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 three­dimensional 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 ready­made 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

For countersunk-head screws, the length (l) is measured with the screw head; for cylinder head screws, the length

threads and therefore must not be tightened as far as it would be possible, e.g., in steel threads. A table with the re­commended tightening torques of the screws can be found in the appendix of these instructions.

Sort the screws by size before assembly. This facilitates assembly, since you do not have to look for individual screws.

measurement takes place without the screw head. The diameter (d) is always measured by the thread.

Push the belt tensioner assembly into the intended section of
the Y-plate and turn the screw into the belt tensioner.
The ball bearings must point to the grooved side of the Y-plate
and the bore in the belt tensioner must be on the right (see
figure).

1x Y-plate
1x guide rails
6x cylinder head screws M4x12

24

Insert the guide rail into the middle groove of the Y-plate and
attach it with the screws.
The imprinted arrows on the guide rail must point to the plate
centre.

Push the guide carriage onto the guide rail

The assembly aid (plastic part in the guide of the guide carriage) must never be removed before pushing on the guide

carriage, since the gearing balls will fall out of the carriage otherwise. This would be irreparable.

This also applies when the guide carriage is pushed from the guide rail after assembly. For reasons of safety, the guide

carriage should be secured, e.g. with adhesive tape before further installation.

The guide carriage has a polished area on one side (see arrow in the figure on the lower left). Turn the guide carriage

so that the arrows on the guide rails point towards the ground area of the guide carriage before pushing it on.

1x Y-plate
1x guide carriage complete with assembly aid

Carefully push the guide carriage onto the guide rail and push
the assembly aid (plastic part) from the guide carriage while
doing so.

Glue connection of the heating plate.

1x ceramics plate
1x heating
4x spacer bolts

Plug the spacer bolts with the thread bores to the bottom of

the ceramics plate (side with tissue structure) and provision

ally fasten with 4 screws.

Caution: Only tighten the screws slightly since there is the
danger that the ceramics plate will break otherwise.

Check the alignment of the heating by pushing the heating

across the spacer bolts. The heating must then be supported

fold-free with the side with the protection foil against the bot­tom of the ceramics plate and must not protrude at the edges.
Clear the bottom of the ceramics plate of dust and grease with

a rag and solvent.

Then remove the protective foil from the heating and finally

glue the heating to the bottom of the ceramics plate without

blisters.

Application of the toothed belt

1x undertable holder from the previous step
1x toothed belt 675 mm

Caution:
The toothed belt must not be tensioned too strongly. If the belt
tensioner bends, the belt tension must be reduced under all
circumstances.
A method for more precise setting of the belt tension is found
in the chapter „Maintenance“.

Assembly of the undertable

Insert toothed belt into the belt tappet angle as shown on the
left.
Relieve belt tensioners entirely.
Turn the undertable holder and put the toothed belt onto pinion
and belt tensioner as shown.
The undertable holder is only placed on the guide carriage
here (do not screw on yet).
Tension toothed belt by turning the belt tensioner screw until it
can still easily be turned by 180° with two fingers.
