This LLNL invention is comprised of (1) a volumetric subtractive manufacturing system which can tomographically manufacture 3D structures with negative features (materials in negative space is degraded with light exposure), and (2) a hybrid volumetric additive/subtractive manufacturing system in which a gelled/solid structure is printed by resin material polymerization using one light, and…

LLNL has developed a system and method that accomplishes volumetric fabrication by applying computed tomography (CT) techniques in reverse, fabricating structures by exposing a photopolymer resin volume from multiple angles, updating the light field at each angle. The necessary light fields are spatially and/or temporally multiplexed, such that their summed energy dose in a target resin volume…

LLNL has developed a new active memory data reorganization engine. In the simplest case, data can be reorganized within the memory system to present a new view of the data. The new view may be a subset or a rearrangement of the original data. As an example, an array of structures might be more efficiently accessed by a CPU as a structure of arrays. Active memory can assemble an alternative…
