Predictive flow control responses in an additive manufacturing system

An additive manufacturing system includes an extruder having a motor and a pressure sensor. A filter receives speed values for the motor and generates a predicted pressure value from the speed values. A response threshold module sets a response threshold pressure value based on the predicted pressur...

Zusammenfassung:	An additive manufacturing system includes an extruder having a motor and a pressure sensor. A filter receives speed values for the motor and generates a predicted pressure value from the speed values. A response threshold module sets a response threshold pressure value based on the predicted pressure value such that when the response threshold pressure value is between a pressure value from the pressure sensor and the predicted pressure value, a response is executed.
