اکسترودر MK8 پرینتر سه بعدی با نازل 0.4 میلی متری

Description:
This is an MK8 extruder, which features outstanding quality and ensures better performance for 3D printers. Compared with the previous version, there are some differences in the design of this new extruder. The feeding device of this MK8 extruder uses a double “V” design which can ensure stable and constant feeding, and such design is much more convenient for you to load the filament right to the end of the barrel. The heat-resisting PTFE tube inside the barrel ensures fluent feeding and helps avoid blocking problems thanks to its self-lubricity. The brass nozzle ensures accurate extrusion, realizing an excellent printing effect.
The 3D extruder is the part of the 3D printer that ejects material in the liquid or semi-liquid form in order to deposit it in successive layers within the 3D printing volume. In some cases, the extruder serves only to deposit a bonding agent used to solidify a material that is originally in powder form. Let’s discover the function of the 3D printer extruder, a little but essential part, required for some additive manufacturing processes.
There is not a single extruder type. Your choice will depend on the kind of 3D printer that you have, on the materials that you will use, and on the printing speed and accuracy that you need.
There are two different possibilities: Direct or Bowden extruders. The nature of your projects will determine which extruder you need to use. First, all extruders have motors, but there are also geared extruders to control your print speed. It is not essential, but it can help you to customize your setups in order to improve your print quality.
