Patent number: 11850790Abstract: The present disclosure relates to a volumetric additive manufacturing system for forming a structure from a volume of resin using microwave energy. The system makes use of an electronic controller and at least one beam forming algorithm accessible by the electronic controller for generating information relating to an amplitude and a time delay for forming a microwave signal, where the microwave signal will be used in irradiating a build volume, and where the build volume is formed by the volume of resin. A microwave signal generating subsystem is included which is responsive to the information generated by the beam forming algorithm, and which generates a microwave signal using the amplitude and the time delay determined by the beam forming algorithm. An antenna is used to receive the microwave signal and project the microwave signal as a microwave beam, in accordance with the amplitude and time delay, into the build volume to form the structure.Type: GrantFiled: November 3, 2021Date of Patent: December 26, 2023Assignee: Lawrence Livermore National Security, LLCInventors: Saptarshi Mukherjee, Tammy Chang, Joseph W.

Publication number: 20150079299Abstract: A method for coating target surfaces by spraying an atomized liquid formulation of a volatile solvent, a dispersant, and adhesion promoter, a polymer, a plasticizer and particulates of an active material and vaporizing the solvent from the spray droplets to form deformable solid particles in flight that impact the target surface to form a coating. The temperature of the atomizing gas used to form the spray and the liquid formulation temperatures can be manipulated to accelerate or decelerate the evaporation of solvent and balance the heat of vaporization of the solvent in the spray liquid so that condensation of ambient vapors in the atmosphere surrounding the deposition target is prevented.Type: ApplicationFiled: September 19, 2014Publication date: March 19, 2015Applicants: LAWRENCE LIVERMORE NATIONAL SECURITY, LLC, THE REGENTS OF THE UNIVERSITY OF CALIFORNIAInventors: Herbert B.
