• Where the accident occurred
• Model and serial number of the machine
• Number of people involved
• Any other pertinent information
Please send this information to 3D Systems within a day of the accident.
Electrocution
The SLS system contains equipment energized at 208 volts, 3-phase delta. Do not attempt to remove protective panels. There
are no user serviceable parts inside.
If electrocution occurs, seek rst aid and medical attention immediately. Pushing the E-stop button will de-energize the
equipment and diffuse the hazardous situation.
Material Inhalation
The part cleaning process may create a choking or air restriction hazard. If someone has diculty breathing or a “loss of
breath” sensation, transport the person to a well-ventilated room or outside of the facility. If the condition persists, seek
immediate medical attention.

3D Systems, Inc. 10 p/n 76-D020 Rev. A
SLS EQUIPMENT SAFETY FEATURES
A major design goal for all SLS equipment is to provide a safe operating environment. The frame and enclosure designs
passively limit hazardous access while the electronics and software actively and automatically sense and react to unsafe
conditions when they arise. For example, if the SLS system detects unsafe operating conditions, it will immediately stop
operating and, in some cases, shut down completely.
CAUTION: If any SLS equipment safety features fail, your actions may be all that will prevent potentially
hazardous operating conditions.
Safety Interlocks
Safety interlock devices on the SLS equipment help prevent accidental laser exposure, electrical shocks, crush injuries, burns,
and res. SLS equipment will not operate unless all safety interlocks are satised.
CAUTION: Never try to disable or override any safety interlock device on any SLS equipment. Operating
equipment without all safety interlocks enabled can cause equipment damage, injury, or death. If you suspect
a safety interlock device is not working properly, do not operate your SLS equipment. Rather, disconnect power
from the equipment and contact 3D Systems Customer Support for assistance.
SLS System Response if an Interlock Fails
Safety interlock devices mounted on the SLS system sense the hazardous operating conditions below. The SLS system takes the
actions listed when an interlock fails.
SAFETY INTERLOCKED CONDITION IF THIS INTERLOCK FAILS...
• One or more internal print chamber panels are opena
• E-stop button pressed on user interface console
• External oxygen monitor connected to SLS system
detects too little oxygen in room
• Print will not start
• Warning message appears on SLS system display
• Red Stacklight illuminates
• Nitrogen generator (if in use) shuts down
• Warning message appears on SLS system display
• Red Stacklight illuminates
• Laser, motors, and valves disabled
• Nitrogen supply shuts off
E-Stop Only:
• CDA supply shut off
• System power disabled
a. Internal panels are for service access only. Several interlocked panels are for customer maintenance: overow cleanout,
blackbody cleaning port, and the lter box located on back of machine.
Limited Access and Barrier Shielding
SLS equipment frame and enclosure designs limit access to the following:
• Service areas, such as cabinets and enclosures for electrical power and automation controls. This prevents accidental ex-
posure to electrical shock hazards.
• Material areas, such as material feed hoppers, storage bins, and transport tubes. This prevents:
• burn hazards by minimizing exposure to heated material
• slip hazards by keeping material from dropping on the oor
• re hazards by minimizing airborne dust cloud formation and potential ignition. See SDS for complete material hazard
details.
• Laser beam optics and scanning areas, including the fully-enclosed Laser Enclosure—where the laser beam originates—
and the interior of the print chamber, into which the beam projects. The Laser Enclosure and print chamber are designed
to minimize hazards such as burns, eye injury, and re in the following ways:
• The Laser Enclosure optics and laser beam duct (at the top of the print chamber, below the removable Laser Window)
prevents the laser beam from being aimed outside the print chamber.
• The fully enclosed print chamber blocks laser radiation from escaping to the outside.
• The material of the print chamber window also blocks laser radiation so you can safely observe the part bed during a
print.

3D Systems, Inc. 11 p/n 76-D020 Rev. A
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 certied 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 certied electrician.
ELECTRICAL HAZARD: Do not open the panel behind disconnect switch! Live voltage present. This should only
be opened by qualied 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 certied 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.

