SLS process (SLS™ process) 3D System’s process
for creating 3-D models and end-use part s
from powdered materials starting with a 3-D
CAD file. The SLS process proceeds in three
steps:
build preparation , build , and breakout .
The following 3D Systems SLS equipment
play major roles in the SLS process: IRS , IPC ,
RCM , SLS® system , Nitrogen Generator , and
BOS . Auxiliary machines include: Chiller ,
Room Oxygen Monitor , Dust Collector , Bead
Blaster, and Non-ignition Vacuum Cleaner.
sort To arrange facets in an
STL file in ascending Z
order.
sorted facet file A file that contains the facets in
the STL file sort ed in ascending Z order. The
software creates the sorted facet file when
you verify
part s in the Build Setup
application. You can display sorted facet files
in
Build Setup . A build requires a sorted facet
file.
SPI S erial P eripheral
I nterface. One of two
BOS / RCM
communications modes set using the BOS
RCM Com Mode process parameter.
stage One of three
separate, consecutive
states of a
build . Each
stage has a separate
build profile .
Standby mode The mode
(in both the IRS and
BOS ) in which air flow is
shut off and powder
transfers are disabled.
All other functions, such
as setup and diagnostics, are available in
Standby.
STL file A file produced by a CAD system. The
SLS® system computer uses this file to
generate a build. It is composed of triangles
connected at vertices that represent exterior
and interior surfaces. It can be either ASCII or
binary. Users can read ASCII files, but in
general, binary files provide better space
conservation and system performance.
Stop

stray vectors A build defect where
unintentional scan line s distort the part
shape.
SYSTEM SECURE light When this green UI
console light is on, all SLS® system safety
interlock s are satisfied.
