Paullee,
Right now, in the metal AM space, sensors inside the printers can see when the printers' function is wandering off track from what is known to be proper. But the information gained from the sensors isn't used to make any real-time changes to the printer function to bring it back in line. Currently the sensors only output data to humans. Closed loop is where the sensors output data, in real-time, back to the printer to automatically cause the printer to change what it is doing to bring everything back to proper function.

All the best,
Silversmith
