PARTS, SPECIFICATIONS AND OPERATION OF YOUR WITBOX
This section of the manual will help you identify the main parts of your Witbox and
learn how they work.
Extruder
As we mentioned in the introduction, the Witbox uses the
Fused Filament Fabrication (FFF) method, which consists
of building an object by adding layers of melted polymer
filament on top of one another.
In order to do this, your printer contains a very important
unit called the extruder
(fig. 5.1), which is responsible for
the entirety of the extrusion process.
The extruder is comprised of the following components (fig. 5.2 and fig. 5.3):
• Extruder motor:
this provides the necessary motive power to draw the filament
from the spool and transport it to the Hot-End, where it is melted at high
temperature and deposited in layers onto the print base. The Witbox uses a 12
V Nema 17 DC stepper motor with a torque rating of 4000 g/cm.
• Extruder body: as the name suggests, this is the extruder’s body and houses all
the other parts. It is made of 6082-grade aluminium.
• Pulley: this is connected to the extruder motor. The mechanical operation of
its teeth and its rotation in time with the motor serve to draw the filament
towards the Hot-End.
• Extruder lever: with the help of the spring located at the end, this lever presses
the filament against the pulley, thereby aiding its passage towards the Hot-End.
It is made of 6082-grade aluminium.
• Fan and heat sink: these are attached to the extruder body and help keep it
cool.
• Fan and blower: these are used under certain circumstances to cool the
extruded polymer.
• Tube connector: this is where the polymer enters the extruder.
