Ultimate Guide to Filament Problems in 3D Printer Extruder

3D printing out of Filament silk? These steps teach you to solve quickly!

The Filament of the disc is jammed, which can cause the silk to be impeded?
3D printing out of Filament, why?

No Filament when printing;
Insufficient amount of Filament;
Fault generating;


Once the Filament is not smooth, you need specific analysis of the specific problems, one by one to investigate the reasons:
Is the disc sticking?


Is the print nozzle plugged?

If the print nozzle is blocked, follow these steps:

1. heating print head, from the print head to take out the material (Note: be sure to print the head in the case of heating out of the material, under the cooling state forcibly pull out will lead to more serious congestion);

2. Use a steel wire with a diameter smaller than the nozzle or a minimum six inner angle wrench to clear the nozzle;


3. the nozzle temperature manually raised, manually to the throat extrusion Filament, so that nozzle normal spinning;

4. pull out the Filament, the Filament is inserted into the pipes again, such as Filament melting out, repeated several times until the final Filament smooth (the purpose is to make the semi molten wire residue in nozzle blockage or adhesion out);

If the above method can not be solved, you need to remove the print nozzle:


1. Remove the nozzle and heat the part of the adhesive material in the nozzle with the spray gun. Clean the materials and impurities sticking to the nozzle;

2. after cleaning or replacement nozzle re installed, and if the yarn is not smooth, we should consider whether the need to replace the pipe inside the PTFE tube, if the PTFE tube deformation, it will cause serious plug;

3. reinstall the print nozzle, you can smooth out the Filament;

Alunar 3D Printer Extruder adopts new structure, nozzle is easier to assemble and disassemble, avoid plug problem from the source. In addition to the filament is also very important, good quality filament to a great extent, can avoid this problem.
