摘要：
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. High-stiffness, structurally-integrated, sacrificial structures are also included for the purposes of reduction or elimination of tooling during post-processing operations.
