Magreesource (2020)
法国初创公司MagREEsource近日宣布，其首条短循环回收与增材制造中试生产线已正式投运。该公司正着力开发制造能力，旨在生产采用4D打印技术的高性能烧结磁体。
这一突破源于格勒诺布尔尼尔研究所（CNRS）长达30年的研发积累，相关技术已获得专利保护。其核心在于利用氢与稀土基材料的选择性相互作用，实现了稀土元素的高效分离与回收。
通过整合短循环回收与增材制造工艺，MagREEsource致力于构建从废旧磁体中回收稀土、并直接将其用于打印新磁体的闭环生产体系。该技术路线有望减少对稀土初级开采的依赖，提升战略资源供应链的韧性。
MagREEsource has launched its first pilot line for short-loop recycling and additive manufacturing of rare earth magnets. The startup is building production capabilities to manufacture high-performance, 4D-printed sintered magnets, leveraging patented technologies developed from 30 years of R&D at the Neel Institute - CNRS.
The core innovation stems from research on the selective interactions of hydrogen with rare earth-based materials. This scientific foundation enables MagREEsource's proprietary processes for both recycling end-of-life magnets and producing new ones via additive manufacturing. The pilot line represents a critical step in scaling these technologies, aiming to create a circular, domestic supply chain for strategic permanent magnets used in electric vehicles, wind turbines, and electronics.
MagREEsource crée sa première ligne pilote recyclage à boucle courte et de fabrication additive. La start-up développe des capacités de fabrication pour produire des aimants frittés imprimés en 4D et haute performance. 30 ans de R&D à l’Institut Neel - CNRS ont conduit à des technologies brevetées dans les interactions sélectives de l’hydrogène avec des matériaux à base de terres rares.
