SECURITY
1. Intended Use
3Dfeedy is designed exclusively for the home user in the hobby and do-it-yourself sector for the
following purposes:
• multi-filament printing
• number of filaments dependent on number of Feedy units; 3Dfeedy intended for 3 filaments.
• compatible filament is dependent on your 3D-printer.
All other applications are expressly excluded and are considered to be non-intended use. The
manufacturer or dealer accepts no liability for injuries, loss or damage caused by non-intended or
incorrect use.
Possible examples of non-intended or incorrect use are:
• use of the 3Dfeedy for purposes other than those for which it is intended;
• failure to observe the safety instructions and warnings, as well as the assembly, operating,
maintenance and cleaning instructions contained in this operating manual;
• failure to observe any accident prevention, occupational health or safety regulations specific
and/ or generally applicable to the use of 3D-printing equipment;
• use of accessories and spare parts not intended for the 3Dfeedy;
• modifications to the 3Dfeedy;
• repair of the 3Dfeedy by someone other than the manufacturer or a specialist;
• commercial, craft or industrial use of 3Dfeedy;
• operation or maintenance of 3Dfeedy by persons who are not familiar with the handling of the
feeder and/or do not understand the associated hazards.
Despite intended use, non-obvious residual risks cannot be completely ruled out.

Preparation 3D-Printer » Disconnect Power Supply
Version 1.0 6 von 25
PREPARATION 3D-PRINTER
The following steps are explained in general, as they are applicable the same way to any 3D-printer.
However, the pictures are shown as an example based on Ultimaker 2+, which makes the individual
steps probably look slightly different.
We cannot give any warranty for your 3D-printer. However, if you follow all the steps carefully
and take care of yourself and your printer, no damage is expected.
As you are installing 3Dfeedy to your 3D-printer, you have to make sure your 3D-printer does
have a CE-Conformity.
1. Disconnect Power Supply
Disconnect your 3D-printer from the power supply.
Failure to follow the instructions for proper set up, use and care for your device can increase the
risk of serious personal injury, death or property damage.
2. Unplug PTFE Tube
• Unplug the PTFE tube from the extruder.
• Unplug the PTFE tube from the printhead.
For unplugging the PTFE tube, usually a release button has to be used.

Preparation 3D-Printer » Remove Extruder
Version 1.0 7 von 25
3. Remove Extruder
• Unscrew the screws of the extruder.
• Remove the extruder.
i It could look different with your 3D-printer to the visualization shown above.
4. Remove Drive Gear
• Remove the drive gear from the extruder drive motor.
In some cases, an additional stud screw has to be removed or loosened.
i It could look different with your 3D-printer to the visualization shown above.
i Sometimes, the drive gear already fits to the drive gear of 3Dfeedy (e.g. Ultimaker 2+), which
makes it unnecessary to change it. You can check this by comparing the additional drive gear
from the box with the mounted one of your 3D-printer.
If the drive gear is tight fit to the extruder drive motor, do not damage the extruder drive motor.
Please purchase a new extruder drive motor with equal settings of the existing extruder drive
motor.

Make sure the 3D-printer is disconnected from the power supply.
i If it is necessary for dismounting the extruder drive motor, unplug the extruder drive motor cable
temporarily from the mainboard of your 3D-printer. Remember the plug position on your
mainboard.
