homing Moving the part piston or roller to its
home limit to reestablish the SLS® system ’s
ability to track the device’s position. You must
home the
part piston or roller before you can
command the SLS® system to move either
device. The part piston and roller must be re-
homed (a) if the RCM is unloaded for any
reason, and (b), if the dspif process is closed.
(Exiting the Sinter application does not close
the dspif process.)
I
import ( build packet
archive ) Extracting a
build packet ( .bpf ) file,
its associated files, and
any attached notes, from a
build packet
archive ( .bpz ) file. To import a build packet
archive, open a .bpz file, either through Build
Setup ’s File > Open command or the Build
Packet Browser .
inert Atmospheric state
inside the process
chamber during a build
characterized by low oxygen and high
nitrogen concentrations. The
SLS® system
keeps the atmosphere in the process
chamber inert (5.5% oxygen or less,
depending on the material) to prevent
powder oxidation and combustion.
inerting Lowering the oxygen level and raising
the nitrogen level in the process chamber .
Inerting occurs in the Warmup stage of a
build . Before the build can advance to the
Build stage , the process chamber must be
inert . While inerting, the SLS® system delivers
maximum nitrogen flow (“purge flow”) to the
process chamber until the oxygen
concentration inside reaches the inert
setpoint.
interlock A device that makes or breaks a circuit,
depending on the condition it should satisfy.
In the
SLS® system , interlocks serve as safety
devices. Unless interlocks are in place, certain
operations cannot run.
infrared sensor
See IR sensor .
IPC I ntelligent P owder C artridge. A factory-
refillable powder container that supplies up
to 100 kg of
virgin powder to the IRS . The IPC
is a sealed canvas bag fastened to rugged
plastic pallet. The pallet has three nozzles for
connecting the powder and compressed air
lines in the
IRS umbilical . When the IRS ’s
Virgin bin gets low, the IRS draws virgin
powder from the slightly pressurized IPC
through the IRS umbilical .
