摘要
永磁材料已广泛应用于国民经济与国防军工等重要领域,其传统制备过程多采用烧结、铸造等方式进行,工艺流程长且生产成本高。3D打印技术作为一种革命性的新兴生产手段,极大拓展了三维部件的设计及制造自由度,因具有能够生产制备形状复杂的工件的优势,已广泛应用于结构材料的生产制备过程。近年来,3D打印技术呈现向功能材料方向发展的趋势,其在制备永磁材料方面的应用主要包括熔融沉积(FDM)、粘结剂喷射(BJ)、基于激光粉末床熔融的选择性激光熔融(SLM)以及选择性激光烧结(SLS)等技术。综述了3D打印永磁材料研究现状,主要包括Al-Ni-Co永磁体、Mn-Al合金、Sm-Co永磁体和Nd-Fe-B永磁体,并对其未来发展方向进行了展望。
Permanent magnetic materials have been widely used in the fields of national economy, national defense and military industry and other fields, whose traditional preparation process used to be sintering, casting and so on. The process is long and the production cost is high. 3 D printing technology, as a revolutionary means of production, has greatly expanded the freedom of design and manufacturing of three-dimensional components. Because of its advantages in producing and preparing workpieces with complex shapes, 3 D printing technology has been widely used in the production and preparation of structural materials. In recent years, it has been developing towards functional materials. Currently, the commonly used technologies for 3 D printing of permanent magnet materials are mainly fused deposition modeling(FDM), binder jetting(BJ), selective laser melting(SLM) and selective laser sintering(SLS). The research status of 3 D printing of permanent magnet materials is reviewed, mainly including Al-Ni-Co permanent magnets, Mn-Al alloys, Sm-Co permanent magnets and Nd-Fe-B permanent magnets. Meanwhile, the prospect of 3 D printing of permanent magnet materials was also made.
