A team from MIT has presented an additive manufacturing platform that can produce functional electric motors in a single operation. This system integrates multiple materials, from conductive components to magnetic parts, in a single automated process. The ability to manufacture complex electromechanical devices at the point of use raises changes in production and maintenance models.
Integration of Four Extruders for Specialized Materials 🧲
The platform uses four independent extrusion heads, each dedicated to a material with specific properties: a conductor (silver), a magnetic material (strontium ferrite), a structural polymer, and a soluble support material. The key was to develop compatible printing parameters for all of them, avoiding thermal or chemical interferences. In a test, it manufactured an operational linear motor in three hours, with performance validated in thrust tests.
Goodbye to Logistics, Hello to What if We Reprint It? 🤔
This could redefine the concept of spare parts stock. Instead of storing motors for each machine, a roll of magnetic filament and a digital blueprint will suffice. The next time something fails, the debate won't be Who ordered it? but Who forgot to load the conductive material?. No more waiting months for a shipment; now the wait will be for the printer, with its leisurely three-hour pace, giving you time for a coffee... or three.
