近年来，加法制造或3D打印已被广泛用于制造原型和最终用途部件。因为零件是以一层一层的方式制造的，所以附加制造的灵活性是无与伦比的，并打开了设计空间，使底切和内部通道等特征在传统的减法制造的零件上无法存在。这种灵活性也可用于光学应用。本文概述了目前在Optimax光学制造过程中使用3D打印的一些情况。使用了几种材料和添加剂技术，包括通过熔融沉积建模的聚合物打印，它通过以LayerWise方式沉积软化的热塑性纤维来制造部件。还将讨论利用光固化光致聚合物树脂层的立体光刻技术。这些技术用于制造功能原型、夹具、密封外壳和其他部件。此外，由于有可能制造热稳定的光学机械组装框架和功能光学元件，因此将讨论通过选择性激光熔化的金属印刷，其使用激光将金属粉末层熔化成致密固体。将显示几个添加制造的光学部件的实例。
Additive manufacturing, or 3D printing, has become widely used in recent years for the creation of both prototype and end-use parts. Because the parts are created in a layer-by-layer manner, the flexibility of additive manufacturing is unparalleled and has opened the design space to enable features like undercuts and internal channels which cannot exist on traditional, subtractively manufactured parts. This flexibility can also be leveraged for optical applications. This paper outlines some of the current uses of 3D printing in the optical manufacturing process at Optimax. Several materials and additive technologies are utilized, including polymer printing through fused deposition modeling, which creates parts by depositing a softened thermoplastic filament in a layerwise fashion. Stereolithography, which uses light to cure layers of a photopolymer resin, will also be discussed. These technologies are used to manufacture functional prototypes, fixtures, sealed housings, and other components. Additionally, metal printing through selective laser melting, which uses a laser to melt metal powder layers into a dense solid, will be discussed due to the potential to manufacture thermally stable opticalmechanical assembly frameworks and functional optics. Examples of several additively manufactured optical components will be shown.
