Beschreibung
Zusammenfassung:	A 3D printed reflective optical device provides very high specific stiffness by employing a hollow housing design, has a closed face back face, filled with a high stiffness internal volume space filled with an open pore lattice structure. To reduce or eliminate tools during post-processing operations, a high stiffness, structurally integrated sacrificial structure is also included. 一种3D打印的反射性光学器件，通过采用空心壳体设计提供非常高的比刚度，具有封闭面背面，填充有高刚度的内部体积空间填充开孔晶格结构。为了在后处理操作期间减少或消除工具，还包括高刚度、结构集成的牺牲性结构。
