Once blending is complete, the IRS resumes
processing other transfer requests for loading
Virgin or Used Powders into their respective bins
or supplying blended powder to the LS machines
connected to the IRS.
WHEN POWDER SUPPLY IS LOW - BLENDING A
PARTIAL BATCH
If the IRS does not have enough powder (virgin or
used) to blend a full batch with the specified
percent virgin, it will blend a “less-than-full”
partial batch with the same percent virgin as a
full batch. The IRS does this by blending all the
limiting amount of powder with a proportionally
smaller amount of the other powder.
Example: If the percent virgin is 60% —3 kg virgin
to 2 kg used—and the used bin only has 1 kg left,
the IRS will blend a partial batch using the entire
1 kg of used, but only 1.5 kg of virgin. This makes
the partial batch blend ratio 1.5.
When the IRS blends a partial batch, it flashes the
yellow stacklight and
Please Load Used Powder
or Change Percent Virgin appears on the operator
panel display.

The percent virgin determines the blend ratio .
The percent used is derived from the percent
virgin.
When the Blender runs out of powder, the IRS
shuts down, its red stacklight illuminates, and
Blender Empty appears on the operator panel
display.
