SEOUL, Dec. 3 (Korea Bizwire) – The Korea Institute of Machinery & Materials (KIMM) announced Tuesday the development of a groundbreaking 3D printing technology capable of producing high-performance motors for use in robotics, electric vehicles, and mobility devices without the need for traditional molds.
The innovative technology was created in collaboration with the Korea Institute of Materials Science and research teams from Gachon University. It utilizes specialized 3D printing equipment designed for magnetic materials, enabling the precise replication of complex motor structures.
Researchers successfully developed axial flux motors—a type of high-efficiency motor where electromagnetic force aligns parallel to the axis—by overcoming limitations of traditional two-dimensional designs. This was achieved through enhanced material properties and the elimination of conventional mold requirements.
Conventional methods for motor production rely on molds and stacked laminations of electrical steel or powder, which restrict design flexibility, increase costs, and contribute to environmental pollution.
“This 3D printing technology offers greater design freedom to maximize performance while simplifying processes and reducing costs by eliminating the need for molds and complex equipment,” said Ha Tae-ho, lead researcher at KIMM.
The innovation promises to enhance efficiency and sustainability in motor manufacturing, positioning South Korea as a leader in advanced engineering solutions.
