Abstract

The invention relates to an integrated 3D (three-dimensional) printer extruding nozzle belonging to the technical field of 3D printing. The integrated 3D printer extruding nozzle is provided with a printed circuit board, wherein a heating module outgoing wire is arranged at the top end of a fixed bracket, the printed circuit board supports against the top end of the fixed bracket, a compression joint contact of a heating module control circuit is in contact and in circuit connection with the heating module outgoing wire, therefore, the length of the heating module outgoing wire can be effectively shortened, and the outgoing wire is positioned inside the extruding nozzle, thus the problems of bending, abrading, open circuit, even short circuit and the like possibly caused in the outgoing wire in a process of moving the extruding nozzle are provided; furthermore, a temperature measuring signal amplifying circuit is arranged in the printed circuit board, thus signal attenuation is reduced, the accuracy of measuring and controlling temperature of an extruded silk material is ensured, and the precision of 3D printing is ensured. Meanwhile, the integrated 3D printer extruding nozzle provided by the invention is simple in structure, low in use and maintenance cost and wide in application range.

Description

technical field

[0001] The invention relates to the technical field of 3D printing, in particular to the technical field of the structure of a 3D printer nozzle, and in particular to an integrated 3D printer extrusion nozzle. Background technique

[0002] The extrusion nozzle of the 3D printer is a key component of the 3D printer's walking mechanism. How to control the temperature of the extruded filament during extrusion directly affects the accuracy of 3D printing. Therefore, existing 3D printers usually add a heating device and a temperature measuring device to the extrusion nozzle, and adjust the extrusion temperature of the extruded filament through an external control system to ensure that the printing accuracy can meet the requirements.

[0003] Since the heating device and the temperature measuring device are fixed on the extrusion nozzle, as part of the traveling mechanism, they must move with the extrusion nozzle during the printing process, and the leads of the h...
