Laser
• Do not try to access, service, or adjust the laser system in any way.
• Do not enter any area displaying posted warning signs during open beam operations. Open-beam operations refer to the
laser, and they only occur during service procedures.
Alarms and Warnings
• Displayed error, alarm, or warning messages can result from unsafe practices, such as opening an enclosure door or panel
when equipment is powered up and running.
2.1 Intended Use
The Gravity is a commercial, precision tool intended for use in the additive manufacture of end-user supplied designs from
polymeric powders. The final performance characteristics of fused powder may vary according to your compliance with the
instructions for use, design guidelines, application, operating conditions, material combined with, end-use, or other factors.
Note: In some cases, the additive manufacturing process may inherently result in variable performance
characteristics between manufacturing runs or within a specific part. Such variances may not be apparent
and may result in unexpected defects in additively fabricated parts.
The Gravity should only be operated by trained personnel and as described in this document.
Do not carry out any disassembly or tampering with the machine that is not described in the manual.
This equipment design typically applies to commercial or industrial equipment expected to be installed in locations where only
adults are normally present.
Gravity is a Laser Class 1 product. All laser radiation is completely enclosed inside the machine.
WARNING: THE GRAVITY BECOMES VERY HOT INSIDE THE BUILD CHAMBER AND ADJACENT PARTS. NEVER
TOUCH THE INTERIOR SURFACES OF THE GRAVITY OR THE HEATING ELEMENTS. ALWAYS ALLOW THE GRAVITY TO
COOL DOWN.
In case of any Gravity breakdown contact 3D Systems for service and maintenance.
2.2 Personal Protective Equipment
Face Mask
Wear Protective Mask: A face mask should always be used when handling loose powder in order to minimize
the amount of inhaled particles. The powder is not toxic but consists of small particles that could cause
irritation in the respiratory passage when inhaled.
Protective Gloves
Wear Protective Gloves: Protective gloves should be used when evacuating the machine after a finished print
job since some parts of the machine could still have elevated temperatures. Gloves are also recommended
during all handling of loose powder.
Hot Surfaces
Hot Surface: During a print job, the temperature in the machine is elevated, above 100 degrees C, and the user
needs to take caution when touching the machine from starting the print job until the machine notifies the
user that it is ready for removal of prints.
WARNING: THE HINGES FOR THE DOOR SHOULD BE AVOIDED DURING A PRINT JOB.
