MULTI-NOZZLE EXTRUDER AND METHOD FOR OPERATING A MULTI-NOZZLE EXTRUDER DURING ADDITIVE MANUFACTURING

An additive manufacturing system has a controller configured to operate a spool valve to open and close nozzles in a multi-nozzle extruder while the extruder moves in an X-Y plane and rotates about an axis perpendicular to the XY plane to form swaths in the X-Y plane. The controller operates one act...

Zusammenfassung:An additive manufacturing system has a controller configured to operate a spool valve to open and close nozzles in a multi-nozzle extruder while the extruder moves in an X-Y plane and rotates about an axis perpendicular to the XY plane to form swaths in the X-Y plane. The controller operates one actuator to rotate the multi-nozzle extruder so a longitudinal axis of a nozzle array in the extruder remains perpendicular to a movement path for the extruder and to operate another actuator to move a cylindrical member of the spool valve.
