在这篇论文中，我们正在探索3D打印在天文学镜子制造中的可能性。利用3D打印技术的优势，解决传统制造方法存在的问题，研究了两种概念验证的镜面制造策略。第一个概念是一个可变形的镜面，内置执行器支撑系统，以最大限度地减少镜面组装过程中由粘合接口引起的误差。第二个概念是通过在镜子背面实现印刷厚度分布，使应力镜抛光（SMP）技术适应各种镜子形状。为这两项研究提出了设计调查和原型计划。
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.
