The forming mode of present 3D printer includes: fused Deposition (FDM), selective Laser Sintering (SLS), and Stereolithography (SLA), among others.

The nozzle part used by the FDM3D printer at present mainly comprises 4 parts, namely a nozzle, a throat, a heating block and a radiating block, wherein the first three parts are matched by threads, namely the heating block is an internal thread, the nozzle and the throat are external threads, and the nozzle is sealed with the throat by connecting the nozzle with the internal thread of the heating block, so that two end faces are attached to each other. Such hard-to-hard sealing is prone to incomplete sealing due to poor part machining accuracy or operator installation negligence, resulting in material leakage. After the three parts are assembled, the throat pipe is fixed on the radiating block through threads or a machine-meter screw, and the throat pipe is metal and has good heat conduction performance, so that a large amount of heat can be guided to the radiating block, a large amount of heat is lost, once the radiating block can not dissipate the heat, the material is easily blocked in the throat pipe, and the printing can not be normally carried out.

The above disadvantages need to be improved.