3D Systems, Inc. 12 p/n 76-D020 Rev. A
LASER SAFETY
The SLS system contains a 100-watt continuous-wave CO2laser. The laser itself is designated Class IV. Very brief exposure to a
direct—or specularly or diffusely reected—laser beam can cause signicant burns or eye damage. It can also be a re hazard.
During normal operations of the SLS system, the laser beam path is wholly contained within the machine. This makes the entire
machine a Class I Laser System. That means the SLS system does not produce damaging emissions under normal operations.
Laser Safety Classications
Class I and Class IV are designations established by the U. S. Department of Health and Human Services, Public Health Service,
Food and Drug Administration, Center for Devices and Radiological Health (CDRH), and by IEC 60825 (the International
Electrotechnical Commission’s Radiation Safety of Laser Products, Equipment Classication Requirements, and User’s Guide). The
Class I and Class IV laser designations also comply with DIN VDE 0837/02.86+A1/07.90. You can read more about laser safety
and classications in ANSI Z136.1-1993 (the American National Standards Institute standard for the safe use of lasers).
Laser Safety Labels on the SLS system
The SLS system has the two types of laser safety labels below. Laser safety label locations on the SLS system are shown in the
gures that follow the table:
LASER SAFETY LABEL WHAT IT MEANS
LASER RADIATION HAZARD
Invisible laser radiation is accessible in the vicinity of this sign or behind
the access panel. Direct and scattered radiation can cause severe burns
and eye injury, or start a re. Access panels are for service only and
should only be opened by certied service personnel.
DEFEATABLY INTERLOCKED PROTECTIVE HOUSING
If you defeat the SLS system laser safety interlocks, then open this
housing (panel or door), you can be exposed to hazardous direct and
scattered Class 4 invisible laser radiation which can cause severe burns
and eye injury, or start a re.
LASER CERTIFICATION/IDENTIFICATION
Identies laser system Class and shows CDRH Statement of
Compliance.

MATERIAL SAFETY
All materials certied by 3D Systems are safe during normal operation. However, you should be aware of the following issues:
• Any material, material-like substance, or airborne cloud of material has a remote chance of rapid combustion.
• Breathing some materials may cause certain people to experience respiratory irritation.
• Material safety hazards are minimized by good industrial housekeeping and ventilation practices.
• Spilled material can cause the oor to become very slippery.
• Material should be sifted in a well-ventilated room.
Refer to the SDS’s and to 3D Systems material guides for information on specic materials.
CAUTION: Using materials that have not been certied for use in the SLS equipment may cause health or safety
hazards and may damage the equipment and void the warranty.
Material Ignition Information
Powdered materials can be ammable and can be ignited by static electricity in a non-inert environment. Refer to each
material’s SDS for specic information.
CAUTION: The operator must use an approved vacuum cleaner to clean up excess material. 3D Systems
recommends an ESD or explosion-proof model. Contact 3D Systems Customer Service for purchasing options.

Material Handling Precautions
During normal operation of the SLS system using 3D Systems’ materials, you are not required to wear a dust mask or special
personal protection equipment unless specically designated. Check the SDS of the material used for the specic precautions
you should observe. Use the following table of precautions as a general guide:
Safe Material Handling Guidelines
CATEGORY PRECAUTION
FIRE/HEAT
• Never smoke or ignite anything around powdered materials.
• Maintain proper clearance from materials when using portable heating devices.
• Store ammable liquids away from materials.
• After removing a part from the print chamber, allow it to cool to room temperature in a well-venti-
lated area.
• Use anti-static mats in front of SLS equipment.
INHALATION
• Avoid breathing powdered materials; when exposure to dust or fumes is likely, wear a NIOSH-ap-
proved respirator appropriate to the airborne concentration.
• Always provide adequate ventilation.
SHOP SAFETY
• Train operators in SLS system procedures.
• Wear safety glasses.
• Use extreme care with all heated materials.
• Make sure that the room is well ventilated.
AVOIDING SPILLS
• Keep containers closed when not in use.
• Have a fully-grounded internal non-ignition vacuum cleaner ready to use.
• Have any equipment specied in the SDS ready to use.
SDS
• Give operators access to the SDS’s that apply to materials they will be handling and ensure that
they read them. If necessary, translate them.
• File SDS’s in an easily accessible location for immediate reference.
• Strictly follow all the conditions in each SDS.

