Sintering
The high-temperature Programat S1 furnace is preferably used for sintering IPS e.max ZirCAD frameworks. The furnace's
programs are optimally adjusted to IPS e.max CAD and the material's shrinkage during sintering and thus allow optimum
results to be achieved.
Finishing Drying Sintering Checking
Optional
Shading
Prior to sintering, allow the IPS e.max ZirCAD frameworks to dry for a sufficient amount of time according to the size
(page 26). Please keep in mind that IPS e.max ZirCAD frameworks which are sintered while moist are damaged as a result
to the high heating rate.
For the sintering process in the Programat S1, the following points should be observed: Positioning of dried
IPS e.max ZirCAD frameworks on the sintering tray supplied with Programat S1:
– Do not use ZrO
2
sintering beads in the Programat S1.
– The sinter tray can be entirely filled with IPS e.max ZirCAD frameworks. Make sure that the frameworks do not
touch each other.
– Simultaneous sintering of single-tooth and bridge frameworks as well as frameworks with a sinter support
structure is possible.
– Observe the program selection.
– Provide even support for the IPS e.max ZirCAD frameworks.
– Bridge frameworks should not exclusively be supported by the abutment crowns. The bridge pontic must
be supported. The abutment crowns do not absolutely have to come into contact with the sinter tray.
Observe the notes in the IPS e.max ZirCAD Instructions for Use!
– Arrange the IPS e.max ZirCAD frameworks in concentric circles on the sinter tray, particularly bridge frameworks.
Important: Do not place any frameworks over the separation in the sinter tray.
– Place the loaded sinter tray in its intended position in the centre of the sintering chamber of the Programat S1 using the
sinter tray fork.
Arrange the frameworks in concentric circles on the sinter tray. This ensures even temperature
distribution within the framework during heating and cooling. Frameworks with or without sinter support structure may be sintered simultaneously.
Observe the program selection. The frameworks must not touch each other.
Do not place any frameworks over the separation in the sinter tray.
Select the sintering program in accordance with the materials used (e.g. use of IPS e.max ZirCAD Colouring Liquids) and
the indications (single-tooth or bridge framework) and start the process.
Remove the sinter tray from the Programat S1 after the sintering process using the sinter tray fork. Always allow the hot
IPS e.max ZirCAD frameworks to cool to room temperature before proceeding.
For details on the sintering process, please refer to the IPS e.max ZirCAD Instructions for Use and the Programat S1
Operating Instructions.
