添加剂制造（AM），也称为“3D打印”，现在提供了从零件设计到制造和服务的几乎全数字化链的能力。这种“数字线程”可以在改进设计、工艺、材料、操作以及以最大化安全性、最小化成本和停机时间的方式预测故障的能力方面带来巨大的好处。加法制造中数字线程的未解决方面讨论了AM和移动行业中的数字线程之间的相互作用，潜在的收益和成本，组合有用需要克服的障碍，以及组织如何回答这些问题，以确定组合的范围和收益。

Additive manufacturing (AM), also known as "3D printing," now provides the ability to have an almost fully digital chain from part design through manufacture and service. This "digital thread" can bring great benefits in improving designs, processes, materials, operations, and the ability to predict failure in a way that maximizes safety and minimizes cost and downtime.Unsettled Aspects of the Digital Thread in Additive Manufacturingdiscusses what the interplay between AM and a digital thread in the mobility industry would look like, the potential benefits and costs, the hurdles that need to be overcome for the combination to be useful, and how an organization can answer these questions to scope and benefit from the combination.
