增材制造 (AM) 也称为 3D 打印，利用数字设计文件逐层构建物体。逐层方法的主要优点是设计空间的增加，这使得工程师和科学家能够创建通过传统减材加工（铣床、钻床和车床）不切实际或不可能的结构和几何形状。增材制造提供的不仅仅是原型解决方案：有多种可用材料（聚合物、金属和陶瓷）；能够创建针对物理环境优化的轻质结构的软件；以及众多提供增材制造服务的机构，其服务与减材加工同等。此外，增材制造还是定制低数量零件的理想方法，这些零件通常是天文仪器的基础。然而，增材制造带来了许多挑战和好处，因此，OPTICON A2IM Cookbook 的目标是为读者提供一个资源，概述增材制造的范围以及如何在天文硬件中采用增材制造，重点是轻质镜子的制造。该食谱是欧盟 H2020 资助的 OPTICON（天文学光学红外协调网络；拨款协议#730890）A2IM（增材天文学集成组件制造；PI H. Schnetler）工作包的开放获取交付成果，于 2021 年 6 月完成。本文将介绍该食谱、其范围和方法，并强调设计和用于天文学和增材制造的轻型镜子所需的范式转变。空间科学。
Additive manufacture (AM), also known as 3D printing, builds an object, layer-by-layer, from a digital design file. The primary advantage of the layer-by-layer approach is the increase in design-space, which enables engineers and scientists to create structures and geometries that would not be practical, or possible, via conventional subtractive machining (mill, drill and lathe). AM provides more than prototyping solutions: there are a broad range of materials available (polymers, metals and ceramics); software capable of creating lightweight structures optimised for the physical environment; and numerous bureaux offering AM as a service on a par with subtractive machining. In addition, AM is an ideal method for bespoke, low-count parts, which are often the foundation of astronomical instrumentation. However, AM offers many challenges as well as benefits and, therefore, the goal of the OPTICON A2IM Cookbook is to provide the reader with a resource that outlines the scope of AM and how to adopt it within astronomical hardware, with an emphasis on the fabrication of lightweight mirrors. The Cookbook was an open access deliverable of the EU H2020 funded OPTICON (Optical Infrared Coordination Network for Astronomy; grant agreement #730890) A2IM (Additive Astronomy Integrated-component Manufacturing; PI H. Schnetler) work package and it was completed in June 2021. This paper will introduce the Cookbook, its scope and methodology, and highlight the paradigm shift required to design and AM lightweight mirrors for astronomy and space-science.
