Print-Material Spill Containment
There may be certain situations that require containment of a small print-material spill. To clean the spill: wear
proper PPE; wipe up with paper towels; clean the spill as soon as possible with the
minimize UV light in the area during clean up; dispose of all waste material according to all local, state, and federal
regulations.
WARNING: UNTRAINED PERSONNEL SHOULD BE EVACUATED FROM THE AREA.
WARNING: PRINT MATERIAL FUMES 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 absorbing all spilled material, clean
the spill location with paper towels and recommended solvent. After cleaning up the spill, individuals should wash
thoroughly with soap and COLD water. Any clothing touched by material should be dry cleaned before reuse. If
material has gotten onto your skin or clothes, avoid exposure to sunlight or other UV-light sources until skin and
clothing have been cleaned of print material. Repeated or prolonged skin contact may cause sensitization. Vapor
may be harmful.
Eliminate sources of ignition. Prevent entry into drains. Absorb spilled material onto sand, earth or any other
suitable adsorbent material. DO NOT absorb onto sawdust or other combustible materials. Material spills or
uncontrolled discharges into wastewater systems must be reported to the appropriate regulatory body. Do not
discard material into drains/surface waters/groundwater. Maximize ventilation after accidental release.
Shelf Life
The length of time during which materials are certi ed for use varies by material. The expiration dates are marked
on the material bottle labels. In general, materials are usable for several months after their expiration dates,
provided that the materials have been properly stored, handled and not exposed to excess heat. For
NextDent materials, this is never the case. You must dispose of expired NextDent material according to all local,
®
state, and federal regulations. Using non-expired NextDent materials is required in order to achieve medical
certi cation for your NextDent prints. For non-Dental materials, use of very old material, or material past its
expiration date, is possible; but it may shorten your in-service material life (see below). Use of expired
materials may also result in suboptimal printing results. 3D Systems does not assume responsibility for failed
builds due to use of expired material.
In-Service Life
In-service life of the print material is de ned as the useful life of the material after having been poured into the print
tray. The in-service life of print material greatly varies depending on material type, usage and environmental
conditions. 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's in-service life. The
types of patterns and builds performed also affect the in-service life of the material. The material retains its
usefulness until a buildup of viscosity or a change in reactivity prevents further processing in the printer. All
materials require some level of stirring or spinning to retain their properties. You must NOT mix material from and
old material bottle with material from a new material bottle. These materials will be from different batches; and
mixing them could render both ineffective. Follow the Instructions for Use of the speci c material you are using for
complete instructions on getting the most use out of it.
