Shelf Life; In-Service Life; Contamination; Polymerization - 3D Systems ProJet 6000 User Manual

WARNING: Untrained personnel should be evacuated from the area .
WARNING: Print materials are flammable. Care should be taken during print material containment and cleanup
operations .
A supply of dikes and control booms should be stocked so they are available to contain the affected area in the event of a major print
material spill . The spilled print material should then be absorbed on inert absorbent material and placed into drums for transfer to an
approved waste disposal site . After cleaning up the spill, individuals should wash thoroughly with soap and cold water . All clothing
should be washed before reuse . Avoid exposure to sunlight until skin and clothing have been cleaned of print material . Refer to the
MSDS before using any chemicals . Repeated or prolonged skin contact may cause sensitization . Vapor may be harmful .

Shelf Life

VisiJet SL & Accura materials are certified for use for at least 12 months from their date of manufacture. Most materials are certified
for 18 months from their manufacture dates. The recertification dates are marked on the material cartridge labels. In general, resins
are usable for several months after their recertification dates provided that the materials have been properly stored, handled and not
exposed to excess heat. However, use of very old or material past its recertification date may shorten your In-Service material life. It is
advisable to check the viscosity of any material past its recertification date prior to use.

In-Service Life

In-Service Life of the VisiJet SL materials is defined as the useful life of the material after having been poured into the ProJet 6000 print
tray . The In-Service Life of the Projet 6000 material greatly varies depending on material type, usage and environmental conditions . The
more volume built, the more the material is refreshed with newer material . This blends older material with newer material and extends
the In-Service Live of the materials . If the material is exposed to temperatures outside of the normal operating limits, is exposed to UV
light, is exposed to particulates or vapors in the air such as dust or fumes, or if contaminates are introduced such as partially cured
platforms being placed back into the print tray, this will shorten the material In-Service life . The type of patterns and builds performed
also affect the in-service life of the material . With all this taken into consideration, we would expect the in-Service life of the material to
be at least two years but can be much longer with proper care and maintenance . The material retains its usefulness until a buildup of
viscosity or a change in reactivity prevents further processing in the ProJet™ 6000 .

Contamination

Care should be taken when cleaning windows, panels, and other parts of the ProJet™ 6000 . Cleaning products which contain ammonia
should not be used because they can cause contamination of the material . Instead use a small amount of isopropyl alcohol on a paper
towel to clean up spills . Accidental contamination of resins may change the material's performance characteristics to such an extent that
acceptable parts can no longer be reliably created .

Polymerization

Signs of polymerization of stored resin include container bulging, leaking, and the emission of heat, or an unusual odor from the
container . If you notice this, do not use the material and dispose of it properly .

ELECTRICAL SAFETY

To prevent electrical shock, the ProJet™ 6000 will not operate unless all external panels are installed and all electrical safety interlock
circuits are closed . The ProJet™ 6000 was designed to minimize operator exposure to electrical hazards during normal operations . All
exposed electrical circuits are contained within limited-access cabinets . This is to separate the operator from service and maintenance
areas .
WARNING: Hazardous voltage exists inside the enclosures of the ProJet™ 6000 . 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 safety
interlocks should only be defeated by certified service personnel.
