Patent number: 11926103Abstract: An approach to precision additive fabrication uses jetting of cationic compositions in conjunction with a non-contact (e.g., optical) feedback approach. By not requiring contact to control the surface geometry of the object being manufactured, the approach is tolerant of the relative slow curing of the cationic composition, while maintaining the benefit of control of the deposition processes according to feedback during the fabrication processes. This approach provides a way to manufacture precision objects and benefit from material properties of the fabricated objects, for example, with isotropic properties, which may be at least partially a result of the slow curing, and flexible structures, which may not be attainable using conventional jetted acrylates.Type: GrantFiled: November 12, 2021Date of Patent: March 12, 2024Assignee: Inkbit, LLCInventors: Wenshou Wang, Gregory Ellson, Yan Zhang, Desai Chen, Javier Ramos, Wojciech Matusik, Kiril Vidimce

Patent number: 11155040Abstract: A closed-loop adaptive material deposition apparatus and method uses a scanning system to monitor an additively manufactured object as it is being fabricated and adapting the geometric shape and material composition of the subsequent layers based on the scan data. The scanning system repeatedly captures geometric and/or material information of a partially manufactured object with optional auxiliary objects inserted during the manufacturing process. Based on this information, the actual surface geometry and/or actual material composition is computed. Surface geometry may be offset and used as a slicing surface for the next portion of the digital model. The shape of the slicing surface may then be recomputed each time the system scans the partially fabricated object.Type: GrantFiled: October 25, 2019Date of Patent: October 26, 2021Assignee: Massachusetts Institute of TechnologyInventors: Wojciech Matusik, Allen S.

Patent number: 11097464Abstract: Devices and methods are described that provide printing of three-dimensional objects using reactive materials such as materials that result in a polyurethane formulation. Three-dimensional printing in accordance with the present disclosure can be performed using an inkjet printer or other systems that deposit or dispense material. A formulation made up of two or more reactive materials and, optionally, one or more UV-curable materials is also provided. The materials can be jetted based on a desired configuration to achieve a maximum reaction between materials, and can be based on desired jetting or molar ratios. By heating or applying energy on the jetted materials, their reaction and related solidifying can be accelerated. Corrective printing is also provided for, and can be used at desired intervals to eliminate printing errors relative to the object as modeled. Systems and methods used in conjunction with all of the same are provided.Type: GrantFiled: August 25, 2017Date of Patent: August 24, 2021Assignee: Massachusetts Institute of TechnologyInventors: Wojciech Matusik, Wenshou Wang, Kiril Vidimce, Javier Ramos

Patent number: 10830578Abstract: A method and an apparatus are directed to characterizing a continuously moving 3D object via interferometry-based scanning. The method includes repeatedly forming several depth characterizations of the 3D object along respective scan lines of a plurality of scan lines on the surface of the 3D object. During this scanning, the 3D object is undergoing its continuous motion. The method further includes combining the determined depth characterization along the scan lines of the plurality of scan lines to form a depth map representing at least a depth of a portion associated with a location on the surface of the 3D object in the third direction on a grid of locations arranged in the first and second directions. Forming the depth characterizations includes scanning a frequency-dispersed pulsed optical signal in a first direction across the continuously moving 3D object, said 3D object moving in a second direction substantially orthogonal to the first direction.Type: GrantFiled: October 17, 2019Date of Patent: November 10, 2020Assignee: Inkbit, LLCInventors: Aaron Weber, Kiril Vidimce, Walter H.

Patent number: 8797323Abstract: A dynamic volumetric medium, such as hair, fog, or smoke, may be represented, for purposes of shadow mapping, by transmittance versus depth data for that medium. In one embodiment, the representation may take the form of a plot of transmittance versus depth, with nodes where the transmittance changes non-live linearly with respect of depth into the medium. The number of nodes in the representation may be reduced to reduce memory footprint and to enable the storage of the representation on the same chip doing the shadow mapping. In some embodiments, the number of nodes may be reduced, one node at a time, by removing the node whose underlying trapezoid has the least area of all the remaining nodes.Type: GrantFiled: January 18, 2011Date of Patent: August 5, 2014Assignee: Intel CorporationInventors: Marco Salvi, Aaron Lefohn, Andrew T.

Input data is received at a graphics pipeline of a graphics processing unit to be processed and generated into a final image to be displayed on a display device of a computer system. Geographic primitives are obtained from processing the input data, and neighbor aggregation of pixels within the geographic primitives is performed. The neighbor aggregation of the pixels includes rendering list texture of the pixels by merging the geographic primitives.Type: GrantFiled: April 9, 2010Date of Patent: July 8, 2014Assignee: Intel CorporationInventors: Paul LaLonde, Kiril Vidimce, Larry Dean Seiler

Publication number: 20140022273Abstract: In some cases, instead of providing one color sample for every primitive overlying a pixel, surfaces made up of more than one primitive may be identified. In some cases, a surface may be identified that is likely to be of the same color. So, in such case, only one color sample may be needed for more than one primitive.Type: ApplicationFiled: October 18, 2011Publication date: January 23, 2014Inventors: Kiril Vidimce, Marco Salvi
