Fiber Encapsulation Additive Manufacturing (FEAM), based on material extrusion, produces composite structures by simultaneously co-depositing a matrix material (e.g. a thermoplastic polymer) and a fiber (e.g., a metal wire). A variety of sensors and actuators have already been demonstrated using the technology. Through recent upgrades to the prototype FEAM printer comprising hardware for laser soldering of junctions and hardware for depositing a soft magnetic composite, we have demonstrated the ability to automatically fabricate a solenoid actuator comprising a 3-D coil with dozens of windings and an iron composite plunger in a fully-integrated process occurring within a single machine.
