6. Working Principle of the 3D Printer
For 3D print, first a file is needed that contains the three-dimensional data of the object to be printed (a common format of such a
file is, e.g., a .stl-file).
This file can be produced with the corresponding software or with a 3D-scanner. There are also many printing files already online
that can be downloaded to print an object as quickly as possible.
The actual printer software has the task to render the above three-dimensional file into a file that the printer can print. This is a
file in which the individual print layers, the print temperatures for printing head and heating bed, etc. are specified. The file has
the extension “.gcode”.
This GCODE printing file is sent to the 3D printer either via the USB interface by the computer, or an SD card with the printing file
is put into the card reader and the 3D printer is used in standalone operation.
The 3D printer then prints the print file layer for layer according to the FFF (Fused Filament Fabrication) / FDM (Fused Deposition
Modelling) procedure.
At the actual print, the filament material is transported from the filament roll to the print head (extruder).
In the extruder, the filament material is melted and then applied to the heating plate via a fine extruder nozzle layer by layer.
The heating plate moves in the Y and Z directions, the extruder moves in the X-direction. Thus, all prerequisites to produce a three-
dimensional object by horizontal application of the present layers are created.
A 3D printer is a highly complex device in which many parameters must be set depending on the printer, printed object
and filament material used.
Additionally, the adhesion of the printed object on the printing plate is influenced by printing plate temperature, fila-
ment material, shape of the printed object and surface properties of the printing plate.
Ambience influences such as drafts, grease on the printing plate, etc. also play a role in the quality and adhesion of the
printed object.
For the above reasons, it is not possible to achieve high-quality print results at once and without previous experi-
ments.
Change the adjustable parameters in small steps to achieve the best printing results for your application. The printing
examples enclosed on the SD-card provide references, but must be refined for perfect results depending on the above
parameters.

9. Assembly of the Mechanical Parts
The following chapters refer to the assembly of the 3D printing construction kit, but are also interesting for owners of the ready-
made device as information for later accessory assembly.
If you have purchased the finished device, you can skip the following chapters and continue directly with the chapter “Initial
commissioning”.
a) General Information
Take enough time for the assembly. Hurrying often leads to mistakes that may damage components or ruin the time
benefit by elaborate rework.
The workplace should be suciently large and clean so that the dierent components and assemblies can be put down
and installed easily.
The stainless steel parts of the construction kit are very sensitive to dirt. Wash your hands before installing these parts
and use cotton gloves if necessary. Remove the protective film only directly before assembly.
Always observe the images during assembly. Here, the assembly locations and correct alignment of the components
are shown.
All mechanical components of the construction kit are produced extremely precisely. Never apply any force during as-
sembly. All parts can be assembled without any great application of force. If this is not the case, rethink the assembly
step and reread the corresponding description in these instructions.
When tightening the screws, ensure that you do not tighten them too tightly. Many screws are turned into aluminium
threads and therefore must not be tightened as far as it would be possible, e.g., in steel threads.
Sort the screws by size before assembly. This facilitates assembly, since you do not have to look for individual screws.
For countersunk-head screws, the length (l) is measured with the screw head; for cylinder head screws, the length
measurement takes place without the screw head. The diameter (d) is always measured by the thread.
