Other Active Safety Features
•
The ProX® MQC System, coupled with the
Dust Collector
, removes airborne material during part breakout in accordance
with standard industrial ventilation practices .
•
An optional room oxygen monitor automatically initiates SLS system shutdown when it detects too little oxygen in the
room .
•
Software in the SLS system automatically initiates immediate equipment shutdown if certain unsafe conditions are detected
during operation .
ELECTRICAL SAFETY
To prevent electrical shock, SLS equipment will not operate unless all external panels are installed and all electrical safety
interlock circuits are closed .
ELECTRICAL HAZARD: Hazardous voltage exists inside the enclosures of all SLS equipment . Injury or death from
electrical shock can result if you remove external panels or try to defeat safety interlocks . Panels should only
be removed, and interlocks should only be defeated, by trained and certified 3D Systems Customer Support
personnel .
ELECTRICAL HAZARD: Verify your facility’s electrical service ratings before connecting power to any SLS
equipment. Power must only be connected by a certified electrician.
ELECTRICAL HAZARD: Do not open the panel behind disconnect switch! Live voltage present . This should only
be opened by qualified personnel after power is disconnected from the facility’s power circuit/breaker panel.
All SLS equipment was designed to minimize operator exposure to electrical hazards during normal operations . All exposed
electrical circuits are inside limited-access cabinets . This is to separate the operator from service and maintenance areas .
When operating any SLS equipment, keep the following electrical safety points in mind:
•
Only 3D Systems certified service personnel should operate SLS equipment with access panels or service doors open.
•
Heed high voltage warning signs and labels .
•
Take common-sense safety precautions when operating any electrical equipment .
•
After any change to the electrical wiring, make sure the equipment is properly grounded .
ENVIRONMENTAL ISSUES
The SLS system emits no toxic substances when using materials approved by 3D Systems .
Emissions
Material heating
– Analytical testing on 3D Systems materials indicates no detectable emissions outside acceptable limits from
the SLS system . (See the materials’ SDS .)
Nitrogen
– The SLS system uses nitrogen, which is passively vented in the print chamber .
NOTE: Do not install a fan in the exhaust port . The exhaust port in the print chamber must not be blocked . The
nitrogen-inert atmosphere in the SLS system print chamber is at higher pressure than the outside atmosphere .
The chamber will vent without a fan . Installing a fan in the exhaust port will draw nitrogen-rich air out of the
print chamber too fast, raising the oxygen concentration in the chamber . This can keep the SLS system from
reaching inert status, or cause an in-process print to abort .
Material Disposal
Refer to the DuraForm ProX® material SDS for disposal information . Follow any applicable local regulations .
