摘要： A method of additive manufacturing of a three-dimensional object is disclosed. The method comprises sequentially forming a plurality of layers each patterned according to the shape of a cross section of the object. In some embodiments, the formation of at least one of the layers comprises performing a raster scan to dispense at least a first building material composition, and a vector scan to dispense at least a second building material composition. The vector scan is optionally along a path selected to form at least one structure selected from the group consisting of (i) an elongated structure, (ii) a boundary structure at least partially surrounding an area filled with the first building material, and (iii) an inter-layer connecting structure.

摘要： A method for printing three dimensional objects and support compositions are disclosed. The composition includes at least one curable component and at least one non-curable component, the non-curable component being a polyol, a glycol or water, wherein none of said non-curable components is reactive with any of said curable components. The composition has a first viscosity of 20-500 cps at ambient temperature and a second viscosity of less than 20 cps at temperature higher than the ambient temperature. The composition results in a solid, a semi solid or a gel type material after radiation.

摘要： A method of additive manufacturing of a three-dimensional object includes sequentially dispensing and solidifying a plurality of layers. The plurality of layers may be formed with a plurality of different colored model materials, a flexible material arranged in a configured pattern to form a sacrificial structure at least partially encompassing the object, and a soft material. The soft material is arranged in a configured pattern to provide separation between the model material and the sacrificial structure. The plurality of different colored model materials is arranged in a configured pattern corresponding to the shape and color definition of the object.

摘要： A method of printing a three-dimensional (3D) object and a support construction for the 3D object includes depositing a model material, layer-by-layer, on a fabrication platform, to print a first portion of the 3D object, and depositing a support material, layer-by-layer on the fabrication platform, to print the support construction, wherein, in a predetermined number of the deposited layers, the model material and the support material are deposited such that a gap is formed between a surface of the first portion of the 3D object and a surface of the support construction.

摘要： 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.

摘要： A three dimensional printing method for producing a self-destructible temporary structure, comprising: depositing, layer by layer, a degradable material solution having a biosynthetic copolymer as a degradable component and a disintegrating agent solution comprising enzyme as the disintegrating agent, wherein the disintegrating agent is capable of disintegrating the degradable component. The steps include curing deposited layers to form gel layers and activating the disintegrating agent by an external trigger during or after depositing the disintegrating agent to gradually degrade the degradable component.

摘要： A method of layerwise solid freeform fabrication is disclosed. The method comprises, for each of at least a few of the layers, dispensing and hardening at least a first modeling material and a second modeling material to form a core region and one or more envelope regions at least partially surrounding the core region. In some embodiments, the ratio between the elastic moduli of adjacent regions, when hardened, is from about 1 to about 20.
