5 First print
This chapter covers the procedure required to start a print job.
WARNING
The machine needs to be used in well ventilated areas only. Fumes that can occur during the
printing process are material dependent and, especially in case of insufficient ventilation, have to
be extracted.
WARNING
The printer is to be used with a closed cover only. The dddrop printer contains hot surfaces and
the moving parts can lead to injuries. Never reach into the printer when in use.
Always use the printer with the smart module (the touchscreen in front of the printer, or with
smartphone/desktop/tablet) or with the on-off switch on the back of the printer to control the
print job.
Let the printer cool down for at least 10 minutes before opening the cover and reaching into the
printer.
When opening and closing the cover there is a chance of pinching. Always use two hands when
opening or closing the cover. Make sure the cover hinge is in lock position when opened and that
the cover is in positioning hooks when closed.
5.1 Preparation of material
NOTE: For changing filament, go to the Tool tab and follow the instructions at ‘Change Filament’.
Remove the cover from the Filament Management Module at the back of the printer. The general
preparation is given below.
1. Place filament (1.75mm) at the back of the printer on the filament reel brackets. Check that
the filament is correctly wound on the reel and not in a loop which may block the material
supply resulting in a failed print.
2. Feed the filament through the Filament Management Module to the quick connector and
metal curved tube.
3. Go to the printer head and press the lever of the spring-loaded idler wheel free of the driven
wheel and feed the filament through the cooler all the way into the nozzle. The front fan
assembly can be moved out of the way for better visibility.
Feed until the extruder tip is reached and release the spring-loaded lever, allowing the idle
wheel to drive the filament into the driven wheel.
4. Place the curved tube trough the lever into the bearing.
5. Check the material and material choice of the generated file.
15
EN 190524
WARNING
Failure to remove ALL material of a previous build from the heated bed or a badly adjusted heated
bed can cause a collision and damage machine components.
5.2 Preparing heated bed
1. Clean the heated bed from residue of other prints.
2. Empty the container (see 6.2) and clean the brush (see 6.3).
3. Clean the heated bed.
4. Level the bed with the ‘Bed levelling tool’ in the Tool tab.
5. Turn the printer ON by switching the switch on the back of the printer to the ‘I’ position and
wait for the printer to be initialized.
WARNING
The machine contains hot and moving parts. It is strongly advised to only print with cover closed.
The machine can be stopped AT ANY TIME in case of an emergency by switching the power OFF or
disconnecting the power cord.
5.3 Start Print
1. Check if the container is empty and the brush and heated bed have been cleaned.
2. Check if the cover is correctly closed.
3. Select in the ‘File tab’ the Gcode you want to print and confirm this code by pressing on the
checkmark. The printer will be started automatically. In the Status tab the process of the
print can be followed.
5.4 Taking out the printed model
1. Before opening the cover: Check if the printer is ready. The status bar should display print
finished and the total print time is given. The extruder is in its XY home position and the set
temperatures are in cooldown mode.
2. Before opening the cover: Check if the printer is cooled down. The actual temperatures of
the nozzles and heated bed are given in the ‘Status tab’.
3. Open the cover with both hands and check that the hinge is in lock position.
4. Take out the printed model. When it seems to be stuck, the heated bed is probably still too
hot to take out the product. Allow the bed to cool; the product will automatically become
free. Be careful when using spatula or other tools to remove the product. Use protective
clothing (e.g. gloves, safety glasses etc.)!
5. Empty the container and clean the bed so it’s ready for the next print.
6. Turn OFF the printer by switching the power switch to the O position.

EN 190524
6 Maintenance
The dddrop printer is calibrated in order to make a quick start possible. If it however requires
recalibration or maintenance, an overview is given of the steps involved.
Clean the printer externally with a damp cloth. The internals can be cleaned carefully with a vacuum
cleaner.
WARNING
Failure to incorrectly, inaccurately or incompletely follow the calibration procedure will reduce
print quality.
WARNING
Linear guides and the acme threaded rod are greased. Make sure not to contact the grease as it
may work irritating and will stain cloths.
