3. Safety
a. Intended use
Only parts printed with Zetamix by Nanoe® filaments can be heat treated in Zetasinter. Reference
names of Zetasinter by Nanoe® filaments are:
- Zetamix White Zirconia®
- Zetamix Black Zirconia®
- Zetamix Alumine®
Installation must be done according the Zetasinter chamber furnace facility guide.
Installation, use and maintenance must be done according to this operation manual.
b. Assembling
Assembling must be done according to this operation manual.
Danger due to electrical Current.
During installation and maintenance
work, the electric supply to the furnace
must be switched off.
Work on electrical equipments may only
be performed by qualified personnel.
The set-up instructions and safety
regulations must be observed,
otherwise the furnace will be deemed
to have been used incorrectly,
effectively cancelling any claims
against Nanoe.

ZetaMix System®
c. Operation
Temperature controller
For each material reference, the heat program must be defined by the operator according to
guidelines provided by Nanoe (www.zetamix.fr).
The maximum safety temperature is set at 1600°C. Above, the temperature controller automatically
stops the heat treatment.
The recommended maximum working temperature is 1550°C.
Heating and cooling rates may not exceed 5oC/min (except emergency stop).
Do not turn off the power supply of the equipment if the furnace temperature is above 500°C.
After replacing the temperature controller, its settings must be adjusted before use.
Security warning
Do not touch the inner or outer surface of the furnace during or immediately after use.
Do not place any objects on the furnace body.
d. Maintenance
The power supply must be switched off before any maintenance work.
Danger due to electrical current.
During installation and maintenance
work, the electric supply to the furnace
must be switched off.
Work on the electrical equipment may
only be performed by qualified
personnel.
Hot surfaces, danger of burning.
You may not always realize that surfaces,
such as the furnace walls are hot. Do not
touch the surface.

4. Assembling
-Install the furnace according to the zetasinter chamber furnace facility guide.
-Remove the plastic cover from the heating elements under the top cover (remove the screws
to do this).
-Install the alumina tube. Put the refractory blocks on both sides of the tube (cf. Alumina tube
chapter).
-Close the circuit breaker, turn on the power →the green light comes on and the cooling fan
starts to work.
-Turn the “lock”button clockwise →the temperature control unit is now switched on.
-Press the “Turn On”button (green light is now on).

-For the first heating, the furnace chamber must be “baked”for 2 hours at 300℃. Using the
temperature controller, program and run the "baking" cycle (cf. Temperature controller
chapter):
(C01=50; t01=85; C02=300; t02=120; C03=300; t03=65; C04=100; t04=-121)
-For the first high temperature heating (above 400°C), heating element must be “passivated”
for 2 hours at 1200°C (cf. heating element chapter). Using the temperature controller,
program and run the "passivation" cycle:
(C01=50 ; t01=385 ; C02=1200; t02=120; C03=1200; t03=365; C04=100; t04=-121)
-Install the vacuum pump and the flowmeter (cf. Vacuum pump & flowmeter chapter).
-Install the bubbler (cf. Bubbler chapter).

6. MoSi2 Heating elements
In order to form a protective layer against oxidation, new heating elements must be heated to
1200°C for 2 hours with a ramp of 3°C/min (cf 4. Assembling). This process should be done when using
a Zetasinter for the first time or after replacing the heating elements.
The resistance of MoSi2 heating elements increases with use and the performance of the furnace
may decrease. Used MoSi2 heating elements are very brittle, especially after heat treatment at
1200°C.
New and used MoSi2 heating elements can be used together.
Replacement
The power must be turned off before maintenance or inspection.
①Unscrew the top cover and remove it.
②Unscrew of the clip of the connection bridge (for each rods of the U type heating element) and
remove it.
③Take off the connection bridges.

④Unscrew the clip from the ceramic jaws that hold the heating element.
⑤Remove the ceramic jaws and the refractory block.
⑥Remove the heating element which needs to be replaces
⑦Replace it with a new heating element. Replace the refractory block and ceramic jaws, make
sure they all fit in the same position as before.
4) 5) 6) 7)
⑧When tightening the clip screw, make sure that the bottom of the heating element does not touch
the bottom of the furnace chamber.
⑨Then follow the procedure④③②①to tighten the screw and complete the heating element
replacement.

9. Quick start procedure
HEATING CURVE SETTING
1. Turn on the temperature controller by turning the LOCK button.
2. The temperature controller is initializing and then displays the initial screen.
3. Press the LETF ARROW button to display the heating curve setting.
4. The screen is now displaying the first segment (C 01) and the associated temperature. This
temperature can be modified by pressing the UP or DOWN ARROWS. After pressing the UP or
DOWN ARROWS for a few second, the decimal point will be displaced to the left in order to
change the temperature faster. With the side arrows, you can choose to change the number
of units, tens, hundreds...
5. Once the first temperature is set, press the CYCLE button to move to the first segment time
setting (T 01). You can change the time displayed in minutes by pressing the UP or DOWN
ARROWS. With the side arrow, you can choose to change the number of units, tens,
hundreds...
6. Then you can cycle through the segment by pressing the CYCLE button to build the desired
heating curve. The number displayed by the letter C or T corresponds to the number of the
segment.
7. Note that a plateau can be added by choosing the same temperature as the temperature of
the previous segment. If so, the time setting of that segment corresponds to the time of the
plateau.
8. Finally, when all segments are built, you must add a final step by choosing -121 as the
temperature of the last segment and not assigning any time control to this step.
9. In order to exit the heating curve setting, you can wait 20s and the temperature controller will
automatically return to the initial screen. You can check your heating curve by entering the
heating curve setting again (back to point 3).
RUN A HEATING CURVE
1. To run the selected heating curve, you must first press the TURN ON button to close the circuit
breaker. The green button will light up.
2. Press the DOWN ARROW (run) for more than one second to start the heating curve.
3. You can hold the heating curve by pressing the DOWN ARROW for a little longer than one
second. To resume the heating curve, press the DOWN ARROW again for more than one
second. You can stop the heating curve by pressing the UP ARROW for more than one
second.
