“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.” Within limits. It is not a fix all, at least in the near term. The printers have been known swing out of specs too far to recover the part(s). PrintRite3D and other methods have a long way to go before the AI algorithms used to provide the ability to save a print in some cases. In order it to be considered a reasonable investment the success rate has to exceed the cost of the close loop - the average parts lost. Just because something becomes automatic doesn’t mean it is worth the cost.