WARNING
Only use the supplied power cable when connecting your printer to the mains. Use a wall socket
with earth pins. Make sure that during maintenance the power supply is switched OFF and the
power cable is disconnected.
Make sure that before connecting the power cable to the mains the power switch is switched to
the OFF position (O).
The machine contains hot and moving parts. It is strongly advised to only print with cover closed.
The machine can be stopped AT ANY TIME in case of an emergency by switching the power OFF or
disconnecting the power cord.
17
EN 190524
6.1 Adjusting heated bed
Goal: the heated bed is to be parallel with the path of the extruder and the distance between the
heated bed and the extruder is equal to 0.1mm. This can be done with the tool ‘Bed Levelling’ in the
tool tab.
1. Go to the Tool tab and select ‘Bed Levelling’.
2. Follow the procedure which is shown on the screen.
Hint: The adjustments knobs moves the bed up or down. See figure 11.
Figure 11. Adjustment knobs moving the bed up (left) and moving the bed down (right)
6.2 Empty the container
The dddrop printers are equipped with a container on the front of the build volume. This container
catches material that needs to be extruded in order to initiate extruder flow. The container is
magnetically mounted to the brush bracket. The container also has two cut-outs to create room for
the fastener items of the brush, also functioning as a vertical block for the container.
1. Check that the printer is not busy but stationary (no print job running). Check that the
printer is cooled down.
2. Open the cover and check that the hinge is in locking position.
3. Take the container in one hand and the bracket in the other. A light pull towards the
operator separates the container from the bracket.
4. Empty the container.
5. Place the empty container back on the bracket. Ensure contact of the magnets with the
metal and position the cut-outs over the fasteners.
6. Close the cover.
6.3 Cleaning the brush
The dddrop 3D printers are equipped with a brush on the front of the build volume. This brush
cleans the nozzle from material that needs to be extruded in order to initiate extruder flow. A clean
brush is of interest in order to get the best print results.
1. Check that the printer is not busy but stationary (no print job running). Check that the
printer is cooled down.
2. Open the cover and check that the hinge is in locking position.
3. Remove any material residue from the brush.
4. Close the cover.

7 Safety and Conformity
7.1 Electromagnetic compatibility (EMC)
This product may cause radio interference which may require the user to take necessary
precautions. The dddrop EVO Twin may in some cases loose functionality due to ESD. This
functionality can be restored by switching the machine off and back on.
WARNING
Always switch off and unplug the machine during maintenance or adjustments.
7.2 Electrical safety
The dddrop EVO Twin operates on voltages less than 24 volt (Extra-low-voltage) internally. The
power supply used however falls in the Low Voltage directive and is CE marked.
For further information on electrical safety please refer to the data sheets of the used power supply.
WARNING
Always switch off and unplug the machine during maintenance or adjustments
7.3 Mechanical safety
The dddrop EVO Twin contains moving parts. Engine torque is however limited in order to minimize
the chance of serious injury. It is highly recommended to only reach into the printer when it is
switched off and when it is cooled down.
WARNING
Always allow the printer to cool for at least 30 minutes before any maintenance or adjustments.
7.4 Risk of burn
With nozzle temperatures up to 300 °C and heated bed temperatures up to 130 °C, the risk of burn
exists. The hot parts are covered as much as possible and have been marked with WARNING
symbols. It is highly recommended to only reach into the printer when it is switched off and when it
is cooled down.
WARNING
Only use the printer in a well ventilated area.
7.5 Health
The dddrop EVO Twin is designed to print with dddrop filaments. The use of other materials from
other manufacturers is at own risk. During print jobs fumes may find their way into the area where
the printer is set up. When printing ABS for example, small concentrations of styrene vapor may
cause headaches, fatigue, dizziness, depression, concentration problems and a feeling of
intoxication.
Proper ventilation is necessary and a long term exposure should be omitted. It is recommended to
use a fume extractor. It is obligated to make use of fume extraction in offices, classrooms etcetera.
Printing of pure PLA is considered to be safe, however ventilation is advised as fumes may also arise
from (color-) additives.
