4.3. Hardware installation and first interaction
a) Remove shipping screw
For shipping purposes, the pump inside the
device is secured with the help of a screw. This
needs to be removed before the operation of the
device. The screw is clearly shown in the image.
Remove the screw and store this for future use if
needed.
d) Attach desiccant tube
Attach the desiccant tube as shown in image.
Both clips should snap into place and click.
b) Install the bowden tube
A bowden tube can be attached to the out-
put port to facilitate the movement of the fila-
ment and avoid any entanglements. To insert a
bowden tube, connect the provided connector
by screwing it in place, then push a length of
bowden tubing securely in the connector.
c) Attach spool holder base
To install the spool holder, remove the 4 screws
as shown in the image. Place the spool holder
base and align the holes. Secure the spool hold-
er base in place with the 4 screws that you have
just removed. The cylindrical part of the spool
holder can then be screwed in place.

Drywise User Manual 9
e) Place the Drywise machine near 3D printer
• Place the Drywise machine as close to the filament extruder of your 3D
printer as possible. A shorter path ensures less filament is exposed to the
atmosphere after being properly dried. It might also mean less setup time
before printing can be started.
• Do not obstruct the air outflow from the right hand side of the device (when
looking at the Drywise from the front) as warm air needs to be expelled
from here.
• Make sure the filament paths to the Drywise machine and from the Drywise
to the printer are not obstructed so that there is no chance for the filament
to get snagged.
f) Attach the power cord to the device and plug it in a mains socket.
g) Switch on the device and follow the instructions on the touchscreen.

Drywise User Manual10
5.1. Recommendations
Ensure that the Drywise machine is placed in a suitable position and environment.
The device should be in an upright position on a solid surface. For the best
performance it should be operated at an ambient temperature of between 15 and
35oC (59 - 95oF).
Ensure that there is at least 10cm of free space to the right side of the Drywise device
for unrestricted airflow. When in use the device should be positioned out of direct
sunlight and away from liquids or humidity.
5. Operation
Always check that the filament can move freely without any obstructions from the
dryer to the printer as these can hamper the operation of the device.

Drywise User Manual 11
5.2. Material compatibility
Drywise filament dryer, is compatible with a number of materials. The list of tested
and approved materials is always growing and for an updated list kindly check our
website at drywise.co/materials
The following filaments have been tested and are Drywise approved filaments:
• Nylons
• Covestro (former DSM) Novamid ID 1030
• Covestro (former DSM) Novamid ID 1070
• BASF Ultrafuse PA
• Ultimaker Nylon
• Polymaker COPA
Never operate the device
without o-rings installed
as the device will not be
able to satisfactorily dry
your filament.
The device was intended for filament that has achieved a high level of moisture
content naturally. Filament which has been immersed in water might not perform
sufficiently well.

Specific profiles are present on the device and these should be used with the appro-
priate filament for the best performance.
DO NOT insert a different type of material other than that specific filament instructed
on the dryer and corresponding to that specific profile. Failure to observe this could
result in damage to the filament and the device.
If the filament that you want to use does not have a profile, kindly check the Drywise
website or reach out for help before trying to test with any other profile. Damage
caused to the device in this way is not covered under warranty.
Designed for 2.85mm filament only.
5.3. The drying process (normal operation)
Drying a filament and preparing it for consistent and optimal printing with your 3D
printer is easy with the Drywise dryer device:
Switch on the device us-
ing the power button.
Select the “Start
Drying” option once
the device loads to
the home screen.
A B D
C
Check that the
desiccant container
is connected
correctly on the
back of the device.
Check that no
previous filament is
inserted.
Check that the
filament input
and ourput ports
are securely fixed
in place and the
o-rings installed.
It is essential to use Drywise Pre-Heater (sold separately) to be able to dry the follow-
ing materials:
• Carbon fibre filled nylons
• Glass fibre filled nylons
• Luvocom PAHT resin based filaments
• Other specific materials as instructed by the Drywise UI.

The device will now prompt
you to prepare the filament
that you want to use by
shaping the end to a cone
point. This can be done
with any of your preferred
tools or else using the tool
provided. This is a very
important step as it en-
sures that the filament will
slide smoothly through the
device.
Select the filament that you would like to use and
click “NEXT” to continue.
For some specific materials, including all CF and
GF materials, the Drywise Pre-Heater add-on
is needed. These materials cannot be selected
unless the add-on is attached. Add-on is sold
separately
More details are available at Drywise website
https://drywise.co/add-ons.
The Pre-Heater expands the material processing
capabilities of the Drywise dryer. Carbon fibre,
glass fibre reinforced nylons and some other
specific materials e.g PAHT require this add-on to
work.
Drywise Pre-Heater add-on

Follow these guidelines to make the most out
of the light indications:
• When flashing green it is ok to pull the
filament from the out port.
• When solid green the filament
is loaded correctly needing no more
adjustments and you can move
on to the next steps.
• When flashing red the filament has been
pulled out too much. You are requested to
pull some filament back into the device.

To load the filament the interaction with the
device has to happen on the backend. To
help and guide the user with this process
the Drywise dryer machine has LEDs built in
the filament movement sensor. These light
up in different patterns to help you gauge
how much filament to push or pull. The same
lighting pattern is also replicated on the
front of the machine where the Drywise logo
lights up.
3
It is now time to insert the
filament from the input port
all the way to the output
port. Insert the filament
with the previously shaped
side first and push the
filament until the LEDs turn
solid green.
Press “CONFIRM” once you
have correctly loaded the
filament.

