coextrusion nozzle takes 3 materials and prints them together in a coaxial geometry

LLNL’s novel approach is to use Direct Ink Write (DIW) with a co-extrusion nozzle to enable the extrusion of multiple materials as one coil.  With this method, LLNL researchers were able to produce an insulating wire that is composed of three different materials, axial conducting and insulating from its inner core to its outer sheath.  After heat treatment, the printed wireI was then tested…

Optimization using component-wise ROM

Beam Element-based Topology Optimization (“BETO”) is one of the conventional ways to design microstructures.  It starts with an initial design that is composed of many beam elements.  LLNL’s invention uses accurate Component-wise Reduced Order Models (“CWROM”) rather than the inaccurate beam elements.  In doing so, the process becomes computationally efficient and fast, as each reduced order…

Schematic of a mechanical logic gate

LLNL’s approach to designing logic gates uses heuristic as well as with the Freedom and Constraint Topologies (FACT) methods; these gates are then produced using existing additive manufacturing processes.  The 10,122,365 and 10,678,293 patents describe how to fabricate the gates; the 10,855,259 patent describes ho
