Patent number: 11809161Abstract: A system for determining a light intensity field for use in manufacturing a 3D object from a volume of material. The system receives a 3D specification of a 3D geometry for the 3D object that specifies voxels within the volume that contain material that is to be part of the 3D object. The system employs a cost function for effectiveness of a light intensity field in manufacturing the 3D object. The cost function may be an adjoint of an Attenuated Radon Transform that models an energy dose that each voxel would receive during manufacture of the 3D object using the light intensity field. The system applies an optimization technique that employs the cost function to generate a measure of the effectiveness of possible light intensity fields and outputs an indication of a light intensity field that will be effective in manufacturing the 3D object.Type: GrantFiled: July 13, 2020Date of Patent: November 7, 2023Assignees: Lawrence Livermore National Security, LLC, The Regents of the University of CaliforniaInventors: Maxim Shusteff, Kyle Champley, Erika Jo Fong, Hayden Taylor, Chi Chung Li, Trevor Rongey, Jr., Sui Man Luk, Heting Fu, Samira Feili, Joseph Toombs, Hossein Heidari

Patent number: 11701827Abstract: A multi-beam volumetric resin curing system and method for whole-volume additive manufacturing of an object includes a bath containing a photosensitive resin, a light source for producing a light beam, and a spatial light modulator which produces a phase- or intensity-modulated light beam by impressing a phase profile or intensity profile of an image onto a light beam received from the light source. The system and method also include projection optics which then produces multiple sub-image beams from the modulated light beam which are projected to intersect each other in the photosensitive resin to cure select volumetric regions of the resin in a whole-volume three-dimensional pattern representing the object.Type: GrantFiled: December 23, 2020Date of Patent: July 18, 2023Assignee: Lawrence Livermore National Security, LLCInventors: Maxim Shusteff, Christopher M.

Patent number: 11072160Abstract: The present disclosure relates to a system for forming a three dimensional (3D) part. The system may incorporate a beam delivery subsystem for generating optical signals, and a mask subsystem that receives the optical signals and generates optical images therefrom. A first one of the optical images activates a polymerization species of a photo-sensitive resin in accordance with illuminated areas thereof, to thus cause polymerization of select portions of the photo-sensitive resin to help form a layer of the 3D part. A second one of the optical images causes stimulated emission depletion of subportions of the polymerization species, simultaneously, over various areas of the layer, to enhance resolution of at least one subportion of the select portions of the photo-sensitive resin.Type: GrantFiled: August 23, 2016Date of Patent: July 27, 2021Assignees: Lawrence Livermore National Security, LLC, The Regents Of The University Of CaliforniaInventors: Ryan Hensleigh, Bryan D.

Patent number: 10647061Abstract: A method of forming a three dimensional (3D) object is disclosed. The method may involve providing a volume of photo-curable resin contained within an optically transparent resin container, and simultaneously directing optical projections from an optical subsystem at a plurality of angles ? through the volume of photo-curable resin. The optical beams are directed about a z axis extending through the volume of photo-curable resin. Each of the projections is provided with a calculated 2D spatial intensity function which creates a 3D intensity map. The projections act over a fixed temporal exposure period, during which the net exposure dose is sufficient to cure select portions of the volume of photo-curable resin, and to leave other portions uncured, to form a desired 3D part.Type: GrantFiled: May 12, 2017Date of Patent: May 12, 2020Assignees: Lawrence Livermore National Security, LLC, The Regents of the University of CaliforniaInventors: Brett Kelly, Robert Panas, Maxim Shusteff, Christopher Spadaccini, Hayden Taylor, Indrasen Bhattacharya

Patent number: 8999129Abstract: The present invention provides a mechanism for separating or isolating charged particles under the influence of an electric field without metal electrodes being in direct contact with the sample solution. The metal electrodes normally in contact with the sample are replaced with high conductivity fluid electrodes situated parallel and adjacent to the sample. When the fluid electrodes transmit the electric field across the sample, particles within the sample migrate according to their electrophoretic mobility.Type: GrantFiled: March 6, 2012Date of Patent: April 7, 2015Assignees: Lawrence Livermore National Security, LLC, The Board of Trustees of the Leland Stanford Junior UniversityInventors: Byoungsok Jung, Klint A.
