The SLS system emits no toxic substances when
using materials approved by 3D Systems.
Emissions
Powder heating – Analytical testing on
3D Systems powders indicates no detectable
emissions outside acceptable limits from the
SLS system. (See the
MSDS ’s.)
Nitrogen – The SLS system uses nitrogen, which
must be passively vented to the outside.
L
Do not install a fan in the nitrogen vent. The
nitrogen-inert atmosphere in the SLS system
process chamber is at higher pressure than the
outside atmosphere. The chamber will vent
without a fan. Installing a fan in the nitrogen
vent will draw nitrogen-rich air out of the
process chamber too fast, raising the oxygen
concentration in the chamber. This can keep
the SLS system from reaching inert, or cause an
in-process build to abort.
Waste Heat
Almost all the electrical power used by the SLS
system and RCM is converted to heat that must
be removed from the room. Air conditioning for
the installation room should be sized based on
room dimensions; the size, number, and location
of wall openings (such as windows and doors),
the number of people typically working in the
room, and the electrical power supplied to the
SLS system(s) and RCM(s).
Use the

Pro SLS system, RCM-140, and
RCM-230 electrical power requirements below

Powder Disposal
Refer to the DuraForm material MSDS for disposal
information. Follow any applicable local
regulations.
