How it Works:
The 3Doodler Flow melts plastic filament and uses a motor and gears to push it through the
pen’s nozzle in a thin line. This process is called extruding or extrusion, and we will refer to it
throughout this user manual. Once extruded, the filament cools and hardens quickly, allowing
you to draw on surfaces and in the air. This user manual will show you how!
We created this User
Manual as a step-by-
step guide to get you
comfortable with your
3Doodler Flow and its
features. Once you are
familiar with these steps,
you will be able to Doodle
with confidence.

Plastic won’t stick
to the paper, or is
curling up around
the nozzle
Stop extruding and start again using the following
instructions:
Push the nozzle down onto the paper, and then resume
extruding plastic.
Drag the tip of the pen along the paper or surface in a
continuous unbroken line as if you were writing with a
pencil.
Keep your movement slow and steady. The plastic should
hold to the paper and not curl up around the nozzle.
3.
Plastic is not
extruding from my
3Doodler Flow
The plastic is not engaging properly with the drive gear:
With the pen extruding, gently push on the filament spool until
you feel it being pulled through the drive gear on its own.
If the above does not work, reverse the plastic from the pen. (See
Section 4) Snip the ends, flat, avoiding any angles, set the pen to
extrude, reinsert the filament, and try again. If the plastic is too
short to be reversed from the back of the pen, move to 3B.

The nozzle may loosen with continued usage (or in
transit). While the pen is hot (BLUE or GREEN LED
Light is on), gently turn the nozzle clockwise to tighten
it using the included tool. Stop tightening once you first
feel resistance so as to avoid over-tightening the nozzle
and breaking it.

NOTE:
If you have a spare power adapter please use it to test
your 3Doodler Flow. You will need a DC 5V2A power
supply with a USB-C port. This will help determine if
the problem is with your 3D pen or with the included
power adapter. Please make sure the power adapter is
20 watts or lower. This pen will not run on USB-C smart
power adapters.
Is the USB-C cord connected
into the power adapter?

I reversed the
plastic but can’t
get it out
It is possible that the plastic is either too short to reverse
all the way out of your pen, or that the plastic has moved
past the pen’s drive gear system.
You can check for these issues by looking through the
maintenance cover.
For both of these issues, you can try the
following options:
7A.While the pen is ON and extruding, insert a
new spool of plastic or use the included tool
to push the remaining plastic through the
nozzle tip.
Plastic reversed, but is too short to take out and is no longer
in contact with the drive gear.
Plastic is beyond drive gear.
7B.While using the
reverse feature,
remove the nozzle
and use the
unblocking tool to
push the plastic out
the back of the pen.
(See Section 3,
Step 3B)
It takes around 60-90 seconds for your pen to heat up. If, after that time,
the pen still does not heat up and the LED light remains RED, turn the
Pen OFF and back ON and try again. If that still does not work, please
contact us at [e-mail] and we will assist further.
Check your power source. This pen won’t work with smart adapters.
(Adapters that can handle multiple wattages) including USB-C ports
on computers.

SECTION 4: TIPS AND BEST PRACTICESSECTION 4: TIPS AND BEST PRACTICES
Pay attention
to filament types
and settings
• For optimal Doodling, we suggest using the correct temperature settings for
your plastic.
• Double check which type of plastic you are using before you set your pen to
the correct temperature setting (PLA or ABS). If your plastic spools get mixed
up, here is a handy table for sorting and identifying what you’re working with.
• For more detailed information on filament types, visit our FAQ:
learn.the3Doodler.com/faqs/.
PLA:
Temp: PLA Temp
LED Light: GREEN
Feature: Glossy plastic sticks to fabric,
windows, metal and other hard surfaces.
How to tell: Very rigid, no white semi-
circle ends.
ABS:
Temp: ABS Temp
LED Light: BLUE
Feature: Extruded plastic has a matte
finish. Great for drawing in the air.
How to tell: Plastic has white semi-
circle ends.

EN11/2023
Switching
between
filament types
• If you’re going from ABS to PLA, after clearing as much of the ABS as you can,
insert a spool of PLA and begin extruding while still on the ABS setting. As
soon as you see your new material extruding out, set the temperature to the
proper PLA setting.
Do not forget
to snip your
Plastic ends
• After removing a spool of plastic from the 3Doodler
Flow, cut and discard any partially melted material at the
end of the spool. This will reduce blockages or clogging
issues. Make sure your cut is flat and not angled to
reduce plastic from overlapping in the feed tube.

SECTION 4: TIPS & BEST PRACTICESSECTION 4: TIPS & BEST PRACTICES
Reverse and
remove plastic
correctly
• DO NOT pull plastic from the back of the 3Doodler Flow
other than as directed.
13
Once Plastic stops reversing,
it is safe to remove it from the
pen by gently pulling on the
back of the spool.
Make sure the pen is heated
up and ready to extrude. Double click either speed button. The back LED light
will flash to signal plastic is
reversing.
• If you ever remove your nozzle, ONLY remove the
nozzle when your pen is heated and a GREEN/BLUE
light is showing. DO NOT remove it when your 3Doodler
Flow is cold.
• If you ever need to tighten your Nozzle, DO NOT force
the Nozzle or overtighten it, as you could break the
Nozzle and permanently damage your 3Doodler Flow.
