MIT Researchers Achieve Breakthrough in 3D Printing of Electromagnets

Researchers at the Massachusetts Institute of Technology (MIT) have achieved a breakthrough that could transform electronics production. Their successful 3D printing of three-dimensional solenoids represents a significant leap forward in electronics manufacturing. Solenoids, comprised of a coil of wire wound around a magnetic core, serve as indispensable components in a myriad of electronic applications. From critical medical devices like dialysis machines and respirators to everyday household appliances such as washing machines and dishwashers, solenoids play a vital role in converting electrical energy into mechanical work. Traditionally, manufacturing solenoids has required complex techniques.

The development of fully 3D-manufactured electronic devices currently poses considerable challenges. However, ongoing research marks a progression towards more economical and less wasteful production techniques. These improvements could be used across many industries, with use even in space.

3D Printed Electromagnets

Traditional manufacture of solenoids involves the complex assembly of different materials, often limiting the size and shape of the parts. The use of 3D printing, however, offers the possibility of overcoming these constraints. MIT researchers, led by Luis Fernando Velásquez-García, have solved the problems associated with material compatibility by adapting their multi-material 3D printer to superimpose three different materials: a dielectric material serving as an insulator, a conductive material forming the electrical coil, and a soft magnetic material making up the core. This adaptation facilitated the production of compact, single-piece solenoids, eliminating the potential for assembly errors.
