Abstract
A method of operating an extruder assembly to form a three-dimensional build object forms a build object quickly, with enhanced feature resolution, and with increased structural strength. The method includes positioning with at least one actuator an extruder having at least one opening defining an extrusion area through which build material can be extruded through the at least one opening. The extruder is positioned to cover a first portion of the extrusion area with a portion of an object supported on a build platen and to leave open a second portion of the extrusion area. The method further includes extruding a first continuous ribbon of build material adjacent to the object through the second portion of the extrusion area while moving the extruder along the object with the at least one actuator.
