South Korea innovates magnetic 3D printing technology for manufacturing high-performance motors for future industries.
Researchers from Korea Institute of Machinery & Materials (KIMM), South Korea have developed an innovative magnetic 3D printing technology for manufacturing high-performance motors. This innovation allows for creating intricate motor designs without relying on traditional moulds, maintaining higher efficiency and performance. Successfully tested on modern motors, this development is poised to improve robotics, mobility, and industrial applications.
A research collaboration led by Dr Taeho Ha, principal researcher, department of 3D printing, research institute of autonomous manufacturing, KIMM in partnership with experts from the Korea Institute of Materials Science and Gachon University, has delivered a comprehensive solution. This includes specialised designs, materials, processes, and equipment tailored to optimise magnetic material properties for motors. “This magnetic 3D printing technology represents an innovative leap beyond traditional manufacturing methods,” Dr Ha noted, highlighting its significance.
Central to this innovation is the development of advanced 3D printing equipment designed to improve magnetic material performance. By eliminating mould dependency, the technology surpasses conventional limitations in motor design and efficiency. A notable achievement is the creation of a 500W axial flux motor, featuring an output density surpassing 2.0kW/L. These motors, ideal for robotics and electric vehicles, deliver superior torque and power within compact spaces. Industries like robotics, healthcare, electric mobility, and even defence are expected to benefit significantly, as they demand compact, high-performance motors capable of meeting specific operational needs.
Traditional motor manufacturing methods, which rely on electrical steel laminations and powder formations, are often constrained by design limitations, high costs, and material waste. KIMM’s technology overcomes these challenges, offering a sustainable alternative that reduces environmental impact while enhancing performance.
The versatility of magnetic 3D printing has broad implications for industries requiring high-performance motors, including medical devices, electric mobility, and robotics. By simplifying production processes and enabling cost-effective small-batch manufacturing, the innovation supports the growing demand for customised, efficient solutions.
Looking ahead, Dr Ha emphasised plans to integrate this advancement with high-functional material technologies, opening doors to more complex industrial applications. This pioneering work underscores South Korea’s leadership in shaping the future of motor manufacturing.
