MIT engineers designed a multimaterial 3D-printing system with four synchronized extrusion tools capable of depositing conductive and magnetic materials layer-by-layer. They demonstrated the platform by producing a fully functional electric linear motor using five materials, requiring only one post-processing step. This process is significantly faster and enabled production onsite, unlike traditional methods that rely on specialized equipment and centralized fabrication.
The printed motor's performance matched or exceeded similar conventionally manufactured models. While the technology promises to democratize customizable electric component manufacturing for robots and vehicles and reduce waste, it remains a prototype requiring further development for widespread adoption beyond research settings.
