A 3D printing smart nozzle

Abstract

The invention discloses an intelligent nozzle of a 3D (Three-Dimensional) printer. The intelligent nozzle of the 3D printer comprises a fixed bracket, a cover plate, a concave bracket, a heat conduction block and a material guide pipe, wherein the cover plate is mounted at the top of the fixed bracket; the concave bracket is mounted at the bottom of the fixed bracket; the heat conduction block is mounted at the bottom of the concave bracket; an extrusion head is arranged at the front end of the material guide pipe; the material guide pipe is vertically arranged in the fixed bracket; the extrusion head is exposed out of the bottom of the heat conduction block; the intelligent nozzle of the 3D printer also comprises at least one heating part and at least one temperature sensing part; the heating part and the temperature sensing part are mounted in the heat conduction block. The extrusion head of the intelligent nozzle comprises the heating part and the temperature sensing part and is capable of accurately controlling the thread extrusion temperature, guaranteeing the smooth thread extrusion and automatically cleaning the nozzle; all circuit lines are fixed in the nozzle, so that the problem that the circuit lines are abraded, broken and cut out in the process of moving the extrusion head is avoided.

Description

technical field [0001] The invention relates to a 3D printer, in particular to a 3D printing intelligent nozzle. Background technique [0002] As one of the core components of the 3D printer, the extrusion nozzle of the 3D printer determines the quality of the molding to a large extent. The smoothness of the filament flowing out of the extruder, the temperature of the filament and the cleanliness of the nozzle directly affect the accuracy of 3D printing. [0003] However, the existing 3D printers cannot achieve the heating and temperature measurement effects of the extrusion nozzle, and the temperature of the extruded filament directly affects the quality of the printed product. Since the temperature of the filament cannot be accurately controlled, it cannot meet the printing accuracy requirements. [0004] The surface of the extrusion head is currently cleaned manually, which is time-consuming and labor-intensive. Since the surface temperature of the nozzle is as high as 1...

Problems solved by technology

[0003] However, the existing 3D printers cannot achieve the heating and temperature measurement effects of the extrusion nozzle, and the temperature of the extruded filament directly affects the quality of the printed product. Since the temperature of the filament cannot be accurately controlled, it cannot meet the printing accuracy requirements

[0004] The surface of the extrusion head is currently cleaned manually, which is time-consuming and labor-intensive. Since the surface temperature of the nozzle is as high as 180 degrees, it is easy to burn the operator accidentally.
