Patent number: 9981425Abstract: An apparatus and method for making a three-dimensional object from a solidifiable material using a linear solidification device is shown and described. In certain examples, the linear solidification device includes a laser diode that projects light onto a scanning device, such as a rotating polygonal mirror or a laser scanning micromirror, which then deflects the light onto a photohardenable resin. As a result, the linear solidification device scans a line of solidification energy in a direction that is substantially orthogonal to the direction of travel of the laser diode. In other examples, the linear solidification device is a laser device array or light emitting diode array that extends in a direction substantially orthogonal to the direction of travel of the array.Type: GrantFiled: May 14, 2015Date of Patent: May 29, 2018Assignee: Global Filtration SystemsInventors: Ali El-Siblani, Alexandr Shkolnik

Patent number: 9975296Abstract: An apparatus and method for making a three-dimensional object from a solidifiable paste is shown and described. The apparatus includes a pastes spreader, at least a portion of which extends into the solidifiable paste. The container holding the solidifiable paste and the spreader are movable relative to one another. In one system, the spreader vibrates as the container and the spreader move relative to one another. In another system, the spreader is part of a spreader assembly in which a first spreader and second spreader are angled with respect to one another, and the assembly is rotatable and lockable into multiple rotational positions. A paste dispenser is also described which is configured to dispense paste while moving along a travel axis.Type: GrantFiled: February 6, 2015Date of Patent: May 22, 2018Assignee: Global Filtration SystemsInventor: Ali El-Siblani

Patent number: 9902112Abstract: An apparatus and method for making a three-dimensional object from a solidifiable material using a linear solidification device with a vacuum blade is shown and described. In certain examples, the vacuum blade travels at a fixed distance relative to the linear solidification device as the linear solidification device travels along a travel axis. In other examples, the linear solidification device and the vacuum blade travel along the travel axis independently of one another.Type: GrantFiled: April 7, 2015Date of Patent: February 27, 2018Assignee: Global Filtration SystemsInventors: Ali El-Siblani, Alexandr Shkolnik

Patent number: 9586364Abstract: An apparatus and method for making a three-dimensional object from a solidifiable material using a linear solidification device and contourless object data is shown and described. A voxel matrix is superimposed over an object model defined by three-dimensional object data to determine active voxels that intersect at least a portion of the object model. The active voxels are related to a path generation reference frame of an apparatus for making a three-dimensional object to generate solidification energy source event data that defines scanning (y) axis locations and/or solidification times at which a linear solidification device supplies solidification energy to a solidifiable material.Type: GrantFiled: November 27, 2013Date of Patent: March 7, 2017Assignee: Global Filtration SystemsInventors: Ali El-Siblani, Alexandr Shkolnik, Alexander Nam, Mohamad Janbain

Patent number: 9561623Abstract: Methods and apparatuses for making three-dimensional objects from multiple solidifiable materials is shown and described. Multiple solidifiable material container assemblies are provided for holding different solidifiable materials. Relative movement between the solidifiable material container assemblies and a build platform allows the solidifiable materials to be switched as an object is built. Several exemplary cleaning stations are provided for removing residual solidifiable materials from the surface of the three-dimensional object as it is built to better ensure smooth transitions between materials on the finished object.Type: GrantFiled: July 9, 2014Date of Patent: February 7, 2017Assignee: Global Filtration SystemsInventors: Ali El-Siblani, Alexandr Shkolnik

Patent number: 9539072Abstract: A dental arch model and method for making the same is shown and described. The dental arch model includes a connector having opposite ends that connect to a respective one of the arch legs. The connector has a three-dimensional shape but does not include a surface that is both planar and parallel to the base of the arch connector along more than two thirds of the arch connector's length. In certain examples, the connector is in the shape of a prism or a trapezoid. In other examples, the connector has an upper surface that is sloped relative to the base of the arch connector. The arch connector may also include a plurality of fluid passageways for allowing fluid flow from an interior area between the inner walls of the arch connector to a location outside of the connector.Type: GrantFiled: December 16, 2013Date of Patent: January 10, 2017Assignee: Global Filtration SystemsInventor: Ali El-Siblani

Patent number: 9486944Abstract: A solidification substrate assembly for making a three-dimensional object from a solidifiable material includes a solidification substrate assembly. In certain examples, the solidifiable material solidifies in contact with the solidification substrate, and the tilting of the substrate and/or or the use of a peeling member facilitates separation of the substrate from the solidified material. In other examples, the solidification substrate assembly includes a film that is adjacent to a rigid or semi-rigid layer. The solidifiable material solidifies in contact with the film, and a peeling member peels the film away from the solidified material. Intelligent solidification substrate assemblies are also described in which a force sensor determines when to expose the solidifiable material to solidification energy and/or whether to use a peeling member to separate the solidification substrate from a solidified objection section.Type: GrantFiled: January 14, 2013Date of Patent: November 8, 2016Assignee: Global Filtration SystemsInventors: Ali El-Siblani, Alexandr Shkolnik
