喷气发动机部件的增材设计（AD）和增材制造（AM）将彻底改变传统的航空航天工业。增材设计的独特性开创了喷气发动机设计和制造的新方向，比如梯度材料和微观结构。工程师已经从传统方法和技术的诸多限制中解放出来。增材制造过程最重要的特征之一是其可以确保零件的一致性，因为它始于点，继而到线和层面，直至整个部件完成。设计和制造之间的协调是空气动力学、热力学、结构整合、传热、材料开发和加工等方面取得成功的关键。工程师必须改变设计零件的方式，因为他们要从传统的'减材'方法转移到'增材'的新方法来制造零件。增材设计与增材制造设计不一样。我们需要一种新方法和新工具来协助这种新的设计和制方式。本文详细讨论了增材设计与增材制造中的需求，以及如何解决当前的问题。

The additive design (AD) and additive manufacturing (AM) of jet engine parts will revolutionize the traditional aerospace industry. The unique characteristics of AM, such as gradient materials and micro-structures, have opened up a new direction in jet engine design and manufacturing. Engineers have been liberated from many constraints associated with traditional methodologies and technologies. One of the most significant features of the AM process is that it can ensure the consistency of parts because it starts from point(s), continues to line(s) and layer(s), and ends with the competed part. Collaboration between design and manufacturing is the key to success in fields including aerodynamics, thermodynamics, structural integration, heat transfer, material development, and machining. Engineers must change the way they design a part, as they shift from the traditional method of 'subtracting material' to the new method of 'adding material' in order to manufacture a part. AD is not the same as designing for AM. A new method and new tools are required to assist with this new way of designing and manufacturing. This paper discusses in detail what is required in AD and AM, and how current problems can be solved.
