Patent number: 9017589Abstract: 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.Type: GrantFiled: January 28, 2014Date of Patent: April 28, 2015Assignee: Stratasys Ltd.Inventors: Eliahu M. Kritchman, Eduardo Napadensky, Igal Zeytoun

Patent number: 7225045Abstract: A method and a system for three-dimensional printing of a three dimensional model is provided. The method includes dispensing a first interface material from a printing head, dispensing at least a second interface material from the printing headland combining the first and second interface material in pre-determined proportions to produce layers for forming the three-dimensional model. In one embodiment, the layers forming the construction layers of the model are formed from interface material having a harder modulus of elasticity from the layers forming the release layers, thereby allowing for the forming complex three-dimensional shapes.Type: GrantFiled: December 1, 2003Date of Patent: May 29, 2007Assignee: Object Geometries Ltd.Inventors: Hanan Gothait, Eduardo Napadensky, Igal Zeytoun
