Safety Instructions
Building the printer will require a certain amount of physical dexterity, common sense and a
thorough understanding of what you are doing. We have provided this detailed instruction to help
you assemble it easily.
However ultimately we cannot be responsible for your health and safety whilst building or
operating the printer, with that in mind be sure you are confident with what you are doing prior to
commencing with building or buying. Read the entire manual to enable you to make an informed
decision.
Building and operating involves electricity, so all necessary precautions should be taken and
adhered to, the printer runs on 12V supplied by a certified power supply, so you shouldn’t ever have
to get involved with anything over 12V but bear in mind there can still be high currents involved
and even at 12V they shouldn’t be taken lightly.
High temperatures are involved with 3D Printing, the Extrusion nozzle of the hot end can run about
230°C, the heated bed runs 110°C and the molten plastic extruded will initially be at around 200°C,
so special care and attention should be made when handling these parts of the printer during
operation.
Check the power input of the power supply unit. You can choose either 110V or 220V according to
the Power regulation in your country.
Tear off the yellow sticky note to check it. You can use a hard stick to reach into the power box and
switch it. (依旧保留吗)
We wouldn’t recommend leaving your printer running unattended, or at least until you are confident
to do so. We cannot be held responsible for any loss, damage, threat, hurt or other negligent result
from either building or using the printer.

2. Hotbed Leveling
Before printing, we need to do hotbed leveling. Only after this step can the quality of printed parts
get improved. Otherwise the un-leveling gap between the hotbed and extrusion head will affect the
filament adhesion to the hotbed, which would cause poor print quality or even not printing.

2.2 Coarse Tuning of distance between the nozzle and the hotbed
*If the nozzle is far from the surface of hotbed, loosen the M3x35mm screw to decrease the
distance between the nozzle and the hotbed.
*If the nozzle is too close to the surface of hotbed, tighten the M3x35mm screw to increase the
distance between the nozzle and the hotbed.
You may need to calibrate for many times at this step.
The recommended distance between the nozzle and the hotbed is 0.5-1mm.

2.3 Fine Tuning
After the initial adjustment, home the printer. Disable the stepper motors via LCD control panel,
manually move the extruder to the four corners of the hot bed and fine-tune the wing nut at each
corner to level the distances between the extrusion head and four corners. During adjustment, you
can put a piece of A4 paper (half fold it) between the nozzle and hotbed. If you can feel a bit friction
pulling the paper back and forth, the distance is proper.
After finishing the adjustment of four corners, the entire leveling process is done. You can also
move the extruder to the center of hotbed to verify leveling outcome.

3. Print Settings
EasyPrint 3D provides two print setting modes: quick mode and custom mode. The [quick] mode is
designed for entry-level users, while the [custom] mode is tailored for expert user with finer
printing parameters.
3.1 Quick mode
Choose [quick] tab. Here, we have prepared 3 printing quality settings for you.
Quality
Choose Low, Standard, or High quality to specify the surface quality of your 3D print.
•Objects sliced with the High quality profile will have finer layers and will print more
slowly.
•Objects sliced with the Standard quality profile will be printed using the default settings.
•Objects sliced using the Low quality profile will be printed with thicker layers and will
print faster.
Infill: The density of the infilling structure.

Extruder temperature: Different filament requires different temperature for extruders; please
refer to the suggested temperature.
Layer height: the thickness of each layer. You can leave it as default.
Supports
Select this checkbox to have your object printed with support structures. EasyPrint 3D will
automatically generate supports for any overhanging sections of your object. Supports will be easily
removable once you remove your finished object from the build plate.
When you have finished the setting process, click [Apply]. The current settings will be used to slice
your model next time you print or export a print file.
3.2 Custom mode
For advanced users who want to exert more sophisticated control over the whole printing
process, EasyPrint 3D provides a series of parameters for you to engineer the printing configuration.
3.2.1 Create a new configuration/setting
To customize settings, you need to create a new setting first. Click the [create new conf.] tab
and enter the name of new configuration in the textbox. Click [Ok].

3.2.2 Print settings
Choose the [custom] tab to enjoy the sophisticated print settings.
1) Accuracy：
a. Layer Height:

www.geeetech.com
ShenZhen GETECH
CO.,LTD
11
The layer height is one of the most often adjusted settings. It is the thickness of one printed
layer (in mm). With a thinner layer height you will increase the quality of the print, leading to a
smoother surface and more detail visible in the Z-direction (height) of the model. On the other hand,
by using thicker layers you can decrease the print time substantially.
b. Nozzle diameter: showing the diameter of the current nozzle.
c. Solid layers: The loops needed to finish just one layer.
d. Perimeter: The loops needed to finish printing one layer to make the printout more solid and the
surface finish smoother.
2) Skirt:
A skirt is a line printed around the object on the first layer, but not connected to the object.
This helps prime the extrusion and can also be a good check for bed leveling before the print starts
and it can ensure that the material is flowing smoothly from the extruder before it starts on the

model proper.
a. Loops: The number of skirt lines printed around the model. One loop is usually sufficient.
b. Distance from object: The distance between the object and the skirt. The default of 6mm is
usually sufficient.
c. Skirt height: The number of layers to lay down a skirt for. For ensuring the material is
flowing smoothly, one layer is sufficient, however the skirt function can also be used to build walls
around the object in case it should be protected from draughts.
3) Retraction:

www.geeetech.com
ShenZhen GETECH
CO.,LTD
13
Retraction is used at the places in a print where the printer has to do a travel move between
two printed parts. Without retraction extruded material will hang between the parts. This means that
the filament is pulled back by the feeder, so that it doesn’t leak from the nozzle during the travel
moves. By using retraction, “stringing” (thin threads of plastic in between the printed parts) is
prevented, resulting in a much cleaner final model. You have to be careful with flexible materials or
models that require a lot of retractions, as that might lead to grinding of the filament.
a. Length: The number of millimeters to retract. Note that the measurement is taken from the
raw filament entering the extruder. A value of between 1 and 2mm is usually recommended.
Bowden extruders may need up to 4 or 5mm due to the hysteresis introduced by the tube.
b. Lift Z: Raises the entire extruder on the Z axis by that many millimeters during each travel.
This can be useful to ensure the nozzle will not catch on any already laid filament; however it is
usually not necessary and will slow the print speed. A value of 0.1mm is usually sufficient.
c. Speed: The speed at which the extruder motor will pull back the filament. The value should
be set to as quick as the extruder can handle without skipping steps, and it is worth experimenting
with this value to find the quickest retraction possible.
4) Infill:

www.geeetech.com
ShenZhen GETECH
CO.,LTD
14
a. Fill Density: The infill density defines the amount of plastic used inside the print. A higher
infill density means that there is more plastic on the inside of your print, leading to a stronger object.
An infill density around 20% is used for models with a visual purpose; higher densities can be used
for end-use parts.
c. Fill angle: By default the infill pattern runs at 45° to the model to provide the best adhesion
to wall structures. Infill extrusions that run adjacent to perimeters are liable to delaminate under
stress. Some models may benefit from rotating the fill angle to ensure the optimal direction of the
extrusion.
d. Fill Pattern: It is the pattern of filling shape which effects printing duration.
EasyPrint 3D offers seven infill patterns, including four regular flavors, and three more exotic

ones. The numbers on the right of each figure are a rough estimate of material used and time taken
for a simple 20mm cube model. Note that this is only indicative, as model complexity and other
factors will affect time and material.
