Abstract

The invention discloses a caliber self-adjustable 3D (Three Dimensional) printer spraying nozzle. The caliber self-adjustable 3D printer spraying nozzle comprises a spraying nozzle which is fixedly arranged, wherein the spraying nozzle comprises a material guide pipe for conveying consumable items and the spraying nozzle and the material guide pipe are arranged on the same axis; the material guide pipe is in sliding sleeve joint with a material storage pipe and can move along the self-axis of the material guide pipe; the spraying nozzle further comprises an extruding opening outer wall and a flow control body; and the flow control body and an inner wall of the extruding opening outer wall can be switched between a matching state and a releasing state along changes of an extruding amount. According to the caliber self-adjustable 3D printer spraying nozzle, self-adaptive adjustment of a caliber range is carried out according to a flow speed and a flow of the consumable items, and the control precision is high; and the time for printing an object with relatively low precision by a 3D printer can be remarkably shortened.

Description

technical field [0001] The invention relates to a 3D printer, in particular to a 3D printing extrusion head with automatic flow rate variable diameter. Background technique [0002] 3D printing technology brings great convenience to human life. 3D printing technology is widely used in food, construction and medicine. It has great advantages in the manufacture of complex workpieces. Complicated workpieces are manufactured and compared with traditional manufacturing processes, the manufacturing time is short, the manufacturing cost is low, and the manufacturing accuracy is high. [0003] When the existing 3D printing extrusion head prints the workpiece, the extrusion radius of the extrusion port is fixed. When the printing workpiece requires a larger extrusion volume and extrusion radius, the existing extrusion port cannot be adjusted according to the workpiece. It is necessary to change its extrusion amount and extrusion radius. Contents of the invention [0004] In order...
