Patent ID: 10894358

Abstract:
An extruder head has an arrangement of multiple nozzles in the faceplate that avoids aligning the multiple nozzles at angular orientations from the 0°-180° axis and 90°-270° axis intersection at the center of the faceplate. The extruder head includes a housing having a faceplate with a plurality of nozzles that are equally spaced from one another when the nozzles are projected onto a first axis in a plane of the faceplate and the nozzles are equally spaced from one another when projected onto a second axis in the plane of the faceplate that is orthogonal to the first axis. Movement of the extruder head along any angular path from the intersection of the first axis and the second axis in the plane of the faceplate enables at least one nozzle in the plurality of nozzles to not be aligned with any other nozzle.
