Abstract
A method of operating a multi-nozzle extruder in an additive manufacturing system enables support structure to be formed while an object is also being formed. The method includes opening more than one nozzle in the multi-nozzle extruder, and operating an actuator with a controller to move the multi-nozzle extruder along a path to form a first group of multiple parallel ribbons of support structure simultaneously with material extruded from the more than one open nozzle.
