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

(see Application Guide cara Print 4.0: kulzer.com/cara-print-application)

For a detailed description of the cleaning process for objects directly attached to the build table or

objects printed on support structures, please refer to the following pages.

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

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:
