7. Working principles of the 3D printer
• The 3D printer requires a le containing the three-dimensional data of the object that you wish to print (.stl is a
standard format).
• You can create these les using suitable software or a 3D scanner. You can also download ready-to-use print les
from the Internet to print objects quickly.
• The printer software converts the three-dimensional data into a .gcode le that contains information about the
printed layers and temperatures for the nozzle and other components.
• The .gcode le can be sent to the printer from a computer via the USB port, or you can insert an SD card containing
the le into the printer and use the built-in control panel.
• The 3D printer creates the object layer by layer (by fusing the lament material). The lament material is transported
from the lament spool to the nozzle.
• The lament material is melted in the extruder and applied layer by layer to the print bed via a ne nozzle.
• The print bed moves along the Z axis (up/down), and the extruder moves along the X (left/right) and Y (forwards/
backwards) axes. This allows the printer to create a three-dimensional object by applying the layers horizontally.
A 3D printer is a very complex machine that requires you to congure numerous parameters
according to the 3D printer model, printed object and lament material.
The printing temperature, lament material, print bed calibration settings, size/shape of the printed
object and the surface of the print bed also affect how the printed object adheres to the print bed.
Draughts, grease on the print bed and other factors can also affect the quality and durability of the
printed object.
It is therefore not possible to ensure high-quality prints without testing the parameters in advance.
Change the parameters in small steps to ensure optimal results for your desired application. The
pre-installed print templates on the SD card can be used for reference, but need to be ne-tuned
based on the aforementioned parameters to ensure optimal results.

• Cut the cable ties on both sides using a wire cutter.
• Ensure that no parts are missing or damaged. Do not use the printer if parts are missing or damaged.
11. Assembly
a) Setting up the 3D printer
When choosing a location for the 3D printer, ensure that the power switch is easily accessible so that you
can switch it off quickly in the event of a fault.
Ensure that there is sufcient ventilation around the printer. Do not place the printer on soft surfaces (e.g.
rug or bed). The air must be able to circulate freely and must not be obstructed by other objects. This would
prevent heat from dissipating from the printer and lead to overheating (re hazard).
Place the printer on a stable surface and ensure that it is securely in place. It may cause an injury if it falls
off the surface.
Ensure that the USB and mains cable are not pinched or damaged by sharp edges.
Lay the cables in a place where people will not trip over them or become entangled. This may cause an
injury.
• Place the 3D printer on a dry, level surface that is not sensitive to vibrations.
Anti-slip feet are attached to the bottom of the printer. If necessary, place a protective cover underneath the printer
to prevent the surface from getting scratched.
b) Installation and connection
The mains socket must be close to the printer and easily accessible so that you can quickly
disconnect the printer from the mains in the event of a fault.
Exercise caution when handling the mains cable and connecting it to the mains. Mains voltages
can cause fatal electric shocks.
Before connecting the printer to the mains, check that the voltage stated on the printer matches
the voltage of the mains socket. If not, do not connect the printer to the mains. An incorrect mains
voltage can cause irreparable damage to the printer and endanger the user.

< Pause > Pause the printing process.
< Resume > Resume the printing process.
< Stop >
Stop the printing process. The nozzle and print bed will return to their initial position. The
extruder will start the cooling process. It may take several seconds for the extruder to
stop moving.
< Temp. >
Set the temperature of the nozzle or hot plate.
You can choose a nozzle temperature between 0 and 260 °C.
Do not use the nozzle continuously at 260 °C. Continuously operating the
printer at temperatures above 260 °C signicantly reduces the life span of the
extruder. Allow the printer to cool down before using it again.

The printing speed can be set from 10 to 300 %. The standard setting is 100 %.
The printing speed is set by the "Cura" software when the GCODE le is
generated. The speed option allows you to adjust the speed as a percentage
of the preset speed (e.g. 150 %). For best results, use the "Cura" software to
set the desired speed.
