This topic summarizes the pre-build checklist.
See your Sinter application online Help for
details.
✓
Powder availability/flow (IPC/IRS)
✓
Nitrogen availability/flow (if no N2
generator)
✓
Air pressure/flow
✓
Coolant flow
✓
Hard drive space
Check the following items before starting a build:
✓
At least 50 MB of hard-disk space on the SLS
system computer.
✓
Enough nitrogen available (if you’re not using
the 3D Systems Nitrogen Generator).
✓
The SLS system uses as much as 2800 liters of
gaseous nitrogen during the initial purge for
a build, then up to 7 lpm during the build.
L
If you’re not using the Nitrogen Generator,
and If you know how long the build will
take, calculate the nitrogen needed; if you
are not sure, estimate and make sure you
have plenty of extra nitrogen and/or the
ability to easily switch nitrogen tanks.
Some materials require less nitrogen, and
some require no nitrogen. Consult the
Material Guide for more information.
✓
Enough powder in the IRS Blender bin.
See Verifying Sufficient Powder on page 71.
✓
Verify that the gas flow rates are set properly.

Gauge Panel on page
