  • 3D PRINTING OF HIGH STIFFNESS-TO-WEIGHT REFLECTIVE OPTICS
    Publication number: 20230264260
    Abstract: A 3D-printed reflective optic providing very high specific stiffness through the utilization of a hollow shelled design, with closed back, filled with high-stiffness internal volumetric space-filling open-cell lattice structures. Structurally-integrated sacrificial structures are included for the purposes of reduction or elimination of tooling during post-processing operations.
    Type: Application
    Filed: April 21, 2023
