增材制造（AM），也被称为“3D打印”，已经从概念和原型转变为零件对零件的替换——现在转变为创建只能使用AM制造的零件几何图形。随着各种移动原始设备制造商开始在其产品中引入AM零件，AM零件制造的内包和外包之间的问题已经浮出水面。与使用其他技术制造的零件一样，AM零件可能需要大量的后处理操作。因此，随着AM供应链的发展，AM零件制造及其后处理的采购成为一个尚未解决的重要问题。内包和外包添加剂制造的未解决方面讨论了方法和贸易- 针对多个场景，包括金属和聚合物技术和组件，生产硬件的不同采购选项。

Additive manufacturing (AM), also known as "3D printing," has transitioned from concepts and prototypes to part-for-part substitution--and now to the creation of part geometries that can only be made using AM. As a wide range of mobility OEMs begin to introduce AM parts into their products, the question between insourcing and outsourcing the manufacturing of AM parts has surfaced. Just like parts made using other technologies, AM parts can require significant post-processing operations. Therefore, as AM supply chains begin to develop, the sourcing of AM part building and their post-processing becomes an unsettled and important issue.Unsettled Aspects of Insourcing and Outsourcing Additive Manufacturingdiscusses the approaches and trade-offs of the different sourcing options for production hardware for multiple scenarios, including both metallic and polymer technologies and components.
