IPM I mage P rojection M odule. Contains the
laser , laser focusing and scanning optics, and
removable laser window . The IPM is mounted
on top of the SLS® system , above the process
chamber .
IR calibration Iteratively measuring of the
blackbody (reference) temperature with the
IR sensor , then adjusting the IR sensor output
to match the reference temperature. IR
calibration can be done automatically every
n
layers during a build , or manually using the
IR CAL button in Man Ops . If you change the
type of material in the SLS® system , you must
perform a manual (“offline”) IR calibration
using the
IR CAL button in Man Ops before
starting your first build with the new
material.
IR sensor A noncontact part bed temperature
measuring device mounted on a hinged
panel beside the
blackbody on the right wall
of the process chamber . The IR sensor detects
the emissivity of infrared energy at the part
bed and maps it to part bed temperature
based on the most recent IR sensor
calibration.
IRS I ntegrated R ecycling S tation. Mixes new
virgin powder from the IPC with used powder
(from a part cake) and transports it to the
SLS® system feed hopper on demand.
IRS umbilical Flexible 5-meter harness of
powder tubing, compressed air lines, and
electrical cables from the
IRS that connects to
the IPC when the IRS unloads virgin powder
from the IPC .
IRS Ready mode IRS “run”
state in which powder
transfers occur. In IRS
Ready mode, the
IRS
can unload an IPC , blend powder, send
powder to SLS® system (s), and receive
powder from a BOS .
IRS Standby mode IRS
“idle” state in which no
powder transfers occur.
IRS Standby mode is
mainly for
IRS setup, diagnostics, utilities, and
IPC swapping.
L
laser An electronic device that converts
electrical energy into a narrowly-focused
intense beam of visible or infrared light. In
the
SLS® system , laser refers to a 30- or 70-
watt Chiller .
laser beam The focused laser light that sinters
the powder in the SLS® system .