Drywise User Manual 15

Once the filament has been correctly loaded, the
system will check that everything is in order to en-
sure the correct filament drying.
Anytime the dryer is left idle (i.e. there is no filament movement detected during print-
ing or no human interaction after a prompt), it will go into standby mode for safety
purposes. This means that the user might need to restart the cycle.
The device will alert you if any of the components
are not functioning correctly.
Such alerts could be:
• To check if the input and output ports are sealed
correctly
• If the o-rings are fine or need replacing
• If the desiccant is connected correctly
• If the desiccant needs replacing with a regener-
ated one

It is now time to start dry-
ing the loaded filament.
Press Start and a drying
cycle will begin. This will
take about 40 minutes.
The countdown timer
shows how much time is
remaining for this dry-
ing cycle to be complete.
Once this drying cycle is
done the dryer will start
beeping to alert you.
Always wear gloves when handling filament which has just been conditioned by the
Drywise dryer. Filament coming out of the output port after a drying cycle might be
too hot to handle with bare hands.

Drywise User Manual16

When the pre-drying cycle is complete
the machine will start beeping. If you
press on the mute button the beeping
(indicator noise) will stop.
Beeping signals that the first part of the
filament is dried and ready to be loaded
into the printer. Wear the heat resistant
gloves and pull the filament as guided by
the LEDs. It is important to pull out the fil-
ament until the LED lights are solid green.
If the LEDs are flashing red, pull some
filament back into the device. (it might
actually be easier to pull the filament
from the input port instead of pushing
from the output port).
Once the filament has been pulled,
proceed with cutting the first 10 cm of the
filament and loading into the printer.
For the best results purge the filament
until dry filament starts to be extruded.
This can be observed when the filament
starts extruding out of the nozzle
smoothly and without any bubbling.
Once your printer is successfully loaded,
you can press “PRINTER LOADED” on the
dryer. This will start preparing the next
part of the filament.
page.
Caution when
handling the
conditioned filament,
as it might still be hot
to the touch.

Drywise User Manual 17

Once “PRINTER LOADED” has been
pressed, the dryer will prepare the start
of the next section of filament before
continuous drying during printing can
commence.
Without this preparation there could be
a filament section that would still remain
undried and will give suboptimal results.
Once this step is done you will be prompt-
ed by the dryer, which will start beeping.
8
Pressing the mute but-
ton will stop the beep-
ing. Please proceed with
starting the print job on
your printer and hitting
the “PRINT STARTED”
button on the dryer. This
will put the dryer in print-
ing mode.
The device will contin-
ue drying your filament,
inline, until you press
“PRINTING COMPLETED”
or if the device does not
sense any filament move-
ment for more than 20
minutes during printing.

Drywise User Manual18
If for some reason the printer stops print-
ing, the dryer will sense this and after
giving the user time to fix the issue, it will
abort the current operation if filament
movement does not resume. Drying will
also automatically stop once printing is
finished.

Drywise User Manual 19
6.1. Desiccant
If the desiccant needs regeneration the system will inform you. Refer to the “User Operations”
section in this manual for the right steps to regenerate the desiccant.
If you won’t be operating the device for a long period of time remove the desiccant container
from the device. The desiccant container has valved connectors which, once engaged (by re-
moving from the mating connector) should be able to protect the desiccant from absorbing
humidity.
Operating the device with saturated desiccant will not give satisfactory results.
6.2. Firmware
Having the latest firmware ensures that you can get the most out of your Drywise dryer ma-
chine.
To update the firmware:
• Download the firmware update file from https://drywise.co/downloads to your laptop or
computer.
• Connect your Drywise filament dryer device to the laptop or computer.
• Run the downloaded file and wait for the update procedure to finish.
• The Drywise filament dryer device should be updated with the latest firmware.
6.3. Cleaning
When carrying out any of these cleaning procedures, always switch off and unplug the ma-
chine from the mains supply.
Cleaning the fans - use a brush to gently clean the fans from the outside of the device if
these accumulate dust. Compressed air can also be used to do this.
Outer surface - use a damp cloth to clean the outer surfaces of the device.
The Drywise device has a self-test routine that checks the vital components in the machine
and reports the status of each of these components. If any component needs to be replaced
it will be highlighted here. It is suggested to run this self-test at least once a month.
For the best filament drying performance, the integrity of the closed loop is critical. Thus,
ensuring that the o-rings are in good shape is essential. The machine will sense if there is an
issue with the o-rings or any other component in the seal of the system. It will highlight this to
you via an on-screen message. Please make sure to follow through.
6. Maintenance

Drywise User Manual20
7.1. Change desiccant
This screen will pop-up when the
system senses that the desiccant
might need regeneration. You can
follow the instructions to replace
the desiccant with a previously
regenerated one and continue
with normal operation. If you do
not have a previously regenerated
desiccant kindly abort the dryer
operation and regenerate the
desiccant before trying to dry the
filament. For the correct procedures
to replace the desiccant container
and to regenerate the desiccant
kindly refer to the “User Operations”
section in this manual.
7. Warning Message Screens
7.2. Connect desiccant
This screen will pop-up if the system
senses that the seal on the system
is not sufficient. This means that
the o-rings need to be replaced or
re-seated as they are not providing
a good enough seal on the filament.
For the correct o-ring replacement
procedure refer to the “User
Operations” section in this manual.
