Drying
In order to prevent damaging the IPS e.max ZirCAD framework during sintering, the IPS e.max ZirCAD framework must be
completely dried. Moist IPS e.max ZirCAD frameworks must not be sintered.
Please observe the following notes for drying:
– The IPS e.max ZirCAD framework must be free of dust and grinding residue.
– The framework can be dried either in a drying cabinet or under an infrared lamp.
Place the IPS e.max ZirCAD framework on the occlusal surface for drying.
– Note: If infrared lamps (250 W) are used, the distance (5-20 cm) to the object decisively influences the
temperature that develops.
– The drying time depends on the temperature. For drying the frameworks, a temperature of
140 °C (284 °F) must not be exceeded. With lower temperatures, the drying times are prolonged.
– The drying time also varies with the size of the IPS e.max ZirCAD framework. The following table
contains the required drying times.
Shading (optional)
For shading the IPS e.max ZirCAD MO 0 frameworks, four Colouring Liquids (CL1-CL4) are available*. With the shading,
the framework shade is adjusted to the IPS e.max shade concept. The allocation to the desired tooth shade is listed in the
combination table (page 50).
Note: For the detailed procedure regarding shading with IPS e.max ZirCAD Colouring Liquids, please refer to the
IPS e.max ZirCAD Instructions for Use.

Note on the use of IPS e.max ZirCAD Colouring Liquids
The frameworks shaded with IPS e.max ZirCAD Colouring Liquids must be sufficiently pre-dried in a pre-drying furnace! Air
drying is not sufficient and might result in the formation of cracks in the framework during the sintering process in the
Programat S1.
