Description of the standard cleaning process.
After printing, the building platform is taken out of the printer
without removing the printed parts. Parts remain on the platform
for cleaning if not stated otherwise.
1. Pre-clean blowing: blow off residual monomer with compressed air
2. Pre-rinsing: Pre-cleaning by rinsing with isopropanol
3. First cleaning cycle: with cara Print Clean (3 min.) in isopropanol
4. Mid-process blowing: blow off with compressed air
5. Second cleaning cycle: with cara Print Clean (2 min.)
in fresh isopropanol
6. Dry cleaned parts with compressed air to remove residual isopropanol
7. Remove the dry objects from platform
Post-curing with HiLite Power 3D

3. Cleaning with cara Print Clean
We generally recommend using two cara Print Clean
devices. One is dedicated to pre-cleaning and the second
to post-cleaning with fresh isopropanol.
Attach the building platform (with printed objects still
attached) to the cara Print Clean hanger.
If any parts become detached from the building platform
during the cleaning process, they can be placed on the
part tray at the bottom of the container. Hang the building
platform, with hanger and lid, inside the container, being
careful not to damage the printed objects and ensuring the
lid of the container is shut tight.

4. Cleaning process for dima Print Stone (model material)
4.1. Manual pre-cleaning
After your objects are successfully printed, remove
the building platform from the printer and let any extra
material drain off onto a paper towel or similar.
Carefully remove any extra monomer using compressed
air. This optimizes the cleaning process and reduces the
amount of isopropanol that you will need.
Next, carefully rinse the printed object and the building
platform with isopropanol using a squirt bottle.
SAFETY WARNING:
ALWAYS USE PROTECTIVE NITRILE GLOVES, PROTECTIVE EYEWEAR AND APPROPRIATE PROTECTIVE
CLOTHING WHEN WORKING WITH MONOMERIC LIQUIDS AND ISOPROPANOL. DO NOT INHALE THE
VAPORS AND AVOID SKIN CONTACT.

After the first cleaning cycle, remove the entire assembly from cara Print Clean and remove
the building platform from the hanger.
For the first cleaning cycle, set the
time to three minutes, set the speed
to “Fast”, and start it by pressing
the start button:
The pre-cleaned model (and any dies) should be blown
dry with compressed air and then carefully removed from
the platform using the plastic spatula provided in the
accessories kit. If any additional resin flows out or can be
seen on the printed model, please remove this excess
resin using compressed air.
Place the pre-cleaned objects (model and dies) onto the part tray in the container,
making sure that the teeth point up, i.e. the model base with holes faces down.
We recommend using extra-long forceps.
4.2. Cleaning process
8
Due to the form of printed models, which generally contain hollow spaces, it is necessary
to flip the model 180° with forceps to allow any trapped air to escape. As soon as the
raising liquid level has covered the model completely, flip the model so that the teeth face
down. Let the air evapurate a few seconds and then flip the model back over to its
original position. Let then cleaning clycle run normally until the pre-set time ends the
process automatically.
2 min
This second cleaning cycle is only
two minutes long.
Set the speed to “Fast”, and start
it by pressing the start button:
After the second cleaning cycle, remove the printed objects one at a time and dry them
with compressed air.
Now you can post-cure the objects as usual.

5. Cleaning process for dima Print Gingiva Mask
Here, the cleaning process is similar to the process for models (see chapter 4). The only difference is that the printed
object does not need to be flipped during the second cleaning cycle.
1. Remove residual monomer liquid with compressed air:
3. First cleaning step for 3 min with objects attached
to build table and blow dry:
5. Printed objects during second cleaning step:
2. Rinsing with isopropanol:
4. Second cleaning step for 2min with objects removed
from build table and placed on part tray:

6. Cleaning process for all other dima Print materials
1. Remove the building platform from cara Print 4.0
2. Attach the building platform to the hanger
(choose the small or extended hanger according to the size of objects!)
3. Carefully blow with compressed air
4. Pre-rinse with isopropanol
5. Cleaning cycle 1 (3min.)
6. Carefully blow with compressed air, leave on building platform and
move to second cara Print Clean with fresh isopropanol
7. Cleaning cycle 2 (2 min.)
8. Blow dry
9. Remove objects from building platform and proceed with the recommended post-curing
