教学目标 Course Objectives

增材制造(Additive Manufacturing，AM)俗称 3D 打印，其融合了计算机辅助设计、材料科学及材料加工成形技术等学科，

以数字模型文件为基础，通过软件与数控系统将专用的材料按照逐层堆积的方法制造出实体物品。这种新的工艺为加工制

造领域提供了新的方法和思路。虽然增材制造的基本原理很简单，但其中的微观机理与传统制造方法大不相同，尤其在金

属增材制造这种急冷急热的极端条件下的凝固情况，更需要考虑的是其亚稳态甚至瞬态的过程，这与传统的金属凝固的稳

态过程完全不同，这是一门全新的科学与技术领域。

本课程从金属液固相转变开始，逐步引导学生学习掌握晶体凝固热力学和动力学原理以及增材制造非平衡条件下的凝固过

程和理论，在此基础上讨论非平衡组织形成机理以及对后续材料工艺和性能的影响，理解增材制造过程中的组织控制理

论、缺陷形成机制和监测技术以及增材制造新金属材料研发技术等。通过该课程学习，期望学生了解和掌握金属增材制造

技术与材料制备技术的理论基础，为学生未来进一步增材制造课程学习研究和工作（学术研究和企业技术开发）打下坚实

基础。

Additive Manufacturing (AM), commonly known as 3D printing, combines computer-aided design, material science and

materials processing technologies. Based on digital model files, the special materials are stacked layer by layer through

software and numerical control system to make parts. This new process provides new methods and ideas for the

manufacturing industry. Although the basic principle of additive manufacturing is very simple, the microscopic mechanism

is quite different from the traditional manufacturing processes, especially in the case of the rapid heating and cooling of

metals during AM processing. More importantly, it is considered to be metastable state or even transient process, which

is completely different from the steady-state processes considered in traditional casting processes. The purpose of this

course is to provide students with a deeper understanding of metal additive manufacturing. After completing this course,

they will have a certain understanding of the micro-mechanism in the process of AM solidification, and cultivate student’s

ability of analyzing problems from steady state to transients in macro to micro scales.
