标题： Use of 3D printing in astronomical mirror fabrication

摘要： 在本文中，我们探讨了3D打印在天文学镜片制造中的可能性。 利用3D打印的优势来解决传统制造引起的现有问题，本文研究了两种概念验证的镜片制造策略。 第一个概念是一种可变形镜片，其嵌入了执行器支撑系统，以最小化镜片组装过程中由粘接界面引起的误差。 第二个概念是通过在镜片背面实施印刷的厚度分布，将应力镜片抛光（SMP）技术适应于各种镜片形状。 本文为两项研究提供了设计调查和原型计划。 显示英文摘要

摘要： In this paper we are exploring the possibilities of 3D printing in the fabrication of mirrors for astronomy. Taking the advantages of 3D printing to solve the existing problems caused by traditional manufacturing, two proof-of-concept mirror fabrication strategies are investigated in this paper. The First concept is a deformable mirror with embedded actuator supports system to minimise errors caused by the bonding interfaces during mirror assembly. The second concept is the adaption of the Stress Mirror Polishing (SMP) technique to a variety of mirror shapes by implemented a printed thickness distribution on the back side of the mirror. Design investigations and prototypes plans are presented for both studies.
