Chocolate 3D printer for commercial use.
The choc mate 2 is a 3D printer for cho-
colate or couverture with a print area of
340x232x160mm.
It has a heatable print head with two tempe-
rature control circuits. The printer also has a
heated preheater for preparing another car-
tridge. In the Z direction, the minimum layer
structures and very smooth surfaces can also
be printed. In the X-Y direction, a resolution of
approx. 0.1 mm is achieved. The actual accu-
racy when printing chocolate depends largely
on the chocolate used, the temperature and
the ambient conditions.
An integrated print server with a 4.3“ touch
display makes it possible to operate the prin-
ter independently. Due to the network inter-
faces, the printer can also be operated with
the help of a browser.
We clearly point out that the system must not
be operated unattended.
Any additional devices must be matched to
the main unit (if you have any queries, please
contact the manufacturer).

user of the 3D printer has access to a copy of
this manual and has read and understood it.
The requirements or procedures for the as-
sembly, handling, storage, use or disposal of
the device are beyond our control and know-
ledge. Therefore, for this reason and others,

ant information on the proper use and safety
of the choc mate 2.
Read these instructions carefully before
using the appliance.
Observing this manual and taking the infor-
mation it contains into account and applying
it is part of the intended use.
Improper operation can lead to dangerous si-
tuations. Use of the 3D printer under conditi-
ons other than those described in this manual
here is considered improper use and leads
to the exclusion of any liability and warranty
claims.
The device may only be operated under the
constant supervision of appropriately trained
persons.

Operation of the choc mate 2 is prohibited
under the following circumstances:
• The 3D printer is not being used for its
intended purpose.
• The choc mate 2 or individual compo-
nents are damaged, the electrical equip-
ment or parts of the insulation are faulty
or incorrectly installed
• The choc mate 2 is not working properly
• Mechanical components or the control

2.2. Suitability for food
2.3. General information on safety
The chocolate printer has been developed
according to the current state of knowledge
and taking into account the currently applica-
ble regulations for use with food (in particular
chocolate).

ded by our suppliers, that the following com-
ponents comply with the guidelines of Re-
gulation (EC) No. 10/2011 and are therefore
suitable for contact with food:
• Piston (POM)
• Sealing rings (Silicone)
• Cartridges (PP)
• Nozzles (PP and stainless steel)
• Foils (PP)
• Wire (stainless steel)
The choc mate 2 generates heat during ope-
ration and has moving parts that can cause
injury. Never reach into the 3D printer while it
is in operation. The heating elements in parti-
cular can reach high temperatures. Wait un-
touching them. Only operate the choc mate
2 using the touch display on the front or the
not make any changes or adjustments to the
choc mate 2 that are not approved by the
manufacturer. Do not store any objects in or
on the choc mate 2. The choc mate 2 is not in-
tended for use by persons (including children)
with reduced physical and/or mental capa-
bilities, or lack of experience and knowledge,
unless they have been given supervision or
instruction concerning use of the appliance
by a person responsible for their safety. Chil-
dren should never be allowed to use the choc
mate 2 unsupervised. When opening the prin-
sure that the mains plug is disconnected from
the socket.

2.4. Electrical safety
2.5. Mechanical safety
The choc mate 2 is operated with 24V (DC)
and 230V (AC). Touching live components
can be life-threatening and cause the most
serious injuries.
The power supply complies with all CE mar-
king regulations and is protected against
short circuit, overload, overvoltage and
overheating. For further information regar-
ding electrical safety, please refer to Mean-
Well‘s EU Declaration of Conformity for the
GST60A24-P1J desktop power supply.
Only use the choc mate 2 with the mains ca-
ble and mains adapter supplied by the ma-
nufacturer.
Make sure that the mains cable (power supply
cable) is not damaged. Devices with a dama-
ged mains cable must be disconnected from
the mains (pull out the mains plug) and re-
paired by a specialist electrician before being
used again.
Only connect the 3D printer according to the
Work on the electrical equipment of the choc
mate 2 and the power supply may only be
Always disconnect the 3D printer from the po-
wer supply by pulling the power cable before
carrying out cleaning, maintenance or repair
work.
Check the condition of cables and insulation
regularly and replace damaged parts imme-
diately.
Installation and operation of the 3D printer in
damp rooms or outdoors is not permitted.
The choc mate 2 contains numerous moving
parts. However, the stepper motors of the in-
dividual axes do not have enough power to
cause serious injuries. In addition, the moving
drive parts are covered with a protective co-
ver. Nevertheless, you should only reach into
-
ting clothing. Loose clothing such as scarves,
jewellery and chains pose a risk of injury.
Attention: Observe the overrun of the printer.

The print head including nozzle and the pre-
heater are heated. Temperatures up to 45°C
can be set. Although these temperatures are
not dangerous, the heating elements them-

safe touching.
Caution:
The heating elements still have an increased
temperature! Wear protective clothing!
The choc mate 2 has been developed and bu-
ilt according to applicable standards and ca-
refully tested for functionality before delivery,
so that it is safe and ready for operation upon
delivery. Nevertheless, dangerous situations
or damage to property may occur as a re-
sult of the production process itself, incorrect
operation or technical defects.
The risk of dangerous situations is increased
by:
• Use of the choc mate 2 other than as in-
tended.
• Improper operation of the 3D printer.
• Operating the 3D printer in an unsafe or
unsuitable condition.
•
and excessive soiling.
Therefore:
• Only use the 3D printer as intended.
• The choc mate 2 must always be in per-
fect and safe condition.
• Check the 3D printer for wear, damage
and cleanliness before each use and at
regular intervals.
• Make sure that no one can be injured by
the 3D printer.
• Immediately rectify any fault or visible
damage.
•
not possible, take the 3D printer out of
service and do not use it again until all
• Observe local accident prevention regu-
lations.
• Ensure that every user of the 3D printer
has received instruction for this device
and has access to this user manual at all
times.
• Use materials other than chocolate at
your own risk.

2.8. Cleaning
2.9. Mains voltage
2.10. Risk of injury
Unplug the appliance from the mains befo-
re cleaning. Use a dry cloth for cleaning and
clean only the surface.
The chemicals required for maintenance and
care must be handled properly and in com-
pliance with the applicable regulations and
instructions for use of the chemicals. The ma-
nufacturer‘s instructions must be followed,
appropriate protective clothing must be worn
and the dosage instructions must be strictly
adhered to. Improper handling of chemicals
can cause damage to property and personal
injury for which the operator alone is liable.
Operate the unit only at the mains voltage
of the unit or on the external power supply
unit). The unit may only be connected to the
mains and switched on after all connections
have been checked.
Some hazards are function-related and the-
refore cannot be avoided by design. In order
to avoid injuries, it is necessary that the user
is aware of these hazards and is correspon-
dingly attentive during operation. The opera-
tor is responsible for observing appropriate
protective measures.
The preceding safety instructions are inten-
ded to protect the operator choc mate 2. It is
the operator‘s duty to ensure that everyone
who works with or on the 3D printer is familiar
with this chapter and observes the informa-
tion contained therein.
