Part 2 Melting Chocolate
The process of melting chocolate is critical to the entire process of chocolate printing
as it affects the quality of the printed result.
2.1. Melting Process
Specifications of suggested Melting Pot equipment:
Rated Voltage: Both low and high voltage units available / Weight: 3kg / Chocolate Capacity: 2.5kg
Recommended chocolate: CALLEBAUT 811NV : Recommended for the UK, Europe, USA, etc
CALLEBAUT 2815NV : Recommended for Asia Pacific (See image below)
2.1.1 Prepare the melting pot, chocolate callets, and stirrer.
Note: The amount of chocolate callets required will depend on the situation, but approximately
one fifth of a pot of chocolate callets should be adequate. Be sure to cover the pot with the
lid to maintain the temperature. In an exhibition situation the chocolate beans may need to
be melted quickly due to time restraints. (This can be done by raising the temperature up to
70°C for a short period of time and then lowering the temperature down to 32°C.)

2.1.2 Switch on the Melting Pot appliance and set the temperature between 45-50°C. Pour the
chocolate callets into the pot. (See Figure 2.1.2 below)
2.1.3 Heat the chocolate for a few minutes while stirring intermittently, and lower the
temperature to 32°C when all the chocolate callets have melted. Immediately after lowering
the temperature, add a small amount of fresh chocolate callets and stir the mixture well in
order to ensure the chocolate is evenly heated. The chocolate is ready to use when it is
completely smooth. (See Figure 2.1.3 below)
2.1.4 Attach the green nozzle from the provided tool box onto the end of the syringe, making sure
that the syringe piston is all the way down and there is no air inside the syringe. Start slowly
loading the melted chocolate into the syringe at a slow and steady pace. Try not to let any
air get into the syringe. (See Figure 2.1.4 below)
Note: Try not to let any air get into the syringe when loading as this will affect the printing quality.
During the loading process, a squeaking noiseindicates that air is getting into the syringe, so the
piston should be gently pushed down until a small amount of chocolate is purged to help remove
the air. After successfully removing any air, loading can continue. Hold the syringe facing
downwards after the loading process and gently push the piston until chocolate starts coming out
–This is to make sure there is no air in the tip of the syringe. Wipe off any excess chocolate.

2.1.5 Exchange the green nozzle with a metal nozzle and prepare to install the syringe in the
printer. (See Figure 2.1.5 below) (See Figure 2.1.5.2 below for syringe details)
Important: You should regularly examine your nozzles. If you should damage your nozzles (or you are
unsure of their strength, shape and integrity) do not use them –Replace them.

2.2 Please Note
2.2.1 The amount of chocolate put into the pot during the first step of the melting process
determines how long the process will take. If you want to speed up the melting process use
less chocolate and increase the temperature while stirring frequently. After adding fresh
callets to the melted chocolate, stir continuously. By following the steps above the melting
process will be relatively shortened.
2.2.2 Before loading a syringe, the chocolate needs to have completely melted with no granules
visible when stirring –any remaining granules can cause a blockage during printing.
2.2.3 In order to increase the loading efficiency and achieve the best printing quality, it is not
recommended to continuously reuse the same chocolate.
2.2.4 It is recommended that the syringe be cleaned immediately after use by using the provided
brush in the tool box. This is to prevent the rubber bung getting stuck in the syringe.
2.2.5 In order to ensure the best printing results, it is recommended to use the same or similar
chocolate (see picture above) that Choc Edge uses for printing, noting that printing results
can be affected by the varying melting temperatures of different types and brands of
chocolate.

(See Figure 3.2.11.2 below)
Enter the value of 40 into the numerical window.
Note: For Option 2, a value of no more than 40 can be entered at this time.
This is to prevent novice users from lowering the nozzle too close to the
printing platform. Fine tuning to (e.g.) 42 can still be done after the Z-axis
has moved down into the position of 40.

3.2.12 On the next screen, press the ↑ or ↓keys until the gap between nozzle and printing
platform is approximately 2mm, which is a suitable starting height when using a 0.8mm
nozzle. If 2mm appears to be too high for your design, try 1.5mm. [ Hint: A food-safe metallic
disc from the tool box can be used as a height guide - The disc is 0.5mm thick, so your nozzle should
be positioned approximately 1.5mm above this disc. If your nozzle touches the disc or is close to it,
your nozzle is too low; Raise the nozzle up by 1mm or more. ]
Once the desired height is set, press Save.
3.2.13 After setting the height, the screen will jump back to the home page automatically.

3.3 Note
3.3.1 Before using your Choc Creator for the first time, please check the printing platform is level
to make sure it has not been affected by shipping of the machine. If the platform appears to
need adjustment, refer to the video on the provided USB flash drive.
3.3.2 Clean the syringe after every use in order to avoid the rubber bung sticking inside the
syringe. If it does stick, put the entire syringe into a bowl of hot water (°C) for a few minutes
and pull the rubber bung out with a pair of tweezers. When the rubber bung wears out, it
can be replaced with the spare that is provided in the tool box.
3.3.3 Eletiit euieet: The opeatig oltage of the Cho Ceatos poe adapte is
between 100-240V. An unstable voltage or exceeding the range of the operating voltage can
damage the power adapter. A damaged power adapter will not light up when plugged in.
3.3.4 Before printing, put a piece of paper on the platform and fasten it in place using the four
magnets from the tool box. Displacement of the paper will affect the quality of printing.
Additionally, try to avoid placing the magnets close to the metallic nozzle. Placing the four
magnets on all four corners of the paper is the best option.
3.3.5 When printing for the first time, test the machine by printing a square. A Test Square file is
included as one of the pre-loaded design files. (see Figure 3.3.5 below)

3.3.10 If anything unusual occurs during printing, press the emergency stop button and the
machine will stop instantly. Releasing the button does not make the machine continue
printing from where it stopped. After pressing the emergency stop button, the machine will
need to be powered off and restarted. The printer will not work until the emergency stop
button has been released. (See Figure 3.3.10 below)
