A method of additive manufacturing of a three-dimensional object is disclosed. The method comprises sequentially forming a plurality of layers in a configured pattern corresponding to the shape of the object. Each layer is formed by dispensing at least one modeling material to form an uncured layer, and curing the uncured layer by radiation. In various exemplary embodiments of the invention the method comprises, for at least one layer, forming a stack of sacrificial radiation-protective layers to cover an exposed portion of the layer, such that an upper layer of the stack remains exposed during formation of any subsequent layer of the plurality of layers.
A system for additive manufacturing of a three-dimensional object, comprising;
A computer software product, comprising a computer-readable medium in which program instructions are stored, which instructions, when read by a computerized controller of an additive manufacturing system having a dispensing unit and a curing unit, cause said controller to operating said dispensing and curing units to sequentially form a plurality of layers in a configured pattern corresponding to the shape of a three-dimensional object, and a stack of sacrificial radiation-protective layers covering an exposed portion of at least one layer, such that an upper layer of said stack remains exposed during formation of any subsequent layer of said plurality of layers.
