摘要:: 基于材料逐层堆积制造的增材制造技术将传统的三维制造降为二维制造，突破了传统制造方法的约束和限制，特别适合制造具有复杂内置随形冷却流道的模具钢。增材制造模具钢专用粉末材料、增材制造工艺及其性能等是影响增材制造模具钢应用的主要因素。重点综述了增材制造模具钢粉末材料的设计与制备研究进展，探讨了几种典型的模具钢增材制造工艺及其性能，在此基础上，介绍了增材制造技术在模具钢领域的应用实例及现状，以期为增材制造模具钢的深入研究提供借鉴。

Abstract:: The additive manufacturing (AM) technology based on layer-by-layer stacking reduces the traditional 3D manufacturing to 2D manufacturing, and breaks through the constraints and limitations of traditional manufacturing methods, especially is suitable for manufacturing mold steel with complex comformal cooling channels. AM mold steel materials, AM process and properties are the main factors affecting the application of AM mold steel. For this reason, this paper summarizes the research progress of material design and preparation of AM mold steel powder materials, discusses several typical manufacturing processes for mold steel and their performance. Finally, this paper introduces the application example and present situation of AM mold steel. This paper may supply guidance for the further research of AM mold steel.
