• Oxygen tab
This tab indicates the settings related to the oxygen value:
• General safety O2 threshold : this setting
value is an absolute percentage of oxygen. The
manufacturing will stop immediately if the oxygen
value is upper than this setting. If the setting is
null, this function is disabled.
• Minimum O2 threshold to launch a
manufacturing : it defines the minimum value
of oxygen to produce. If oxygen value is upper
the setting, starting a job is not permitted for
Operator level and is permitted for other levels (a warning message will be displayed in such case).
• Manufacturing stop threshold : this setting value is a percentage relative to the oxygen set point. The
manufacturing will stop at the end of the layer if the oxygen value is upper than this setting. If the setting is null,
this function is disabled.
The values are read-only . Editing these values requires higher access privilege (see "User level selection"
on page 47) .
• Preparation tab
This tab shows the default settings related to the layering sequence during the preparation cycle (see section "Creating the
powder bed" on page 61):
• Sequence : name of the layering sequence used.
• Layer thickness : thickness of the layers (in µm).
• Compacting rate : percentage of the layer
thickness added to the layer thickness.
• Compacting iteration : no longer used.
• Powder raising : value of the feeding piston rising
for each layer (in µm).
• Powder raising iteration : number of iterations of
the loop in the layering sequence.
• Initial descent : value of the first movement
(relative position) of the sintering piston.
Determine the positions values of the sintering
piston for the iteration scraping (in µm).
The values are read-only . Editing these values requires higher access privilege (see "User level selection"
on page 47) .
