Abstract:
The present invention relates to a technical field of 3D printing, and more particularly to a 3D printer spray nozzle structure and a method thereof for controlling speed and precision. According to the present invention, a feeding pipeline is embedded in an external shell, the feeding pipeline and an extruder are coaxially connected; the extruder is driven by a driving device, so as to rotate relative to the feeding pipeline. A rotation angle of the extruder relative to the feeding pipeline is controlled by rotation of a motor, for controlling a filament area actually sprayed by the extrude, in such a manner that printing speed and precision is controlled for suiting different requirements of different printing area. The present invention controls the printing speed and precision, for improving overall printing speed with precision requirements satisfied, and is applicable to 3D printer spray nozzle structure and controlling.

Claim (Index 4):
The method, as recited in  claim 2 , wherein when an internal channel cross section shape of the feeding pipeline and an internal channel cross section shape of the extruder are both a triangle with a side length of 3a, the cross section area S of the filament actually sprayed by the extruder is: S = 9 \ue89e 3 4 \ue89e 1 + tan 2 \ue89e \u03b8 2 1 + 3 \ue89e tan \ue89e \u03b8 2 \ue89e a 2 wherein \u03b8 is a motor-driven rotation angle of the extruder.
