Problems solved by technology

[0004] However, at present, many fused deposition modeling 3D printers are prone to problems such as poor filament discharge and nozzle clogging during the printing process. The wire feeding resistance is too large, which eventually leads to abnormal wire output from the nozzle

Abstract

The invention discloses a 3D printer nozzle. The 3D printer nozzle comprises a substrate, a heat dissipating block, an air cooling system and at least one molten wire outlet module; the heat dissipating block is mounted under the substrate; the upper part of the molten wire outlet module is connected with the substrate, and the middle part is connected with the heat dissipating block; and the aircooling system is mounted on the substrate for cooling the heat dissipating block and the molten wire outlet module. The molten wire outlet module is cooled through the heat dissipating block, and theheat transfer is accelerated through the air cooling system, so that the early softening of wires can be effectively prevented, the wire feeding resistance of a nozzle can be reduced, and the blockage risk of the nozzle is reduced.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a nozzle of a 3D printer. Background technique [0002] 3D printing technology is a kind of rapid prototyping technology. It is based on digital model files and constructs objects by stacking molding materials layer by layer according to the program. Fused deposition modeling technology (FDM technology) is a 3D printing technology that is widely used at present. It uses high temperature to melt thermoplastic materials into a molten state, extrudes through the printing head and solidifies, and finally stacks them in three-dimensional space to form a three-dimensional object. [0003] As one of the core components of 3D printing, the performance and reliability of the print head are crucial to the effect of 3D printing. A well-designed print head can not only improve the surface quality and molding accuracy of sample printing, but also can greatly Greatly improve the stability...
