SLS® system S elective L aser S intering system.
Machine for building part s using 3D Systems’
SLS technology. The two latest SLS® system
models are the
s
Pro 140 and
s
Pro 230.
SLS S elective L aser S intering: A thermodynamic
process in which directed laser energy heats
particulates in a defined pattern, fusing them
into a solid mass. SLS is one of several
3D Systems’ rapid manufacturing and
prototyping technologies. SLS is and integral
part of 3D Systems’
SLS process that creates
solid part s from 3-D CAD files. It makes part s
by rolling a thin layer of powdered material
across a
part bed , heating the part bed to just
below melting, then scanning a cross-section
of the
part s with a high-power (up to
100-watt) infrared laser . The scanned cross-
section “ sinter s” (partially melts, then
solidifies), adhering to the scanned cross-
section on the layer below it. Unscanned
areas remain loose, solid powder. After a
layer
is scanned, the part bed drops one layer
thickness and the cycle repeats until the part
build is complete. At the end of the build , the
loose powder is removed from the layered
part cake .
