摘要： A method for forming three dimensional objects is disclosed. The method includes printing building material, layer by layer, to form a three dimensional object on a printing tray by moving a printing block that comprises a printing head , at least two curing sources and a leveler in forward and reverse passages. The printing is done by moving the printing block in a forward passage when the distance between the printing block and the printing tray is such that the leveler does not touch a layer being built, adjusting a height position of the printing tray relative to the printing block prior to printing a reverse passage and moving the printing block in the reverse passage, wherein during the reserve passage the leveler touches and levels the layer being built.

摘要： Methods of printing a three-dimensional object, layer by layer are provided. Layers are formed by printing a bulk region with a white building material; inkjet printing a circumferential region surrounding the bulk region that is part of an apparent colored surface of the three-dimensional object, the circumferential region includes colored voxels formed by depositing a transparent building material and one or more color additive materials and inkjet printing a transparent layer around the circumferential region.

摘要： A method of three-dimensional fabrication of an object is disclosed. The method comprises: forming a plurality of layers in a configured pattern corresponding to the shape of the three-dimensional object, at least one layer of the plurality of layers being formed at a predetermined and different thickness selected so as to compensate for post-formation shrinkage of the layer along a vertical direction. In various exemplary embodiments of the invention spread of building material of one or more layers is diluted at least locally such as to maintain a predetermined thickness and a predetermined planar resolution for the layer.

摘要： Apparatus for producing a three-dimensional model by sequentially forming layers of photopolymer material one on top of the other responsive to data defining the three-dimensional model is disclosed. The apparatus includes at least one printing head configured to dispense the photopolymer material, an array of LEDs controllable to provide radiation to polymerize the photopolymer material and a controller. The controller is configured to control the at least one printing head to dispense the photopolymer material to sequentially form the layers of material. The controller is also configured to turn on the array of LEDs to provide the radiation to cure the photopolymer material when situated above the model and to turn off the array of LEDs when not situated above the model.
