Abstract
A 3D printer spray nozzle includes a feeding pipeline, an extruder located under the feeding pipeline, an external housing and a driving device; wherein the feeding pipeline is embedded in the external housing, the extruder is coaxially fixed under the feeding pipeline, a center of gravity of a cross section area of an inner channel of the feeding pipeline and that of the extruder are located on a same axis which is perpendicular to the cross section area of the inner channel of the feeding pipeline and that of the extruder, the feeding pipeline is driven by the driving device to rotate around the axis relative to the extruder, thereby aiming at different rotation angles, widths of extruding forming areas of the extruder at a same direction are different so as to adjust a cross section area of a sprayed filament.
