MIT Develops 3D-Printing Platform for Rapid Production of Complex Electric Motors
MIT researchers have created a 3D-printing system that fabricates complex electric machines, including linear motors, in hours using multiple materials. This system integrates conductive and magnetic substances in one automated process, reducing reliance on traditional manufacturing methods. A retrofitted printer with four extrusion tools allows for diverse material usage, enabling the production of fully operational motors within approximately three hours at low material costs. The platform may lead to on-site customization of electronic components for various applications.

MIT has developed a 3D-printing system capable of producing complex electric machines, including linear motors, in just hours. By integrating multiple materials—conductive and magnetic—into a single automated process, the platform addresses the limitations of traditional manufacturing, which often involves lengthy supply chains.
The system uses a retrofitted printer with four distinct extrusion tools that can print layer by layer with various feedstocks. An electric linear motor was printed in about three hours and demonstrated performance on par with traditional methods.
Material costs for the devices are around 50 cents. This technology could enable on-site production of customized electronic components for applications in robotics, vehicles, and medical devices, potentially reshaping hardware production.
