Dremel 3D20 is intended to operate in

temperature between 16-29° C (60 - 85° F).

Do not move or bump Dremel 3D20 or the
extruder during operation. The object may

build incorrectly.

Do not change filament spool unless the
building process is completed, stopped,
or paused. Changing the filament during

building will cancel the object and may
damage the extruder.

Do not pull the filament out of the
extruder. Pulling filament out of the top of the

extruder can result in clogs. Follow on-screen
instructions to properly load filament.

Use extra care not to damage the extruder
tip when clearing debris. Dremel 3D20 will

not work properly with damaged extruder tip
and will require replacement.

(140°F). Contact with the extruder tip during
or after operation before tip has cooled may
result in personal injury.

CAUTION: Before every build make sure that
the build platform is covered with Dremel
specified build tape. Use of improper build
tape may result in equipment damage and
poor object build quality.

LEVELING BUILD PLATFORM

It is important you level the build platform
every time you replace the build tape or
reinstall the build platform to ensure that the
build platform is evenly spaced from the
extruder head. Make sure to remove any air
bubbles from between the build platform and
the build tape. Not leveling the build platform
or eliminating air bubbles may cause objects
to not build properly.

Wait for the extruder head to cool to at least
60C (140F) before leveling build platform.
Extruder temperature can be monitored on
the touch screen (See Preheat section on
page 19).

1. Make sure you have placed build tape
over the build platform. Applying build tape
to the build platform after leveling may
effect the consistency of your object.

Best Practices

1. ALWAYS USE BUILD TAPE.

2. Ensure your build platform is level before

every object.

3. Ensure spool is installed properly and

can rotate freely.

4. When using your Dremel 3D20 for the

first time or after changing filament, allow
Dremel 3D20 to extrude until material is
consistent with the installed filament
color.

5. It is important to watch your Dremel 3D20

begin building objects. Your object is
most likely to experience difficulty in the
beginning. Thankfully, this is also the
most convenient time to cancel the
object, clean the build platform, and start
your object again. Remain near the
Dremel 3D20 during the building process.

6. It is important to save your Dremel 3D20

packaging as it will make re-boxing and
transporting your Dremel 3D20 easier.

7. Ensure that you store filament spools in

an environment that is not moist or too
hot. It is recommended that you do not
remove the filament spool from its airtight
packaging until use.

8. Use object removal tool gently to avoid

damaging the build platform or object.

9. Whenever possible, it is best to locate
your object in the center of the build
platform. Using the best orientation for
your object is critical. Ensure that your
object is located on the build platform
and that you are using the best
orientation for building.

10. For steep overhangs (Less than 45
degree angle) it is recommended to build
with support.

11. To prevent build tape from peeling during
the build, wrap the build tape underneath
the build platform.

12. Always remove the build platform before
removing the object.

13. Use the home feature before loading a
filament spool. Also, it is recommended
to remove the build platform before
loading a filament spool.

14. Low speed sanding is recommended to
prevent remelting of the object.

15. The Dremel 3D software will display the
weight of each model. You can determine
whether you have enough filament to
complete your object before building by
weighing the filament and spool then
subtracting the weight of the spool.
