【摘要】 传统加工方法难以精确控制各材料分布，只能制备材料分布比较简单的零件，异质材料零件3D打印技术具有材料、结构和功能并行设计与制造的特点，能够实现多种材料的可控定量按需打印，制作出不同组分和分布的多材料异质零件，在航空航天、特种工业、医学工程等领域具有广阔的应用前景，成为国内外3D打印领域的研究热点。介绍了多材料零件3D打印成形工艺技术现状及特点。更多还原

【Abstract】 Conventional processing methods are difficult to precisely control the distribution of each material, and only parts with relatively simple material distribution can be prepared. It needs to be printed to produce multi-material heterogeneous parts with different components and distributions, which has broad application prospects in aerospace, special industry, medical engineering and other fields, and has become a research hotspot in the field of 3 D printing at home and abroad. The current situation and characteristics of 3 D printing forming technology for multi-material parts are introduced.更多还原
