3D Printing Mirror (Radial Lithography Surface Figuring)

The technology enables less expensive fabrication of mirrors without compromising quality. This is done with a 3D printing technique that uses lasers and a rotating platform to craft the desired shape of the mirror. The new method can print mirrors that can be used in large-aperture telescope applications such as space telescopes. It can also fabricate mirrors with asymmetric surfaces. All 3D printing processes will be guided by ‘in-situ metrology’ that will provide optical quality guidance.

Background: 
Additive manufacturing, also known as 3D printing, has shown potential for use in optics fabrication due to its ability to create complex structures that are difficult or impossible to produce with traditional manufacturing methods. Applications of additive manufacturing in optics include the production of lightweight, high-performance mirrors for use in space telescopes and the fabrication of micro-optical components for use in sensors and other devices. However, challenges such as surface roughness and the presence of voids or defects in printed materials must be addressed to fully realize the potential of additive manufacturing in optics. This technology aims to address those issues with this novel manufacturing method.
