispensed in liquid form at selected locations of a target surface, and the selected locations correspond to the shell locations of a cross-section of an object. The first material solidifies after being dispensed; a second material is applied at locations of said target surface other than the shell locations at which the first material is dispensed, to form another target surface. The dispensing and applying is repeated to form an object comprising a shell of the first material surrounding said second material, and surrounded by the second material. The portion of said second material surrounding said shell is removed, relative to the first material, to leave an object formed of a shell of the first material surrounding a portion of the second material.

A method of producing an object from a computer data base, wherein said object is represented in said data base as a plurality of solid voxels surrounded by a plurality of support voxels within a volume, said method comprising the steps of: converting said data base representation of said object as a plurality of solid voxels to a data base representation of said object as a shell of solid voxels surrounding a plurality of filler support voxels; and constructing said object from said converted data base representation, in a layerwise fashion, by a method comprising the steps of: dispensing a first material in liquid form at selected locations of a target surface, said selected locations corresponding to the shell locations of a cross-section of an object, wherein the first material solidifies after being dispensed; applying a second material at locations of said target surface other than the shell locations at which said first material is dispensed, to form another target surface; repeating said dispensing and applying steps to form an object comprising a shell of said first material surrounding said second material, and surrounded by said second material; selectively removing the portion of said second material surrounding said shell, relative to said first material, to leave an object formed of a shell of said first material surrounding a portion of said second material.
