Systems is not responsible for losses incurred as the result of improper storage of material.
Material Disposal
Do not dump material down any drains. Dispose of material according to the guidelines given in the SDS included with the
material and according to all government regulations. For more information on material disposal, please see the section
Considerations for Material in the
Material Spill Containment
Improper operation of the machine may result in a major material spill. Your company has the responsibility to define what
constitutes a major spill. Clean up spilled material as quickly as possible, as material will cure under both natural and artificial
lighting. Personnel who are involved in cleaning up major spills of material should wear NIOSH/MSHA approved respirators
designed for use with organic chemical vapors. In addition, each person should wear protective goggles, rubber boots, and
100% nitrile gloves to minimize exposure to material, which can cause eye, skin, and respiratory irritation, as well as possible
skin allergies and respiratory reactions.
WARNING: UNTRAINED PERSONNEL SHOULD BE EVACUATED FROM THE AREA.
WARNING: MATERIALS ARE FLAMMABLE. CARE SHOULD BE TAKEN DURING MATERIAL CONTAINMENT AND
CLEAN-UP 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
material spill. The spilled 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 an absorbent cloth and IPA or
EtOH (isopropyl alcohol or ethanol). 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 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,
noncombustible absorbent 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 expiration dates are marked on the material cartridge 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. However, use
of very old material or material past its expiration date may shorten your in-service material life. Use of expired materials may
also adversely affect the build quality of 3D prints. It is advisable to check the viscosity of any material past its expiration date
prior to use.
In-Service Life
In-service life of the material is defined as the useful life of the material after having been pumped into the Figure 4 Modular
machine's resin tray. The in-service life of material greatly varies depending on material type, usage and environmental
conditions. The more volume built, the more new material will be pumped from the material cartridge into the resin trays.
This blends older material with newer material and extends the in-service life 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 contaminants are introduced such as partially cured platforms from aborted print jobs being dipped
into the resin 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 Figure 4 Modular Printer. All materials require some level of mixing to retain their properties, making
it necessary to both premix

Contamination
Care should be taken when cleaning windows, panels, and other parts of the Figure 4 Modular Printer. Cleaning products
that contain ammonia should not be used because they can contaminate the material. Instead, follow the instructions in the