NITROGEN/OXYGEN SAFETY
The SLS system uses nitrogen to create an inert atmosphere in the print chamber. The nitrogen inhibits any potential rapid
combustion of particulate matter during the SLS process.
The oxygen content of air is approximately 21 percent. Displacement of the normal atmosphere with an inert gas, such as
nitrogen, can reduce the oxygen content in a room. In the remote chance that nitrogen leaks into the room during the sintering
process, the situation can be hazardous.
Your site must have an oxygen alarm monitor installed in the room containing the SLS system. This monitor will alert you if
the oxygen level drops below a designated point. It must be wired to trigger an immediate shutdown of the SLS system and
nitrogen generator (if in use).
CAUTION: Exposure to an atmosphere containing 12 percent or less oxygen causes unconsciousness without
any warning symptoms. This happens so quickly that you cannot help or protect yourself.
The table of Oxygen Deprivation Effects and Symptoms explains the potential effects and symptoms that can occur at
different concentrations of oxygen in the atmosphere.
When you work in an environment that may become oxygen-decient, make sure you comply with the following items:
• If, at any time, you feel you are experiencing symptoms of oxygen deprivation, leave the area immediately.
• You have received oxygen/nitrogen safety training.
• The room is well-ventilated; at least 4 air exchanges per hour.
• Self-contained breathing apparatus is available and easily accessible.
• The room oxygen alarm monitor is functioning and audible.
• Leave the SLS system room/area immediately when you hear the oxygen alarm.
Oxygen Deprivation Effects and Symptoms
OXYGEN CONTENT
(% BY VOLUME) EFFECTS AND SYMPTOMS AT ATMOSPHERIC PRESSUREa

This section gives an overview of the part printing process.
The software used to print parts on the ProX® SLS 6100 printer consists of the 3D Sprint and Sinter applications. 3D Sprint is
used to prepare models for printing. The models are then processed and transferred to the Sinter application which controls
the printing of the parts.
Before printing, several components of the SLS equipment should be cleaned and the ProX® MQC System must have
transferred material to the printer.
PROX® MQC SYSTEM PREPARATION
The ProX® MQC System should be started and lled with material before proceeding. After it has been loaded with material, it
will need to transfer the material to the printer.
The ProX® MQC System must be in Full cycle mode for material to be sent from the blended bin to the ProX SLS 6100. Before
selecting Full or Local cycle mode, the user should verify that the desired blend ratio is selected. (See Material Guide for
recommended ratio.)
4PRINTING PARTS WITH THE PROX® SLS 6100
PROX® SLS 6100 START-UP SEQUENCE
If you’re starting the printer from it’s powered-off state, you must rst perform the following machine start-up sequence before
you start a print:
• Verify the system’s clean, dry, compressed air supply
• Verify the system’s nitrogen supply
• Verify the system’s material supply
• Put Sinter in Manual Operations (Man Ops) mode
• Move the part piston to its Home position
• Move the roller to its Home position
• Move the piston back to its Start position
Instructions for each step in this sequence are described next.
If you’re starting the printer from its powered-off state, do not attempt to start a print before you perform the
startup sequence. Also, never attempt to start a print if the dsp button is not shown in the taskbar. (Putting
Sinter in Build mode then opening a build packet starts a build.)
1. Verify the printer’s compressed air supply.
a. Verify that facility compressed air is on and connected to the gauge panel AIR INLET.
b. The air pressure gauge label indicates the correct reading. This should be: 350 KPa (50psi).
2. Verify that the system has an adequate supply of nitrogen.
NOTE: Skip Step (a) if you have a nitrogen dewar or bulk tank connected to your SLS system instead of a
nitrogen generator.
a. Open the compressed air supply valve at the bottom of the N2generator.
b. Make sure the NITROGEN INLET ball valve on printer’s gauge panel is open. It needs to be turned at a 90° angle so
that it is aligned with the direction that the nitrogen is owing.
c. Verify that the regulated N2PRESSURE gauge on gauge panel reads 140 KPa (20psi).
3. Verify the material supply using either of the following two ways.
• In Sinter, check the ProX MQC System’s window in the Man Ops screen. This displays the ProX MQC System’s status,
including the amount of available powder.
or...
• Check the ProX MQC System’s status in the Sinter Status window which also displays the amount of available powder.
